I call Tow boat usa once a week and save a ton of money on fuel. I call them for inbound trip because I don't want to drive back drunk and I like to save on fuel .. membership has its rewards.
I really hope this is real 🤣
I tried that twice and after the 2nd time they revoked my membership that does not work
@@adraper30 you’re a legend
Nice to know I’m not the only one that does this!!
@@jd3953 😂
I think this channel should be required watching for anyone looking at getting into boating. Excellent content. Such a blessing.
Thank you!
I’m that person.
I don't know about "required" but certainly the best I've found. I'm just getting back into boating after 12 years and I've learned things here I've never known.
I agree.
This is one of the few channels I have ever clicked the notification bell on 'ALL'!
Amazing source of info. I have a new job at a marine shop so I'm here learning everything under the sun. Thank you for being exact, precise, and knowledgeable on nearly if not all boating subjects.
I don't even have a boat and I watch as many of the channels as I can to learn as much as I can. I just recently sub'd, like this morning, to BAB. The technical aspects and opinions are about the best of I have come across. I am 62 and medically retired on a fixed income. With that being said, I still am looking to get an older Wellcraft 248 Offshore to refit and use for fishing with my younger brother. I am of the opinion after having used a rental with a four stroke 200 Yamaha that I will be re-powering with a 4S 250 Yamaha on a bracket. It my never come to fruition, but I can research and plan my boat based on the information available. I was aware of the general idiosyncrasies of a boat's makeup, but I never had cause to get really in-depth into it like my sister and BIL who are avid boaters with a 26' Formula and a 32' Tempest. Now more recently taking notes in my dedicated notebook. Thanks for sharing your knowledge with the tadpoles. BTW, the Offshore will be used primarily in fresh water, in Lake George New York.
I agree with everything your video stated. I have also been told that using a jack plate to remove even more of the engine from the water will also decrease fuel consumption dramatically, with no loss of speed.
I recently downsized from a 24' with 225 Johnson 18gph cruising, to being super happy with my parker1801 and its fuel sipping consumption. I typically get 4.5gph fully loaded at gps 27mph #gaugesaver
I've never measured my fuel consumption, but determined my optimal cruising speed by listening for when the motor sounds to be freely running (doesnt sound like it's under much of a load). Plenty of smooth water and distance to mess with speed and trim on the Missouri river. Around 35mph. Bayliner 212 cuddy with a 5.0l.
Agree. Often the best indication is the sound & feel.
2005 20’ seahawk w/ 150ph 2 stroke. Haven’t tinker with it enough to get to the sweet spot. I’ll definitely will pay more attention to it now. Thanks for the awesome video. #gaugesaver
Love the video! I have a 1994 Searay 34 foot express cruiser I cruise about 20 kn at 3000 RPM roughly 16 gallons an hour which prior to this video I thought it was really bad but she’s a very large boat 11 1/2 foot beam I’m actually quite content with my numbers now thank you for the video I’m going to make a video about this thank you guys
25'-6" Cobia CC with twin Yamaha F115's - Best economy is 28-30 MPH getting around 2.7 to 3 MPG depending on load and sea state. WOT is 40-42 MPH I didn't know when I bought it (used), but the props were not matched correctly. They were both the same size (according to the casting stamps) but I could never reach full RPM on my port engine. It was always 2-300 lower than the starbd.
Took it to a mechanic and he diagnosed a high pressure fuel leak inside the VST and also that the cupping of one prop was different than the other. After fixing the fuel leak I lake tested and was about 150 rpm lower then. I found a pair of matched props 13x17 - 3 blade, put them on and bam, back up to 6K on each engine now. I keep the originals as emergency spares now, and can fix my own VST fuel pump issues :-)
PS - Eric aka UncleBob at Gaugesaver is awesome, they redid all my gauges three years ago and turned out fantastic! I bought some of the rubber covers and they still look good. We are planning a #FPTower trip in May sometime looking for mahi and maybe a stay out there too!
