- What's the Deal with Outboard Jet Engines?
In this video I go into a few of the details of an outboard jet engine. What is and outboard jet? Why you might want an outboard jet, and why you might not want an outboard jet engine. Outboard jet engines are very specific tools that work very well in certain conditions but not so well in others.

You might need one, but you might not need one.
You need one
damn it , i want one now
Alvin, great info. I have an outboard I picked up at auction I might see if that place in Cali makes one for. I'm not really trying to get up on plane. Heck, I not even trying to go fast. I'm building a tiny pontoon overnighter out of cardboard, 2 part boat foam and fiberglass. Just something lightweight I can load in the back of the pickup and assemble near the ramp and launch. I don't really want much on it in terms of structure. I've found an inflatable tent that I want to use for camping on the water. I do want to make a shade awning and have some chair mounts that can click in/out of place for different configurations, a place to cook and a dometic cooler style refrigerator or just take a cooler....I dunno still thinking about that one but it'll have a solar panel on the awning for fridge, cook plate, tunes, fish finder and phone. I just don't need anything over 5-10 hp. I'm seeing some 6.5 HP outboard jets out of South America but the shipping is just as much as the motor. Do you know of any place that sells just the down shaft and lower unit so I can just go buy a lawn mower engine from harbor freight? That would be awesome.
I called Texas Parks and Wildlife to ask them what would be the procedure for titles for a combination boat/trailer, as in the boat and trailer are one. I just originally wanted to make a boat with retractable wheels. After being shuffled around to different offices they have no clue how to make that happen. They don't seem to understand why someone would want to do that. I guess convenient isn't in their vocabulary. Neither is cost effectiveness. Minus the motor I could've built that boat for the price of the trailer alone....but noooo.....guvment....ugh.
Any thoughts?
P.S. this is a guy, I'm using my wife's account. Mine was deleted for loving the constitution too much. Cheers, Brian
How about dude on his wife’s account? Sounds like him and his cardboard/fiberglass boat needs a channel himself. Shit bud I’ll subscribe to it
Alvin found a way to make me, a strict wade fisherman, interested in different outboard drives. lol
😂
They can help get you to places others can't reach.
Greatest explanation of this topic. Never heard of one until today after 48 years of living. You're the best sir, and thank you!
Glad it was helpful!
In the pacific northwest they're very common with all the shallow rapids in our rivers. Unless you run in skinny water situations they're a waste.
useful, condense, confidence-giving, no-nonsense information
Bro you got some talent communicating your knowledge, you give tons of trust to me and if i was living there in your place I would like you to be the mechanic of my engine. Keep up the nice work
I appreciate that
I love my outboard jet. They are as simple or complicated as you want them to be.
Thank you for this video. I’m getting ready to replace my outboard and this was VERY helpful!
Love my outboard jet for the rivers up here in northern BC.
Best explanation of this seen yet! EXCELLENT! 😁
Glad it was helpful!
Good info. I really learned something. Thx
Glad it was helpful!
Thanks, for all the insight! Great video bro!! I really want one of the hog island boats with a jet engine.
Yeah I love mine.
Great info. I was considering getting one. Now I know I don't really need one. Thanks Alvin!
Glad to help

I always wondered about jet drives. Now I know!
Great explanation, we fish the Missouri quite a bit and run a jet drive and when it gets real weedy in the summer it’s a problem. But as you said you just stop more to clear the intake not a big deal . And in this case the benefits out weight the negatives.
Thanks
Yeah same here, no other way to fish some of our spots.
Need to get a rock ejector and make those grate clearing easier
Very informative, thanks!
Glad it was helpful!
very cool I've never herd of jet outboards
A lot of people haven't. They are pretty cool.
Thanks great video
Glad you enjoyed it
Hi Alvin great videos. Could you do one running a jet out of the water with the water hose connector. Trying to see how to do this.
Great suggestion! Let me see if I can find my hose fitting.
Great video as always AD! Do you have any vids on kayak options or pros/cons?
Not yet!
With a good pocket hull and flotation pods taking off in skinny water is no problem.
Here on the current river in southeast Mo it's hard to find a prop running around. I'm 36 and its been that way since I was knee high.
Crystal clear spring water of about 64 degrees year around.
Fun watching the rocky bottom go by in the skinny areas.
Always thought the naturally cool water was good for an outboard.
I have run the Current River a couple of times. Bought a few motors from Fred over at Current River Marine. Beautiful water!
@@AlvinDedeauxFlyFishing Happy to share the river with ya Alvin.
Always a blast going after walleye and smallmouth next time you get a chance.

