How to service an outboard motor 

Hands down best video on a 2 stroke outboard

These videos are awesome! As a first-time boat owner, I find them really informative. Really good value!

simple plain video for everyone to understand, clear voice no silly talk and calling stuff by silly names..... one of the best people to watch on youtube for any advice on outboards... if all boat shops worked like him there would be a lot less boats breaking down...

I have an old 88 bumble bee bass boat that has been sitting for a long time. I’m going to go thru it and get it ready for the water now that I actually have time at home. Thank u for this video. This is by far the best outboard motor guide I have found thus far.

That was so informative and helpful. Thank you so much for taking the time to post this video.

This video is great! Lots of good information. I actually have mine partially torn apart for maintenance. I'm waiting for parts. Thanks for posting it.

I just got a Ranger 395-vs with a Evinrude 225 V6 that hasn’t ran for 12 years and thanks to your video I know where to start. Thank you very much

This is probably now Yamaha’s official service training video, thank you, the info provided here will allow my engine to be running for years to come.

Legend! Love your channel, so many great tips and how-to’s; Thank you so very, very much for taking the effort to make all of these excellent videos of yours. You helped me tremendously in so many aspects re marine and associated maintenance, I fail to express my gratitude beyond this. Go Dangar Marine!

I just want to thank you for your videos; I find them very helpful and informative. I am a DIY guy in Michigan, USA running a Yamaha 50HP. I have learned a bunch from you!

Without doubt the best outboard maintenance video I’ve seen, clear and concise, terrific for any boaty, thank you.

10/10... This videos absolutely gold and illustrates good maintenance & service program. Simple to understand with easy to follow instruction. Thanks so much for investing your time to help to ensure we stay safe on the water - really appreciated.

your videos are fantastic. Simple and easy to understand, I look forward to your posting for guidance 1st when i have a problem. Thanks for sharing your experience and info.

Hi Mate, great video thanks for the time posting. I am mechanically minded but this step by step video helped me understand much better. Thanks again. Regards Brook Oyster Bay NSW Australia.

The world could do with more Dangar Marine's. Thanks for taking the time, bloody legend mate.

Dude, you and your videos are awesome. Still helping guys learn 4 years later... Thank you!

Literally fantastic. Thank you for making these!

This is the best video I've seen on servicing a 2 stroke outboard, mainly because you are an excellent teacher! Glad I found this, even if it's from 4 years ago. Well done mate!

I really appreciate seeing how you did the service on this. I've been fascinated with watching your videos over this year (2020).

Thank You for the very informative video. People such as yourself are an asset to the average boater .

i was uneasy to change my waterpump, but after seen your video and how you went through everything step by step was just super. I am ordering the parts today THANKS.

I've never commented on a video before but feel completely compelled to this time. You're absolutely brilliant! Very clear and informative. I'm learning an enormous amount from you. Keep them coming!

The demystification of the outboard motor continues.So interesting.Thanks.

Thank you so much for this video and greetings from Finland. Your pedagogical skills are outstanding!

Very informative and easy to follow. Thanks for the great tips.

Having recently purchased my first boat I've found your videos invaluable. This video was a great introduction into maintenance of outboards and you provide great explanations and tips. 10 outta 10 pale ales👍👍 Cheers

Great job. As stated below you make things easy to understand for the non-mechanic boater. I have a 15 HP Yamaha 2 stroke so the engine in your video appears to be very similar to mine. Again, thanks.

Great instructional video, probably the most comprehensive and easy to follow guidance on outboard servicing I've viewed, thanks!

Man, this is an awesome video !! Thank you so much for your time helping us !!

Brilliant, thanks for taking the time to make this very informative video mate.

Thankyou, really informative. I want to have a go at the pump impeller, but before this I had no idea where to start.

Hey mate, once again great job. I have a inboard/outboard. But I enjoy watching so much, and I learn or get a refresher course each and every time!!! Again can’t thank enough. Ever in Florida look us up and we will throw a couple on the grill!!

Your videos (lessons) means even a novice like me can enjoy boating without breaking the bank. Keep up the great work.

Thank you. All your videos are great and have finally helped me brake the mystery of marine outboards. I now feel confident working on my old engine and servicing it. Also, through watching you’re previous videos you’ve generously passed on a huge amount of knowledge that will enable anyone to buy a second hand engine with confidence (knowing what to look out for) and to deal with dealership repairs or servicing, especially when getting the feeling you’re having the wool pulled over your eyes or being fleeced, unfortunately this happens from time to time. 👍🍺👏🏻

Your videos ,are always well detailed and explained ,in a professional simple and straightforward manner,Just the ticket!!!.