Great video. Thanks again. At the end of the day It's all about SMILES PER GALLON!
Lol :)
Interesting live data and these are methods everyone can use to fairly accurately determine their own fuel consumption. Thanks well explained! The newer mercs have a type of fuel saving programmed into the ecm. After staying at the same Rev range for more than 2 seconds the fuel mix becomes step for step reduced and the igniting point advanced up to the point of knocking, saving up to 30% fuel! ARO advanced range optimisation.
Enjoy saving fuel for more boating
Yup! Suzuki's do the same thing too :) That ARO lean burn is amazing though! You never know when it's working though, unless you are watching the data on the laptop :)
Excellent video - lots of great info. I've been aware of the benefits of trimming up for years but did not realize it could be THAT dramatic. Unfortunately the gauge package on my 2004 Scout Dorado 175 doesn't report fuel burn and the fuel gauge is incredibly crude so I'm going to have to install some kind of aftermarket fuel burn meter. (Hey, how bout that for a future Tech Tues!). What I did figure out a couple years ago by topping off the tank, taking a two hour run, one heading for half, then reverse heading home, then topping off again and doing some math was that a slow plane of about 22 mph constant, just me, and that full 30 gal tank, it worked out to just 2 gal/HR out of the Yamaha 90 4-stroke. That really impressed me (cuz I'm a cheap SOB... 😎). I'd say tho my normal cruise is closer to 30 mph (WOT gets me 40...) so Im looking forward to recalculating. I just wanted to see how little fuel I could burn that first run.
2016 Tracker targa V20 , 150 mercury 4 stroke, wasilla, AK. Thank you for the informational videos!
My boat is 24 feet and I have 2 Mercury Optimax 135 (my 2007). My cruising speed is about 24/27 knots (around 3.500 rpm) and about 34 liters per hour (9 gallons/h). Top speed is 43 knots.
Good day,
2015 260 SeaRay 350 dual props.
Gets up, and stays up on plane,with the help of trim tabs,at a speed of twenty five mph at thirty two hundred RPM.
I used Gauge Saver to repair an unreadable Lowrance LMF 400. Looks new and they included a gauge bra to minimize exposure when not in use. Turn-a-round was very reasonable. This gauge is hard to find and expensive.
2000 Sea Hunt Victory 21" cuddy walk around w/ 1999 Johnson 175 hp 4 blade Al. prop V6. with Trim tabs. 34 to 36 mph fully planed. I usually run about 3400 rpm's @ 28 mph.
1972 Thunderbird Runabout. 50hp outboard. Top cruising speed 22-25mph. Still need to do some more motor trim testing. Thanks for the informative vid 🤙🏻
As always love the info in your videos!!
The opposite of this trick can also be used if you know you're going to be facing rough weather. For instance if I know I'm going to be going out almost a full day and burn half a tank of fuel I fill her up to the brim in the morning and add some extra weight as well. A heavy boat will consume more fuel but is also a lot more stable in rough weather. Basically the experienced skipper will use the weight of the boat to his advantage under varying conditions, sometimes light and sometimes heavy. And it also depends on the boat of course, my boat has the fuel and water tanks in the center console so it's central weight which helps calm the boat down.
150 opti fishing with a 20ft sunbird we fish 6 hours from idling to fast move to different spots we burn about 1/2 mercury 5 gallon tank. It gives my sons 25hp mercury a run for its money on fuel economy fishing wide-open cruising it will get hungry but not that bad. AMAZING.. i GUTTED that boat when I got it redid all the stringers and foam its so lite my little wife can push it around the shop we keep the belly tank 1/2 full for ballast for fear of being tipped over.
Finally a relevant useful video, great job looking forward to the next one.
#GaugeSaver. We will see this summer with the brand new mercury 150 that we bought yesterday. Delivery date soonnn 🤩. It’s impressive to see how efficient a motor can be when adjusting speeds and trim. Never imagined to be that much. Need to invest in a more modern gauge now. Great tips 👌
I had to watch this three times just to capture all the information you squeezed into 10 minutes; it is uncanny!