I am fortunate to have both a jet and prop
Yes you are!
Love your video.
Thanks!
Our temps are now getting in the 20s at night. Could taking my boat out in super cold water hurt the jet drive motor? After taking it out of the water, I know to trim the motor down & drain the water. Could taking it out in super cold water & in cold temps hurt the jet motor? Also, I store my boat outside with a cover on it. I could store it inside if I wanted to but it would be a real pain. If I do take the boat out in winter, should I store it inside or would this make a difference?
yeah great vid. up in michigan with deep lakes, I had never heard of this.
No need in deep water, but If you want to run some shallow rocky stuff they are awesome.
Own a 25hp Mercury Jet attached to a 1648 Lowe Aura. Total weight is 580 lbs with full tank of gas. Light enough to dry launch off a 6 foot embankment and light enough to wench back up. No ramp needed. Runs 20 mph with just me (175 lbs) and gear down to a few inches of water. Can fish 3 comfortably in water 12 inches or more. Being able to dry launch and drag the boat to the water opens up areas most can never fish. In Ohio you are not trespassing if you are on navigable water. Has also seen it's share of ducks.
Sound like an awesome stealth rig.
I’m thinking about getting the same rig. Do you think this boat would be better off with a 35jet. Boat launches are no issue for me.
Nice video Alvin! I like my jet drive, but agree with your compromises. One other downside I've found is the jet drives are harder to steer at slow speeds. Some of the places I fish have crowded boat launches and I'm always banging into something or someone with a jet drive. It's much easier in my prop boat.
That is true someone else mentioned that.
Yeah don’t worry bout smashing anyone’s else’s boat. Just keep it moving and ignore them as u do so. Hey u just hit our boat. Don’t no what u talking bout there willis but I’m not trying to stop for shit man.

Can imagine these are great for our MinneSconsin lakes. They weedy as hell.

I’m going a little different route. Havoc HJSC is rated for a 115 prop. I’m going to a 150/105 jet. So it should still run decent with a little more fuel use. Surely mid 50s mph
yes

Ola Alvin , adorei seu video ...muito bom mesmo , estou em brasil e os rios aki sao muitos rasos por sua vez , uso uma pequena lancha com motor evinrude 90hp , posso adaptar um Outboard Jet no meu motor ? vc acha que ficaria bom ? onde e como comprar um kit desses ?
Yes, you gotta have one made by a company in Southern California. They’re the only ones that make em.

Alvin... I like your style! Sorry to bug you with a question that only I can probably answer, but here it is. I live in North Idaho. It's a land of deep mountain lakes and rivers, which run shallow in the summer. With my daughter just now turning 13, I have a sense of urgency to get on the water with her (first time boat owner here.) I'm soon to purchase a high quality inflatable (16') which is large enough to accommodate me, my wife, our daughter, and a dog. Plus, it fits my budget and is super versatile.
I'm faced with a decision between a 30hp Mercury outboard prop and a 60/40 Mercury JET, both of which are rated for the vessel and provided as options by the manufacturer, who is based in Canada.
With the help of people like you, I understand the primary differences, and am leaning towards the prop. In the back of my mind though, I see myself getting perhaps bored on a lake and wanting to explore up river (way up river.) I also feel more drawn towards the fast moving water of a river and like the idea of getting away from any congestion you might be more likely to find on a lake.
Fishing is a thing, but not a primary interest. I'm just really wanting to be able to explore, observe and photograph wildlife, do some overnight camping, and without limits whether it be on a big lake, or a river. I'm sure a prop driven outboard will meet my needs 90% of the time. I'm just worried that I might have buyer's remorse if I don't get a JET for those other circumstances (i.e. shallows.) Cost is a factor too though.
Any thoughts? Thanks in advance....

For any one debating on a jet or surface drive, a heads up I have a surface drive and I'm looking to go jet. You can and will shatter a prop in rocks if you use surface drive in them often. Unless your in pure weeds and marsh living on the bayou a jet might be a good idea.

Good viudeo nice to hear the explainaTION VERSAS background music so loud you cant hear what is beingf said Im mainly looking for a fishing boat as in used and I was curious about these jet drive out boards everything has advantages and dis advantages.