Thanks a lot for that video! Its a great help for an amateur like me - now I will maintain my outboards all by myself! That will spare a lot of money and the my understanding of the technique of that engines is much, much bigger than before! Thanks again!

I will be attacking my first lower unit on Yamaha 50 2 stroke in 2 hours. I think the impeller is shredded. What a great help this has been for me.

Thank you for taking the time to put together such and informative video..

Absolute legend! Just got my first outboard and shes quite old so looking forward to giving it a good once over before running out on the water - Thanks!

I've watched several of your videos and found them very helpful. One thing I learned, especially working on 2 strokes, is to check compression before performing any other service. I appreciate your taking the time to make these videos and I think I speak for most when I say THANKS!

I live in Costa Rica and last year got a 20ft with a 90 Honda on it. Its hard to find any decent marine mechanics here and still pretty expensive. Im doing all my own work on the boat and these videos have been a serious life saver. I worked on classic cars in the states and working on the boat motor was a good transition for me. I have the 1998 Honda 90 4 stroke and that thing sips gas. Keep up the awesome videos!

I did my time as a petrol mechanic in the early 1970's in New Zealand, I was a car mechanic. Having said that, I have always had a boat since I was 19 years old, and always done my own servicing on my outboards. I just wanted to say that you make very good videos and explain things very well. Just a little tip you may find useful at some stage, I watched your video on dealing with a seized outboard motor, and it brought back memories when I had a seized 115 HP Evinrude one year many moons ago. You are very correct when you say, not to keep swinging on the breaker bar, when you can't get the engine to turn over, as it will only cause unnecessary damage to the bores and or rings. After trying soaking the cylinders with the same liquids you mentioned, and still not being able to turn the thing over, I eventually made up a concoction or mixture of coca cola and malt vinegar. Left that overnight, and presto, in the morning, the engine had unseized. Once clearing the fluids out of the cylinders, as you have very well explained, to prevent hydraulics from occurring and cracking heads etc, the motor fired up no problem. The mixture of coca cola and malt vinegar was about 50/50, but I expect the actual ratio was not at all critical. Hope this may help someone one day. Anything to prevent further damage and to resurrect perfectly good motors. Incidentally, I always wintered the engine properly every year after that. Many thanks Geoff (aka Playdoe)

Thank you for learning a lot about major problems with outboard motors. I can now use my outboard motors more safely and fix small repairs by my own.

Excellent video - extremely useful to anyone wanting to learn about servicing an outboard. Thank you!

great video, thank you so much, now even I (mr not so handy trying to learn), can start servicing my Yamaha 40 hp 2stroke himself!

Awesome, just what I was looking for! I have really learned a lot about marine life from your videos this past year, thank you! Keep up the great work!

40:53 Really enjoyed your instructions. You mentioned that when you take the cover off this thermostat will tear but you meant to say the gasket will tear. Great job.

You make it look easy thankyou for teaching and showing marine engines yr a legend. ..

This is helping me a lot. I'm still learning how to do these things. My grandpa and I have a hobby to flip outboard motors.

Fantastic and informative video. Well paced and presented. Thank you.

Thank you for this video,It has given me confidence to service my old outboard. I know I am going to find some issues as has not been used for 20 years but I have had the compression tested and very good. Thanks to your carb cleaning video I am going to sort those out as they are gummed up.Thanks again.

Thank you for dropping this. I have 15hp 2 stroke Yamaha and my young bloke and I had a crack under your guidance and all went well.

Thank you for sharing! Good work!

Excellent! Thank you for taking the time to make this video. It really helped me.

As a first time boat owner (1998 Evinrude 115 ) your videos are awesome !

You do the correct things. Well trained and you have retained that training for your clients. 10/10!

Thank you so much for this very good and well made video.

great video. Thanks for posting and sharing. Cheers

Thanks for the videos. I just got my first boat and not having any friends who boat makes this experience about learning a bit more challenging. Your information helps me from learning the hard. I will be watching you much more. Thanks again

WOW! I didn't know anything about Outboard Motors until I watched this video. I'm no expert but at least I know what to lookout for if and when I should by a boat! I wish you were here in the States mate! Cheers to you!

Wonder how man THOUSANDS of dollars/rupie/GBP you've saved viewers. Answer: LOTS Thanks for a great video. More confident now servicing my motor.

great videos. they are very helpful.

New boat owner, your videos have been very clear and helpful. Thanks and great job

Have had my Evinrude since 1987, bought new, never paid any attention to it due to it operating perfect but now I can get familiar with it. It is like a new toy for me to rediscover.

THANK you!

Thank You .. Great Vid.

Very educative in a clear and concise manner. You are a brilliant engineer!