I have a 2001 cobra rib 7.5m (25foot) with a Mercury optimax 225hp, best cruise at 33mph get 8gph average load, 53mph wot gets 20gph. I find weight is also a big factor to speed and economy.
20' trophy walk around with a 150hp 2 stroke Mercury. I cruise at 38mph at 3/4 throttle trimmed up as high as I can.
my boat doesnt use any fuel at all at the moment ,! cos were not allowed out , but when we are i will give this a go
Man you all rock! Such good information man.
Wouahhh,..Quel merveilleux système ? Économie, économie !!! Très très brillant ! 👌😎
#GaugeSaver
Watching your RPM'S can help find that efficiency sweet spot. You'll notice a point where it's take a few more R's to gain the next MPH. Great info as usual!!
Had a 230 Sundancer with a 5.0 Mercruiser. Cruise speed was about 23 mph at 3200 rpm at about 11 gph, and a little better than 2 mpg.
Whenever I feel like my Old 2 Stroke single 115 uses a ton of fuel, I watch a video like this where it makes me hush my mouth. Smiles per gallon can get expensive 😁 #gaugesaver
My boat's crusing speed is around 5kts. Regardless of wind or horsepower. Whether under sail or auxiliary outboard 😂
Great, and I mean great video. Perfect tempo, really useful information, subscribed and liked.
Thank you!
Great information.... thankyou for sharing !!!.
I booted all my free loading friends out of my boat in favour of friends who understand the costs of running a boat and help with the cost of running mine.
Problem solved😁
Literally just learned my lesson last week. Took three friends and their kids (5 people) our dipnetting for salmon in the kenai river here in Alaska. I paid for gas, launch and they got air BnB and didn’t even think about where I was gonna stay as we had planned to camp. I had to go find a campsite at 10 pm and they expected me there at 6 am so they could get one water before the low tide boat launch closure which lasts 2 hours till tide is high enough. I showed up at 9 😂 took them out and made them all ride in their compact car as I stayed an extra day and so they couldn’t have two of them ride with me back as they couldn’t stay the extra day. I let them bitch and complain and had a great night after they left and a friend of mine who actually understands boating and the next day she drove an extra 50 minutes past her house to help me clean the boat and fillet the fish etc. needless to say those people are gonna have to dipnet from shore next summer and aren’t invited back in my boat.
matanuska high First congratulations on living in such a beautiful place. I have lived in British Columbia all my life 60+ and have fished the whole coast both commercial and sport.
I like how you handled that one and better yet your friend who drives 50 miles to help. She should get second mate status.
Enjoy the summer.
@@MatanuskaHIGH
Well, like the old saying goes, "With friends like those, who needs enemies." lol
Lived in Anchorage back in the late 70's. Saw a turnip at the State Fair the size of a basketball, about 18 lbs. I think from the Matanuska Valley. Any Thunderfk still growing out there? Love your name so I thought I'd ask.
Seal M Thunderfk lol now theres a name I had forgotten.
Seal M well thunderfuck isn’t just one strain of cannabis. It’s basically any good weed coming out of the valley back then was called thunderfuck to sell better and higher price. Being indoor was a new thing in the 70s and people starting growing higher quality compared to commercially available weed it became legend in that way. But too many people claim to have it and they are all different genetics going back to the 70s. Plus there is a lot of better herb around now days. I work in a legal extraction lab running different types of cannabis extraction equipment and also have spent about 25 years growing I can safely say the MTF aka matanuska thunderfuck is more or less a myth and a name given to all types of good weed back in the day.
Enjoy your videos.
I have an Intrepid 377 with trip 300 Verados. My boat also has a Marlin tower with hardtop. My sweet spot is around 4200 rpms at 36 mph. At that point I am getting 1.02 mpg or just over 10 gph per engine. Could really use #gaugesaver
Your math is way off . . . unless by saying "just over 10 gph per engine" you mean 11.765 gph per engine. Or, more likely, by saying "getting 1.02 mpg" you really mean getting 1.2 mpg.