Hi Alvin . Do u think that 2x 150hp jet pump engines will push a 25 foot ski boat ? Why does no ski boats use jet pumps?
I think so. It will be like having 2x 100hp engines. The big advantage of the jet is being able to use it in shallow and or rocky water. Probably not somewhere you would want to water ski.
What brand of grease do you recommend for greasing the impeller?
Got this from the outboard jets website - Can you use any other grease besides Lubriplate 630 AA and why do you recommend against using a lever type grease gun?
Any grease of the same consistency (NLGI 2) which is water resistant should do the job. The main thing is to keep grease in the bearing cavity and water out. We prefer a hand held jiffy lube since it does not create high pressure. If a cartridge type lever gun is used, it should be pumped gently! Excessive pressure will invert the rubber seal lips and seals will no longer keep water out.
Nice video. Jet boats sound like they are less efficient then.
Yes they are, you lose about 30% vs a prop.
Last time I took mine out I got a bigger rock wedged in the grate and had it get it out at home. When I did the rock went into the motor. Do I need to be worried and get that out before using again or will it flush out on the water?
It is pretty easy to take the foot off and get it out that way. I have just left them in there, no problems so far, but that's probably not the best thing to do.
@@AlvinDedeauxFlyFishing good to know and thanks for the heads up. I figured it would be okay as rocks and what not get in there naturally but this was a larger then usual.
I have run my jet with a rock wedged between the exhaust and jet nozzle without any problems. You lose efficiency though which could mean the difference between getting on plane in a tight spot or vaccuming the bottom and getting stuck.
Do you know if the same impeller that compresses the water for pushing the boat forward also creates the water pressure for the cooling system?
No there is another small rubber impeller for the water pump. Just like on a prop driven outboard.
@@AlvinDedeauxFlyFishing yep, I doubt the jet impeller creates enough pressure at idle to push it clear up to the powerhead. Mine has a water intake nozzle in the snail chamber that is connected to the cavity under the water pump by a hose. The water pump is the same as an outboard with a prop lower unit. You're in for a rude awakening if you pretend it doesn't have an impeller!
Hey AD! how does that Hog Island do on the rocks? I have 60/40 Mercury
Does great, I think it slides a little better tan aluminum.
be grwàt whél 15 60 hp
Another Con is how much louder the jet is composed to propeller driven
That is true.
I have a evinrude etec 50hp with damaged prop and lower unit it’s on a 15.5’ pricecraft aluminum fishing boat. It tops out at 30mph before I smoked a rock :). Im curious how much performance I will lose going jet. I know you said 30% less hp but with the jet does that mean 30% less performance all around?
#0% less power so pretty much turns the 50 into a 35. But it will run so much shallower.

Very good your video. I was in doubt about buying a 25 hp jet or not. The issue that still inclines me to buy would be safety for bathers, as I'm going to use the boat on beaches. Do you find this question relevant? Hugs
Yes, that is an addition safety factor that people like about jet engines.

So, in most cases, you don't need an outboard jet drive which results in 30 % loss of power, uses more fuel comparatively, needs greater than 25-HP power head. You only need it if most of your boating is in very shallow waters. O.K. Got it !! Great vid.
Yes, exactly

Is a 90/65 Yamaha jet outboard enough to push a 20’ open fisherman by hewescraft? I want to know if I can just convert my 90 or if I have to buy a 115/80.
Not sure, don't know that boat. You will lose 30% of the power by going to a jet so imagine that.

