Good video. Just a suggestion...Whenever I pull spark plugs, I turn them out about one or two turns. Then I use compressed air to blow out the crud that accumulates in the hollow area, around the spark plug hole, especially when plugs are oriented vertically. That way there's less chance of knocking loose crud into the cylinder when reinstalling the plugs.
If you don't set the gap on the spark plug, you get what some one may have dropped on the floor, or the standard gap which might not be for your motor.
I can't say enough how helpful this video is. I have been doing my own service on my engine for about four years now and always revert back to this video for a thing or two. I have also seen other video's of yours and then are spot on just like this one. Thank you Tyler. I really appreciate you!
Great video,,,, I use a good synthetic marine gear oil. It will take more heat and for a longer time when you forget to change it often enough. Update; 2/27/24 I went through my LU and installed the seal with the spring on the inner seal facing the oil and the outer seal facing water. Some of these units lose oil for no reason as mine did when I originally bought it used. This video shows low oil in it and what caused it to burn Black. No telling how long it was run low. Since I changed the seal I changed the oil once and it was full with clean oil. Good Luck.
Great video! One question......I didn't see you do anything with the water pump. I used to have a 2 stroke Mercury and I typically changed the rubber impeller every 2 to 3 years. Shouldn't this be something to do on a 4 stroke as well? Thanks again!
You can’t imagine how awesome this video is, excellent footage and angles, good commentary / explanations. I was sad to see you haven’t uploaded mechanical videos for a long time, I hope all is well.
Leon Griffin I’m glad you and you’re team are well. I would love to see a video on prop shaft seals ect. We really enjoy mechanical videos and your team seems to produce them well.
Don’t EVER pull plugs out with an impact anything!!! Loosen plugs by hand ALWAYS!!! Especially if your boat has been in salt water!! Great way to strip, or break a plug that’s stuck. Bad info!!!
I noticed on my Yamaha engine the filter stands up with the bottom being the part where you unscrew it. That’s different than this filter which is horizontal. I’m guessing different years of different designs. Well done video thank you.
Sorry, just to preface my earlier comment, new owner of 2006 Yamaha four stroke 150 and would like to do it myself. Watching your video and hope this can help me to do it myself rather than taking it somewhere to have it done ($$$$$). Thanks for your help and video.
Absolutely PERFECT tutorial. Any chance you can provide links to the replacement parts, filters or part numbers, in the description at some point? I finally have another use for my flex funnel!!
Thanks for the great video. I noticed when you were pumping in the new gear oil that it was exiting a little chunky in the beginning. Were those air bubbles?
Good video, I'm just a bit taken back by the fact that 100 hours ended up with a skeg with no paint on it, corroded screws on the lower unit and black oil. That engine was ran hard with minimal maintenance, good thing you ended up working on it before it got much worse.
Great tutorial brother!!. I had the fuel filter electric water sensor on my 2015 Yamaha 60hp. Instead of pulling the wires off the base of the bowl, I cut the 2 harness zip ties and disconnected the wiring at the green Molex connector. Push in on the center tab and pull down. I just felt like the wires didn't want to come off the base of the bowl so I avoided that problem if the wiring broke off.
very good tutorial service. thank you very much. if you happen to have a video how to replace the timing belt on that yamaha four stroke 3.3l please let me know. thanks again
One of the best DIY videos, he shows you all the steps he talks about. I hope he makes one on how to change out the water thermostat and engine Anodes on a f225TXR. Also on how to adjust shift/throttle cables on a single shift lever.
What about the engine anodes? Those are 100 hour replacements aren't they? I understand there are 16 on an engine. At least for a 4.2 liter 250. I know the impellors are every 3 years.
I like watching videos about boats. Whats so bad about watching a video about a boat I dont have? Since you two are unfamiliar with sarcasm I shall close the register.
Attempted to change the oil today and as you said, first thing out of the hole was about two table spoons of clear water and I don’t think enough oil came out compared to the other motor. Next step, get a pressure tester and see what’s going on. This will be interesting to see as it is my first time working on these engines.
Hi, maybe you have any video about changing engine anodes in 115 yamaha? on all engine shem I can finde just 2 but on my engien I found 4 :) how that comes??? :)
so too lazy to undo oil sump drain plug and check for any filings on the magnetic plug !!!! also too lazy and cheap to spray in some decarb treatment like ring free to the plug holes.... now for the 100 hour service this should also of had the water pump checked visually ( and changed) nobody can ever say a water pump impeller is perfect without actually looking at it. ive had soem last 4 yearsand some last 20 minutes.. one little bit of shit can get in there and destroy a water pump impeller..... and while down grease the top of the main driveshaft spline .by checking the impeller you pull down the leg and this also keeps the main drive shaft splines from welding themselves in. its a major problem with outboards due to lack of service in this area. even if your not going to drop the leg compley , then at least undo the gearcase bolt and lower it down an inch so the drive shaft spline has moved enough to keep it free in the future.....