1988 22' Angler w an Armstrong bracketed 200 Johnson, don't know my cruising speed yet because I've been working on it all winter and just fired it up for the first time yesterday. Sure could use some new gauges! 😃👍 #gaugesaver
Don't have a digital gauge but will still mess around and figure mine out 19 ft open bow or deep v hull 4.3 v6 MerCruiser
Used tooth past on my headlights and in 20 minutes they looked like new ! You’ll be amazed!
2016 Key West 210 Bar Reef with the 250 Yamaha SHO. First off, I never "cruise" looking for best fuel economy. I know my WOT fuel consumption is around 25 GPH at 65 MPH (6,200 RPM). I usually "cruise" around 4,500 RPM at 45ish MPH. No Idea what the fuel consumption is at that speed. Might check it this weekend.
22 ft Sea Pro CC with a Yamaha 200 HPDI , I'm seeing about 13 Gph at 30 Mph
I was exercising a customer’s 37 intrepid and it would top out around 65mph with triple 300’s and then we filled up the huge live well and it lost 5mph off it’s top speed lol. We also had another customer that was really picky about his speed on his 39’ nor tech with quad 400’s, even though it smokes anything it comes across he still never wants to fill it with fresh water and made sure his outriggers were carbon fiber. He ordered a 452 super fish with quint 450’s but he deleted the generator, sea keeper, and bow thruster options just to save weight. Basically he deleted the re-sale value as well.
It's wild how the weight can affect it so much. Lol on the re-sale value! Sounds like a speed addict with a disposable income :)
Or a drug dealer lol
Oh the joys of having stupid amounts of disposable income huh......
Does this work with a sterndrive, or only outboard. Is it recommended to adjust the outdrive when under power
#GaugeSaver 19' Stingray 3.0 (135hp), max 42mph. Cruise 30 mph but this is based on lowest RPM for best speed as I don't have fuel flow. And yes, I've found to trim nose up until she starts purposing.
My 18footer is very broad and shallow in draft with a 115 ficht 2 stroke. Having hooked up an entire Minn Kota system with an old 105 trolling motor in the bow I simply use the the gas engine to power the batteries from time to time to keep them topped off. I have been looking at jack plates for any next *real boats* as discussed here but power to weight ratio on an engine in addition to durability and simplicity really matter. Not a fan of the Engineering that is a 4 stroke motor at all therefore. Most go with diesels if fuel economy is the goal anyways. Big fan of the old Detroit Diesel 2 stroke as such. Having said that the purpose as I see it with gasoline motors is the same as for a car namely running all the accessories on a boat which are many now. A/C, heating, electrical, a gyro stabilizer you name it a gasoline outboard engine is a very valuable property of any type or condition.
Generally speaking, prop shaft should be parallel with the water surface. Trim up as much as possible, adjusting trim to maximize speed.
That can-t be right - the faster I go the more I trim up and the flatter the boat rides.
@@peterdarr383 So your maximum speed is full trim up?
The flatter the hull in water, the more wetted surface and this creates drag , especially if the bow is being forced down (stern being forced up).
Anyway, generally with the correct x-dimension and decent hull shape (not excessive rocker, no huge hook, etc.) the prop shaft will be near parallel with the water.
@@thisisyourcaptainspeaking2259 No, not trimmed-up the whole way, that's not what I said. But also the appropriate trim at 25 MPH is "nose-down" at 50 MPH, thus as I go faster, I trim "up". My hull appears straight, with no rocker or hook. A Bayliner 175. So as I go faster, I assume the nose goes a bit down.
@@peterdarr383 You should be adjusting the drive position to maximize the hull speed. Generally it's not necessary to readjust aside from the initial hole shot, depending on the circumstances. You may find it necessary to forgo some speed in order to raise the bow in rough conditions, this positions the hull better for crashing through chop.