Great video. Low to mid speed control is another con. Once you back off the gas, you are at the mercy of momentum. Jets are not great for anything that requires idling or mid speed. For example, jets can be hard and inefficient to troll with. That’s why a lot of people in PNW will have a second small prop motor (“kicker”). Similarly, they aren’t the best for drifting/fishing and shifting in and out of gear. They have 2 modes -“ON” (wide open) or “OFF” idling to to prepare for going wide open.
Thanks Joe, so true about the "WFO" or nothing aspect of jets.
Hmmm. Ive owned an outboard jet for 3 years and didnt realize there are only 2 positions for the throttle. You should educate yourself a bit my friend. Most of what you said is false.
Nobody should ever leave the harbor or launch ramp without a kicker and a separate fuel source for it. Here in southeast Alaska, kickers have saved many lives including mine when for whatever reason the main fails. The water is no joke and it doesn't care who you are.
This why you swap the prop foot back on in east Tn when leaves start falling😂
On our river a prop just isn't an option.
@@AlvinDedeauxFlyFishing I’ve noticed on your videos. Our trout waters get really shallow and are more or less wading only. Our bass take to deep rock bluffs in the winter. But come spring. Jet’s become king again
Can you swap lower units between prop and jet drives easily/quickly?
It's not that big of a deal to swap the lower units. The hard part is that you need to raise the engine around 5" to get the jet pump at the right height. The jet drive is very finicky when it comes to where it sits in relation the bottom of the hull. 1/4 of an inch can make a big difference in performance.
If you plan ahead when buying a boat/motor combo it’s easy. If you buy a motor with a shorter shaft and a jet pump, you can use a spacer called a bay kit to drop the prop lower unit down to the proper depth. If you already have a prop lower unit with the appropriate length shaft and want to swap to a pump you have to find a way to raise the motor up about 5” like a jack plate or other means.
@@AlvinDedeauxFlyFishing Jack plate would solve that issue
Stupid question for you. How does the Engine stay cool after you remove the lower unit?
Thanks for the Great Informative Video
The jet pump has a water pump for the engine. Works just like the water pump in the prop lower unit. So you have 2 impellers in the jet drive.
Awesome Alvin!
Thanks a ton for the response!
Cheers from Montana.
Actually just purchased a 150/105 Mercury 4 Stroke Tiller. I didn’t think to ask the Guy until I arrived home. Pulled you up.... Saved the Day. Thanks very much
Greetings and thanks for the video information. I just thought of a crucial decision-making question. But first let me give you some entail of the weight set-up/distribution in the boat:
It has a heavy (130 lb give or take) 25 Horsepower Mercury Jet drive 2-Stroke Outboard, AGM Gel Optimum Bluetop cranking battery, and (185 lb) me in the back of the jon boat
The front has a 55 lb thrust Motorguide (about 30+ lbs) trolling motor, two heavy Duracell deep cycle batteries, a 5.5 gallon fuel tank, a couple of anchors (37 lbs total ), etc.
(And eventually I may add front and rear decking)
I thought to put Nauticus trim tabs on my 14 foot jon boat to help it come on plane even better.
But if I install the trim tabs, will the stern/transom be raised too high out of water and cause too much air to get sucked in the intake of the jet drive?? The white caps/big chop I endured last night coming across the main lake doing 19 mph made me think about this!!😆😅
Might want to try a whale tail from the jet dr. first. Get's the nose down and is a lot easier than adding trim tabs. jetdoctor.com/whales-tail/
@@AlvinDedeauxFlyFishing Great idea. Thanks so much!

If I buy a typical prop unit can it be converted down the road? Or would I have to buy a whole new motor?
You can buy a jet pump for pretty much any outboard over 25 hp and convert it.
@@AlvinDedeauxFlyFishingso its less power converting it to a jet?
@@vadimnesen8060 Yes the jet is about 30% less efficient as a prop. So you lose 30% of the power compared to a prop.
You did not mention safety for the swimmers around the stern 🤓
I feel like being able to go anywhere besides dense weed cover may outweigh the downsides.
Does anyone now how they perform on a semi v bottom?
Check this out: outboardjets.com/boat-selection/
I've heard you can get clams stuck in there too 😂
Clams, small fish and sometimes even a turtle! 😂
Have an 18 ft Grizzly Tracker flat bottom and I sheared the skeg off the 60 hp Mercury 4 stroke on rocks in the Delaware River. The lower unit replacement is $2700 as the damage is beyond welding. Thinking of converting to Jet for that money, but concerned over the loss of power. I typically take myself, 2 other people, and my 3 70 pound dogs out; Yes, it is quite a spectacle! Wondering if the loss of power is too much for the size of the boat? The section of the Delaware I am on doesn’t have too much current, but there are some areas of small rapids I need to navigate up. I do take it on lakes sometime, but prefer the river. Any advice on converting?
The 60 should push it, but what you end up with is the power of a 40hp once you put the pump on. Might cost more to get a pump for it.

Whats the plate in front of the intake youve got?
Pushes water to the intake and prevents spray from the foot from coming over the transom.
So it goes good in shallow water but is your in shallow water and stop you won’t be able to take off since you can’t plan it off in shallow water
You can get it back up as long as it's not too shallow.

You can’t compress a fluid … that being said you accelerate the water resulting in a high pressure discharge
True, maybe I should have said pressurize?

@@AlvinDedeauxFlyFishing , thank you sir
How slow can you go with a jet say on the river and still maintain thrust
It will be pushing out water even at idle. How slow you can stay on plane will depend on the hull.