Thank You. Great video. Now can you do another with the boat in the water;-) ? Is it even possible? I am considering doing the loop with a boat that has outboards and can't imagine how many times I may have to do this....
Great video, just used it as a reference to yearly service my Yamaha 225. So glad I picked up on tilting the motor and flexible funnel, or in my case a heavy piece of cardboard, for the oil filter change. What a mess that could have been. Do you ever use any anti seize on spark plugs?
Awesome video! Have you worked on the 2016 VMAX SHO 150 at all yet? I'd love to see videos on that. I am about to do the 20hr service. I saw this 100HR video and though it was great!
At 1:22, I STRIPPED THIS SCREW. IF YOU STRIP THE SCREW BECAUSE YOU DIDNT USE A BIG ENOUGH SCREW DRIVER AND PLIER, USE A DASCO PUNCH AND HIT IT WITH A LIGHT WACK, IT WILL COME LOOSE AS A GOOSE, GOOD LUCK PEOPLE
Great Video - thanks for all your assistance. Question: for winterization, it was suggested to run an external tank with 2 gallons of gas with Yamaha Storage Fogging oil. Where do I hook up the external tank on an F200xb outboard?
i know this question is very old, but figured I'd answer for other people. The external tank attaches to the inlet of the primer bulb of the fuel line that goes into the engine.
Good afternoon. Do you a 20hr service on the yamaha? I have a new 200hp and it's time for the 20hr service. Your videos are very detailed. If not can you tell me what I need to do?
You did not put any anti-seize on the spark plug threads, I know this is what Yamaha recommends but it seems counter intuitive and I would like to know why Yamaha recommends not to lube the threads. Great video, thank you!
One thing you didn’t mention, I see my maintenance kit came with 2 gear lube bottles. I have no idea how to transfer from one to the other without losing oil
When greasing the steering shaft I always keep pumping until all the old grease is purged out and I start seeing the new grease. Should I not do that??
ONE note: you use a tool to tighten the oil filter, my dad is a car mechanic, and he says, DON'T use tools; this guy IS an expert, he ONLY tightens the filter 3/4 of a turn AFTER the gasket contacts the surface of the fitting!!, if anyone tightens more the filter will break, remember the threads are only made of extruded metal, not cut into cast stock!!
Would you recommend anti seize on spark plug threads? I know NGK says no anti seize for automotive use because it changes the torque values by 25-30%, but I wonder if guidance is different for salt water exposed engines? My hunch is to use anti seize and adjust the torque values accordingly. Curious on your thoughts?
Hi there,im about to buy a 2000 model f100 with 380 hours on. Would you know if there is a big difference in fuel consumption from this model and the efi? And do you know if there is any convertion kit to change it to efi? Thank you
Hi Marine tech tools I have a problem with my yamaha 80hp model F80BET - 6D7-L-1007430 vintage 2007. there is water in the engine oil :-(. I have tried changing the thermostat but it did not help. what might be the cause of this problem greeting Jens
Just bought a 5 yr old boat with a 2015 Yamaha 300 with 85 hours on it. Guess what I am going to be doing really soon? Thanks for the very helpful easy to follow video. My only negative is that you did not show the prop attachment removal process, only you denting the prop 🤣🤣🤣🤣
Tyler, you briefly mentioned in passing while you were servicing the spark plugs in regard to their associated valves and cylinders “de carb” (de-carbonized). Would you please either explain more about that process or point me in the direction where I can get good information on the subject. After watching you and Danger Stu on UA-cam for a year or so I enrolled, part time, in a marine tech program to get some formal training (and enjoying it). As a side project in class a “customer” brought in a 2016 4 stroke Yamaha 50 for “service”. The motor is regularly used but at low speeds, it sits on a tender for a sailing club chasing dingy sailboats around the bay. Compression on the top 3 cylinders was > 200 psi. However #4 cylinder was at 125 psi. A wet compression test didn’t help any. All the spark plugs were fouled showing heavy carbon deposits. Bottom line is I don’t know about the next step regarding getting rid of the deposits-how is that done? We didn’t take it further with a leak down test to isolate where the cylinder was losing compression. I have access to Yahama’s tech manuals online through the school but do not see any information on de carbonizing, any help would be appreciated. Thank you for your time.