Regardless, the prop shaft will be very near parallel with the water surface. Bayliner hulls have a decent profile IMO, Sea Ray as well.
All boats have rocker, shorter boats tend to have more and this can lead to porpoising Hook often is a result of improper trailer position, although some hulls will have some small amount built in to help tame their handling characteristics. I don't recall seeing any hook in the Bayliner hulls.
Always great content.
Have a 19ft seapro with a 115 Mariner. My cruising speed is about 60mph....................on the trailer being pulled down the highway. Good video.
Lol :)
Do a video where you test all the different prop brands!
Great content 👍 thanks
Got a link to that fuel gauge? Great tips
just lifted my 300 yamaha up 2 holes on my 23 Regulator... cant wait to get it in the water and check out fuel burn if i can see it thru my faded yami gauges... #gaugesaver
How did it turn out?
I have no idea how much fuel I’m burning per hour because my boats gauges only work when they feel like it, but I know it’s a gas guzzler lol. #gaugesaver
2000 bayliner Capri, we are out of gas at half tank, apparently redline at 11k rpm, doing 65 mph at idle, throwing -3 volts on the battery, and 15 F engine temp. Gotta love boat gauges, especially old cheap ones lol
Which cluster do I need to measure fuel consumption in a 200 hp Yamaha 4 stroke 2014 ? Thanks
6.5x2.5 centre console boat, with FPT 230hp inboard diesel with Bravo 3, 26knots 3.7g/h 42knots 10g/h.
We in the UK are on approximately equivalent per gallon 7$ or £1.25p per ltr £6.25 per gallon
Fuel costs here are 30 - 40 % more expensive, would run the boat for economy rather than thrills or just speed.
I think you might need to update UK marina petrol prices…..
I Was looking online for fuel consumption for my new (to me) motor and I found a guy who had almost the same motor who had plotted his fuel consumption vs. rpm. Great resource. But the funny thing was that his boat must have been really slow or lame, because this thing went from like 12 mph to 30 mph between 2500 and 3000 rpm. That thing must be hard to plane. I hope mine isn't that weak. But his best fuel mileage was around his lowest planing speed ... 3000 rpm, give or take, but it was similar for up to around 4k.
That's normal, and shows that at 2,500 RPM he was "plowing" , not "Planing". Some of the "wakeboard" boats get a third of a MPG at 11 MPH. And the don't care.
Perfect timing for this video. I’ve been restoring a 2003 Proline 22 Bay with a 2004 Yamaha SX200TXRC and sending the Yamaha gauges to Gauge Saver is on my list. I am just now starting to dial in cruise speed and prop. I don’t believe the Yamaha gauges provide fuel burn numbers. Cruise is somewhere in high 20s to low 30s mph with the stock prop. She runs 35 mph at 3500 rpm. Haven’t had the chance to run her up to WOT yet. Thanks for the video, it will be very helpful in the coming weeks. #gaugesaver
Congratulations @Kevin Morgan! You're this weeks winner! Shoot us an email to aaron@bornagainboating.com and we'll get you in touch with gaugesaver.com to get your gauges redone! Congrats!
Born Again Boating thank you very much! I believe I’ve responded correctly...hopefully 🤷♂️
Yup! You're all good!
I have seen multiple engine brands going diesel and with great fuel consumption, could you do a video on diesel outboards?
Haven't gotten our hands on any outboard diesels yet :(
Like your car; stats show that in cities; stop and start repetitions use 33% of a vehicles fuel.
In Europe where gasoline prices are extreme comparatively speaking, the "Round About" intersections employed seriously reduce fuel consumption.
Jack Rabbit take offs in boats as well as cars use lots more fuel.
Tire pressure too.
The boat configuration hull type, the prop type according to purpose and a well tuned and maintained engine, reduce frowns at the gas pump.
