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!

[@ralphc8500]

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.

[@Jason.outdoors]

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!

[@beng1357]

Great video, thanks! I have the same engine on my boat here in Australia. Very helpful

[@jb501968]

This is an awesome video. Thank you for going into such detail... you just saved me about $300

[@xristiancarvajal1474]

Great Video! Im looking forward to maintenance my engines soon. Thank you!!!

[@bluehornet6752]

This is an awesome video--thanks so much for posting it!

[@DuzBee]

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.

[@leongriffin8158]

All is well, we will get back into producing the instructional videos again this year hopefully.

[@DuzBee]

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.

[@robertrodriguez4587]

This video was so helpful. I’m a first Time Boat owner, and fill completely comfortable with the services you taught.

[@brianmaurer4264]

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!!!

[@chriswalker4512]

Love this video. My local Yamaha guy wanted $800 for this exact service. Thank you Marine Tech!

[@jaydotson8496]

This was a great information video. No fluff or bs and all important info. Thanks!

[@RayBlanco74]

Extremely helpful video! Was able to do the 100 hour easy myself. Thanks!

[@dwlsml4118]

Excellent video and great job on tutorial. Fantastic workmanship. Would take my boat to you.

[@fostermckeon9504]

Excellent job. I am new to boat maintenance and now I think I can easily handle it because of you sharing your expertise. 😊

[@bobgil3464]

Great video. Good advice on the fuel filter (o-ring).

[@darrelellis3924]

Great video Thank you for doing this for us! Much appreciated!!

[@ryanvogt9723]

Thank you sir! Just completed 100 hr service in a F300xcr

[@juniorvasquez9166]

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.

[@robertjackson7590]

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.

[@pashkoskoda3862]

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.

[@zombiejon]

Learning boat repair, great video. Thanks for posting. Subbed

[@martinschulz9381]

Good video. I always put a little dielectric grease on the spark plugs. They then unplug easily.

[@TideFighterFishingTeam]

You do an amazing job with these videos and I really appreciate them. Do you have a 500 hour service video?

[@mikeperez8]

Great video! been looking for something like this for a while. Thank you.

[@MarineTechTools]

+Michael Perez You are welcome, keep an eye out for our other videos. We are putting these out as fast as we can.

[@thompsontaylor3104]

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.

[@scottwicks1267]

THANK YOU! Gave me confidence to do it myself the right way

[@jahosaphet05]

Scott wicks ehh. Need to take off the side covers yearly and use Teflon thread sealant as specified by the manufacturer. I'm not sure what else he missed. This engine also does not have pencil coils. Impact on a spark plugs even for removal is a no no... Especially if you plan to reuse them. It may be 1 out of 100, but imagine if a hairline crack develops in the ceramic of the plug. You will cause your ass and then pay a shop lots of money to find a simple problem that could have been avoided

[@MeadowsJames]

Thanks for sharing. Very informative.

[@kimseymour8896]

Thank that was good I did not think about the possibility of line around the prop shaft blessings

[@atman5230]

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.

[@jb501968]

great video - thank you!

[@Justacogg]

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.

[@maxipower6932]

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!!

[@Rattletrap2]

Excellent video! Very clear and well done! Thanks

[@murphybrown32216]

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.

[@DiegoVansante]

Nice demo, Thanks for you help. Makes my life a whole lot easier. Great job.

[@truckingc]

Thanks man. 1st time boat owner and I changed out my impeller with your guidance. Now I'm going to try this. Thanks bro

[@rohanakumara5915]

great lesson . thank you very much .

[@tadakhoundov7792]

If you ever have a chance - could you post a video on thermostats change on the same motor? That would be awesome!!!

[@CUONGTRUONG1]

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

[@joekocks7641]

You should inspect the fuel from the water separator by dumping it into a glass jar and check for water and debris. Also use a torque wrench when tightening gear oil drain plugs (see Owners Manual for ft lbs).

[@capt.billmoore746]

Excellent video

[@grimereaper6994]

Thanks for the video

[@fishhunt9874]

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 🤣🤣🤣🤣

[@kenfishnc]

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?

[@InvestorAcademyPodca]

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.

[@liamwindsor5854]

Bob Wilson 100 hr service means every 100 hours, not necessarily the first 100 hrs

[@watchyourlip3209]

awesome video bro! helped me big time

[@vinnyoliveri2669]

your videos are great

[@ducatidon1]

Nice video but I'm a little surprised you didn't check the spark plug gap before installing the new plugs.

[@mannyfdez2529]

Awesome video helped me clear some problems I've been having not to mention saving $$$, Thanks from Fish_D_HOOK_N_COOK

[@nygardenguru]

Great tip throttle open and kill switch engaged for checking compression

[@bwagenberg]

Fantastic detail. Need tighter, well lit closeups in time with your comments. Do you work on Merc I/Os also?

[@brightenupcc]

Brilliant.

[@pcarew24]

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!

[@homerwashington8118]

thank you for the info

[@warhouse1167]

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.

[@AhmedAdly11]

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?

[@SnakeBoy-309]

thank you sir

[@davidspencer565]

Great Video. Do you have a list of tools you use?

[@apackwestbound5946]

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 KZbin 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.

[@ramonvenegas8535]

Thanks you you are awesome

[@Honda1k]

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

[@stevek4546]

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!

[@robmiller3072]

Leon, I am re powering with a Yamaha F225. Is there any way you could post a closeup of the electrical connections on the front of the motor?

[@JoeAnshien]

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....

[@stoweman34]

Awesome vid! Are you using the Yamalube Silicone Lubricant and Protectant or the Rust and Corrosion spray? Both indicate high flammability?

[@andersandersson8529]

Thank you for tour superb video! What size of wrench do you use for the oilfilter? 68mm?

[@Rmoseman1]

To avoid water intrusion, replace the lower case drain bolt gasket/seal every time.

[@bobkoch4927]

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?

[@shanesoifert8519]

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.

[@JT-hi6uc]

Can you do a video for the yamaha f225 dry exhaust corrosion issues?

[@toddbaum5746]

Can you please supply all tools and other gear to buy for this?

[@iwatchyouson]

Awesome video. Great job. What year is this yamaha?

[@Nativtexan2]

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!

[@daveschellie5545]

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?

[@zvejysemigrantas]

Good idea using grease on the bolt threads, but why no form on anti-seize on the spark plug threads?

[@robertcopeland9046]

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.

[@rxplusplates646]

at what point do you replace the water pump impellor? Great informative video.

[@Max-kw4px]

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?

[@Rmoseman1]

How much oil does pumping it vs pulling the plug leave in the gearcase?