I'm sure this has been asked , but I am just seeing this video, what is the tool that you use at 12:04 and reuse at 13:58, is that filter wrench? Way different from the car oil filter wrench I'm used to.
You should really check the gap on those spark plugs before installing them! Even if you did gap them you should let your viewers know to gap the plugs. I rarely get to see a set of spark plugs where at least 1 plug is out of spec! Also your drain and fill plugs do not have to be very tight, All they are doing is keeping oil in and water out! I do not suggest amateurs using a impact driver on an aluminum gearcase! Also it is called the spark plug boot that you grab and remove from the spark plug, Not the coil! I am sure you knew this and just got confused but when you are showing other people how to do something that they are not familiar with you should be correct!
Great Video, a real confidence builder for the DIY'er. Regarding water pump replacement, I have a 2005 F150 4 Stroke--should I expect the same difficulty needing a gear puller with the shaft collar in your vid? I have had it R/R every 2 years since new.
If you're worried about priming the fuel to get air out of it after changing both filters just open the drain valve at the bottom of the VTS hit your primer ball several times to push fuel through after you see fuel coming out as steady stream of your VTS drain line tighten a screw back up you're good to go
No way in hell would I use that impact driver on that for lower unit , Great video 👍 Yamaha all want u to squirt 3 shot of oil in each cylinder for correct pressure reading
always screw sparkplugs in with your hands due to cross threading if a spark plug does not go in? check the threads for dirt on the head and the plug. never use compressed air to clean the threads!! due to dirt contamination of the cilynder's use some tape or a tacky cloth
I will remember to turn the wire simultaneously when undoing the fuel filter bowl so as not to damage that expensive to replace water in fuel warning device.Each job to be done was very well explained.Many thanks.
Was watching this and one thing with the secondary fuel filter (what i call the one in the engine that has the red ring to show if water is present) why not just refill the filter assembly or bowl with fuel to keep you from having to reprime the system?
But wouldn't draining the oil from the bottom better allow for any contamination that may be in the system to drain out? Great video regardless and thanks for sharing your knowledge!
Hello my friend I have a 5,30 metre rib and I want to put a secondary motor what should I put 3,5hp or 5hp(note I am from Greece and I don't know very good English)
So if that is say a 2007, and the same person performed the oil change every year that means those side cover screws have never been removed and had thread sealant add to the cover screws. Now the are all going to be stripped when they need to be removed. Not good maintenance.
Can you please supply all tools and other gear to buy for this?
Good video. Just a suggestion...Whenever I pull spark plugs, I turn them out about one or two turns. Then I use compressed air to blow out the crud that accumulates in the hollow area, around the spark plug hole, especially when plugs are oriented vertically.

I thought F200 was a four cylinder
The manual impact driver is an underappreciated tool, better used early to avoid stripped heads.
& the sliding spLïT, [fLat-enD] screw driver😉👌🏻
Who the F would give a thumbs down? This was so educational and informative. Nice job! I should’ve searched this years ago! Dang it
Mechanics
And haters
Probably a mechanic tryna charge $600 for the same service.
This is an awesome video. Thank you for going into such detail... you just saved me about $300
I bet you've have screwed up or seen someone screw up a ton to gain all of the knowledge that you are sharing. I really really appreciate it!

Thanks for a great video
Thanks for the great video.
I noticed when you were pumping in the new gear oil that it was exiting a little chunky in the beginning.

To avoid water intrusion, replace the lower case drain bolt gasket/seal every time.
I've always put pipe tape on the bolt and never had a leak.......
@@nobody46820 tape not necessary... just new washers
@@milkylicker6963 Roger, just thinking if you didn't have new washers. I would use new washers if possible.
This was a great information video. No fluff or bs and all important info. Thanks!
Good video. I always put a little dielectric grease on the spark plugs. They then unplug easily.
Hmm ... I never use a torque wrench to torque new spark plugs. Seat by hand and turn an extra 1/2 turn and you will be good!
Good video, I'm just a bit taken back by the fact that 100 hours ended up with a skeg with no paint on it, corroded screws on the lower unit and black oil. That engine was ran hard with minimal maintenance, good thing you ended up working on it before it got much worse.
Bob Wilson 100 hr service means every 100 hours, not necessarily the first 100 hrs
and now you will be showing how to change a water pump, after the first time you turned it over with no water it was done.