Getting your boat "Up On Plane" reduces drag, but with an appropriate Hull to Power combination can be done in a gas conserving practical way.
Boating is Happy Time, whether we are flying down the lake or trolling for our favorite fish.
This demands dependable and reliable and cost efficient.
But in general, poor gas efficiency is often a maintenance issue.
The Number one Priority, was and always will be; Safety.
At times; Other people's Lives are in your hands.
Have the bottom of your boat periodically cleaned. Growth will cause drag going through the water also.
I agree totally, I keep the bottom of my fiberglass boat cleaned and waxed and the difference in Fuel economy will amaze you by just this one detail, also keeping it waxed will help keep buildup away from the Hull.
You sound like the How it’s Made narrator/host. I always feel like I am being educated :)
Thats a good thing then :)
My Mariner 150hp still looks and runs as new. Lightly used, fresh water mostly, lives indoors. At WOT, it still goes hard. Will outlast me.
I really like those Mariners, take good care of it.
Just bought a 1980 Silverton; oh boy.
My boat is a 1970 Hartley Vixen with an 87 Chrysler 100hp engine. It's both slow AND expensive to run 😂
19GPH * $4.68 per gallon (What I saw it costs at my favorite place to eat that also has fuel on the lake) comes to 88.92 an hour! That is incredibly expensive!
Try gas at $6.25 per gallon
Not a power boat guy but does it ever make sense to shutdown engines during econ-cruise? I've seen 6 engine plus centers and cant imagine you need all that motor to make econ-cruise speed.
My new boat I have no idea yet still has not been delivered from the manufacturer. My old boat was 3500 rpm at about 25 to 28 mph.
I cruise around 55mph, sea vee z bay boat powered by 2 mercury 250’s
21 Contender with a 250 Suzuki has a sweet spot between 3500-4000rpm 30-35mph with a top speed of 46-47mph
Buck Creek TV it depends on the boat. Mine at 3200 makes 40mph on a 21.
Sportsman 19ft Island reef with a mercury 115 four stroke set high running a solas titan Hr 4 blade 19 pitch.
On a light load she cruses at 26mph @ 4000 rpm burning 4.2gph. WOT = 45mph @ 6200 burning too much fuel for me to look at 🤦🏽♂️
Watching this post I was hoping for a magical solution for fuel consumption as petrol here in Hong Kong is Us$ 8.7 per gallon 🤦🏽♂️😭, but apparently I’m already covering most points to help with my fuel consumption. Still a comprehensive rundown on fuel efficiency.
Great video, mind dropping a link to that fuel gauge/ meter? Thanks!
Thank you! Sure here: www.amazon.com/gp/product/B000FQ01TE/ref=as_li_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B000FQ01TE&linkCode=as2&tag=bornagainboat-20&linkId=4df8bc952af5a75cd87220b85b445ee4
Will definitely have to play around more with my optimum cruise speed. Thanks again for another great Tuesday.
great vid - I cruise @ 26mph - single Zuke 140 - 19 ft cat
My valiant 600 with 2x50 hp 2 stroke is at 35 knots with 30l / h. excellent video from france . Bien joué ! # GaugeSaver
That looks like an awesome rib!!
My 2006 optimax I just bought I inslalled them borh the same way. but when I star them up the left one works just perfect, but the other one rpm goes up to 1800 and wont go down. I change the Throttle Position sensor and it keeps doing the same. before I bought them I tested them and they were great don’t know what’s going on with it.
Make sure the throttle plate is shutting all the way, other than that its hard to say
If you have a twin counter-rotating install, then apart from using a LH prop, does the whole engine turn backwards, or is it all handled with a modified shift/cable linkage?
Engine turns same just reverse gear in lower unit
but when the fuel tank is full you won't get that best fuel burn. My old boat had 1000 ib fuel capacity with a 1000lbs of fuel onboard planing would take wide-open throttle to get up on top. But I could cross the great lakes and come back without refueling.
Awesome content! Any vids on parking a trailer in a full lot at the launch????
No but that's a great idea!
Simple have the cars towed that have no trailer. I see it alot. 😁
What about jack plates? Should the jack plate be all the way down or should you bring the engine up that way also?
That is the same thing as the trim, so you just have to play with the adjustment and level. It's the same concept though :)
135 mercury verado on 20 ft. Mako. Doing 37 mph top end and 30 is my sweet spot, the fuel is about 1.7 gph. Not bad but still not the best. Still working it out. Thanks for the added information. I will definitely be using it. As for the GaugeSaver they are highly recommended from me. Saved me about $500.00 over buying new ones. Had a pair done by them and did a great job considering the shape they were in. Keep up the good work guys. Look forward to seeing your videos each week Arron. Stay safe! Have a great week.
Hi David Smith
Are u sure ur getting 1.7 Gph. What Rpm are u getting at 30 mph. I’m asking coz that is an amazingly low consumption and my boat isn’t very different than urs but my fuel consumption is more than double of urs. And with petrol at $8.7 /gal I’m trying everything I can to improve my economy.
N M how are you doing, hope all is good, yea I’m pretty sure that the numbers are right. I’m not 100% sure of the rpms at this moment haven’t had the boat out in a couple months with this lock down because of the virus. If memory services me I pretty sure it’s about 3400 or 3500. I think I can do better as the prop could use a bit more pitch but we will see. Anything I can help you with please send me a text.
N M. Just thing, double is quite a bit. What are your rpms? Also what about your pitch on your prop. Just seems like a lot of fuel. There are so many questions to ask. Boat weight, motor size, etc. etc.

So I have a Sportsman island reef 19ft running a Mercury 115 four stroke (the older 1.7L engine but in great condition with low hours).
The boat when running light is around 2250Lb. My motor is set pretty high and I run a SS Solas Titan HR 4 blade with 19 pitch (seems to be the best prop I can get for my application).
I’m very meticulous about my fuel consumption so I always keep track of my RPM, speed and consumption GPH. My boat comes on a plane at 3600 rpm @ 21mph @ 3.3gph, I usually run at 4000rpm @ 26mph @ 4.2gph. At WOT it will max out @ 45mph
I know the new mercury 115 (2.1L) would be about 10-20% more fuel efficient, but I would still be way off your numbers.
I usually fill up only the fuel that I need to keep her light and remove the Bimini top to reduce drag. So I’m really trying hard to maximize my fuel consumption and would consider any tips to improve on what I’m doing.
N M I am running a 135 verado that is spected to run like a 150. I planes out a bit quicker at 3400 rpms and 19 mph. The Mako is a foam filled boat and sits a bit higher in the water than most. Weird though cause she is some what heavier. I would have to look at my papers but I think it’s around 2600 lbs. I am also using a 19 pitch prop though it’s a 3 blade. I am doing the same for economy fuel, water, top down, etc. I don’t run full out unless I have too. Wow 4.2 gph seems high for your boat. I would think that half that should be the number. 4000 rpms at 26mph is the issue I think. You have power trim right? Try that. Bringing the bow up a bit and work on it from there. Keep an eye on the gph as you do this. I not insulting you. You sound like you knee what your doing. But the numbers don’t seem right for the size of your boat. At 26mph my rpms would be about 3200. Guessing right now but about there. At 4000 I’m pushing 30+ mph. That being said the 4000 at 26 mph is what needs addressing. That’s what is standing out to me.
I have a 25' Sport cat with dual 150 mercury two strokes and at 3200 rpms trimmed out it does about 30 mph but at that speed I burn 50 gallons of fuel in 60 miles so she's a gas hog and I need to slow down probably lol. I have to note that I always keep both 76 gallon fuel tanks as full as possible so I'm carrying some weight.
Great video! The editing is on point.
👍🏻👍🏻 love your content
Thank you! If only it didn't take so long lol
Great info
Glad it was helpful!