Hi Marine tech tools
I have a problem with my yamaha 80hp model F80BET - 6D7-L-1007430 vintage 2007.
there is water in the engine oil :-(. I have tried changing the thermostat but it did not help.
what might be the cause of this problem
greeting Jens
Just bought a 5 yr old boat with a 2015 Yamaha 300 with 85 hours on it. Guess what I am going to be doing really soon? Thanks for the very helpful easy to follow video. My only negative is that you did not show the prop attachment removal process, only you denting the prop 🤣🤣🤣🤣
Best video on this subject. Very helpful thanks!
Extremely helpful video! Was able to do the 100 hour easy myself. Thanks!
Tyler, you briefly mentioned in passing while you were servicing the spark plugs in regard to their associated valves and cylinders “de carb” (de-carbonized). Would you please either explain more about that process or point me in the direction where I can get good information on the subject. After watching you and Danger Stu on UA-cam for a year or so I enrolled, part time, in a marine tech program to get some formal training (and enjoying it). As a side project in class a “customer” brought in a 2016 4 stroke Yamaha 50 for “service”. The motor is regularly used but at low speeds, it sits on a tender for a sailing club chasing dingy sailboats around the bay. Compression on the top 3 cylinders was > 200 psi. However #4 cylinder was at 125 psi. A wet compression test didn’t help any. All the spark plugs were fouled showing heavy carbon deposits. Bottom line is I don’t know about the next step regarding getting rid of the deposits-how is that done? We didn’t take it further with a leak down test to isolate where the cylinder was losing compression. I have access to Yahama’s tech manuals online through the school but do not see any information on de carbonizing, any help would be appreciated.
Thank you for your time.
Great Video! Im looking forward to maintenance my engines soon. Thank you!!!
I'm sure this has been asked , but I am just seeing this video, what is the tool that you use at 12:04 and reuse at 13:58, is that filter wrench? Way different from the car oil filter wrench I'm used to.
Not different at all. Standard filter wrench, cross reference your filter to get the right diameter and flats.

Don't you have to change the water propeller?
Ugly Dudley impeller^ n only if your deal isn't pissin like it should be, every 2 3 years w saltwater about
Impeller is every 200 hours and on a separate video.
My water pump went at 50 hours. I never got skinny, it depends on the engine.
This is an awesome video--thanks so much for posting it!
Awesome vid! Are you using the Yamalube Silicone Lubricant and Protectant or the Rust and Corrosion spray? Both indicate high flammability?
You need hose pliers in your tools box
I've been a technician for over 20 years and I would never use a impact gun on any spark plug that might be reinstalled you will fracture the plug.
Great Video, a real confidence builder for the DIY'er. Regarding water pump replacement, I have a 2005 F150 4 Stroke--should I expect the same difficulty needing a gear puller with the shaft collar in your vid? I have had it R/R every 2 years since new.
Do you worry about any water in the engine from the cooling system
If you're worried about priming the fuel to get air out of it after changing both filters just open the drain valve at the bottom of the VTS hit your primer ball several times to push fuel through after you see fuel coming out as steady stream of your VTS drain line tighten a screw back up you're good to go
No way in hell would I use that impact driver on that for lower unit ,
Great video 👍
Yamaha all want u to squirt 3 shot of oil in each cylinder for correct pressure reading
How important is the zerk on the lower unit, near the prop & carrier? I didn't see that you mentioned it. F250 question.
always screw sparkplugs in with your hands due to cross threading if a spark plug does not go in? check the threads for dirt on the head and the plug. never use compressed air to clean the threads!! due to dirt contamination of the cilynder's use some tape or a tacky cloth
Why were those spark plugs from the 2 cylinders so much more fouled? Low compression? weak spark?
Thank you for tour superb video!
What size of wrench do you use for the oilfilter? 68mm?
I will remember to turn the wire simultaneously when undoing the fuel filter bowl so as not to damage that expensive to replace water in fuel warning device.Each job to be done was very well explained.Many thanks.
What were the last two parts you mentioned that were chalky and you were going to recommend that they be replaced before the boat is returned?
Was watching this and one thing with the secondary fuel filter (what i call the one in the engine that has the red ring to show if water is present) why not just refill the filter assembly or bowl with fuel to keep you from having to reprime the system?
But wouldn't draining the oil from the bottom better allow for any contamination that may be in the system to drain out? Great video regardless and thanks for sharing your knowledge!
What did he say when he took the spark plug out and they are black because there could be a build up of what?
Thanks man. 1st time boat owner and I changed out my impeller with your guidance. Now I'm going to try this. Thanks bro
Good idea using grease on the bolt threads, but why no form on anti-seize on the spark plug threads?
awesome video bro! helped me big time

Great video, I have the same engine, I am looking for one showing the location of the O2 sensor on this, can't seem to find it.