Nice job!!
Thank you! Cheers!
I have a 2005 F115 Yamaha on my 19'6" Seapro bay boat and I was wondering what's the best to track my fuel consumption? I don't have smart gauges and my Garmin 198c doesn't have diagnostics. Do I need to upgrade? Thanks for the videos btw. Super informative.
Um, without buying a fuel management system and Guage, you can just fill up the fuel tank to full. Then keep track of where you can and how far you go. When you get back, fill up again and write all the numbers down in a notebook. Do that for the next 5-10 times you go out and you'll get an idea of what your burning :)
@@BornAgainBoating ... wait - you mean like math and stuff? 😉😉
Looking forward to finding my sweet spot! I’ll revisit this video for sure!

Wondering if a fuel 's chemical makeup affects gas mileage? Also, wether synthetic oil vs. regular oil lubrication affect milage. Regarding chemical makeup, 10% ethanol seems to introduce problems other than just the mileage of a marine engines. (phase seperation & plastic parts damage etc)
What engine are you running ?? Regardless, buy some Diesel Synthetic, which has additive ZDDP that will make any off-road engine last longer. Go for premium, synthetic oils. Buy Ethanol-Free Boat Gas when you can, and definitely before going "off-season" Or buy "Sta-Bil".
I run with the big boys 6.5kts at 2ltrs p/h 23ft full displacement in any weather lol oh and 30hp diesel
:)
my 21ft toon cruises about 18mph with a top speed of about 34mph. running a single johnson 150 2 stroke. it burns a lot of fuel. My ski has a cruising speed of whatever I feel like and a top speed of 80mph and it gets horrible fuel mileage too lol
Clean bottom making a big improvement
1988 Sea Ray Laguna 24'. 2x200 Yamaha hpdi. 30 MPH 2900-3000 RPM. 10-11 GPH. Too speed 60mph. 38-40 gph #guagesave.
#gaugesaver. Running a Yamaha OX66 250hp. Runs about 40+ mph in its sweet spot. Great boat
.
Is GPS speed more accurate than the engine gauge speed gauge?
Good video, however you should set the gauges to miles per gallon or miles per litre for a good economy number, since you can burn more fuel but gain more speed and results in being more efficient.
Exactly, liter per hour is not very interesting without taking speed into account.
It’s relative to the boat it’s being displayed on. It’s not comparing boat to boat, it’s all relative to the same boat, every time out.
@@jaredmayer3960 Yes, but the numbers are misleading to many, and takes extra math to become meaningful.
Which is the most economical speed in this example in the same boat: 25 liters per hour at 20 knots, or 35 liter per hour at 30 knots?
Yep, its the 30 knot speed, even though it uses a lot more fuel per hour.
No such problems with a mpg or mpl number, all that you need is right there.
No
@@jaredmayer3960 No what? They video is about fuel economy (as is in the title), not fuel usage per hour. With that kind of reply, it would seem you perhaps didnt understand that?
Unfortunately I'm currently running an underpowered outboard on my boat using a yamaha 25 on an old 60's or 70's 16' boat. To save weight ive been using a jerry can instead of the built in tank, only bringing a 4L jug of water+ couple snacks, minimum safety gear, smaller anchor with less chain. Can't wait to repower
25 hp isn't underpowered. I was recently gifted a 61 16 foot boat that has a 25 Mercury on it. It goes quite well. Fast for such a small motor. The motor does have that fin on it so maybe that's what's giving me a bit better speed. No idea as I'm still playing around fishing the season instead of worrying about speed and other things. Fishing is first until winter then modifications can be done. Use what I got as much as possible. 😁😁😎
Gas mileage… we do a lot of wake surfing. We ballast the boat so heavy it’s 1/2 throttle going 10mph. We can burn 20 gallons in a 4 hours on a 21’ boat. Would probably be cheeper to go to the ocean where the waves are free, but I don’t like sharks.
It seems like it is just an add for gauge saver.