Excellent as usual. I don't own a boat, but picked up 3 outboards on ebay because of your great videos.

Thank you very much

u are a mechanic!

As others have noted here, your videos are very helpful and clear. Keep up the fantastic work. I am a lady who can put together an aircraft engine but did not know squat about servicing outboards. Thank You.

Thank You, A very informing video. I recently purchased my first boat with a 55 Merc. Was told it runs fine but will do all this maintenance before trying engine. An excellent tutorial for DIYs.

If it's on the front it will be the air box, if it's at the back between the carbs and the intake manifold it will be a gasket.

Great videos! They've been very helpful in some general stuff on my outboard! I'm located in Sydney also, is there any way I can make a donation? It's been very helpful, and I'm hoping you keep making more videos! :)

He made a useful video on making your own pressure tester out of a tire pump with a gauge. I only will use one for my own testing so I chose to get by with a Bell bicycle pump from Academy, for like only 9$ cost. Then used the fitting out of a gear case oil pump that fits my motor. It was easy to put together and a really cheap way out. And it worked! Saved me a seal job, which I was wrongly thinkin needed to be replaced at the time.

Thank ou very much for your information on servicing an out board motor. I have never done it before. And you teaching is very complete as far as I know. Thank you it will be very helpful for me in replacing water pump thermostat and engine lower unit grease. And impeller maintenance and assembly repair with castle nut and gotter pin. Thanks again.

I totally disagree with you on using grease sparingly on the engine and such. You say because it "attracts dirt". Well there ain't much dirt in the ocean but there is a hella lot of salt...I spray my whole engine with grease and it still looks brand new and it's a 1997 200hp Merc... Go ahead guys and douche that engine with WD-40 or which ever brand you have at hand. Remember...just because you hear it on RU-vid, don't make it Godspell!

THE best video on servicing a 2 stroke outboard, thanks a lot mate 👍👍👍

i just bought mt first boat and wanted to get outboard serviced after watching your video i now feel confident enough to do the work myself. thanks for sharing your expertise.

Great video. Very easy and clear instructions I am looking forward to servicing my own motor now. You make it all appear very easy Thanks

Thank you for your excellent videos, I’ve learned a lot and passed some of it off to my students. They’ve also enjoyed watching your work!

Very good video. Well explained and detailed, yet without a lot of excess information. I'm looking forward to seeing the others you have made.

Thank you very much..Im getting wiser daily from your programes

THANK YOU! I am looking at buying a 1981 boat and 35 hp, pull start Evinrude, as I am retiring in just two more weeks. I now have a much better understanding of what to look for when buying and the confidence that I can do a lot of preventative maintenance myself, especially replacing the impeller. You really helped me a lot. Kudos and keep posting please.

I’m 10 mins in And, so impressed Thx bro🙏 Expect this will not be last I watch whole video

Thanks mate. I hope you get the support to make many more. Your a champion!

Great video, Thanks so much for the easy to understand tutorial, not all of us are very mechanical minded like other presenters must believe we are.

Love ya work stu. I just bought a 2003 marina 30hp outboard so this video will help me do my first service on it.

Thanks Stu your videos are awesome I'm learning a lot from you and I have been working on my 1989 Quantum fish and ski boat again thanks for all the great info

I just came across your channel. Thanks for sharing. I have a 28hp (2-stroke) Yamaha outboard motor which I bought, new, in the mid 80's and which is still running. I'm enjoying the content that you put out. Regards from S Africa

Very good video. I'm a newer DIY person when it comes to engine work. There is a similar outboard to your example that requires service before I put it on a boat. Your video is very useful to my tasks at hand.

Thanks for this video Stu. It was really helpful in assisting me to service my outboard for the first time, successful! Love watching your videos.

Serviced my Yamaha 200hp today thanks to this video. Went quite smoothly! Thanks Stu appreciate it.

Thanks for this comprehensive video. Off now to look at my under the cowling fuel filters.

Fantastic video, everything is well explained and easy to watch and follow along with.

Ive had many boats over the years , I have lots of mechanical experience , bikes , cars and boats, but i like watching your work. I believe there is always something to be learned and this is well presented , easy to watch , easy to listen to , and a good video all round. ,,,,,,,,,,,, I was looking for a descent video on adding an electric starter to my yummy 30 hp 2 stroke cv model . I enjoyed watching this anyway , thanks .

These are some great videos you’re making, I understand cars really well but was completely out of my element with outboards until I watched your videos. Thank you for the information, from your USA 🇺🇸 fan.

Well done Stu, plenty of useful and relevant info as usual, look forward to the next upload.

So much information in a clear way to show and explain. Tks Sir.

Hey mate. I just bought a 2001 Qinnie Spirit, Yamaha 130 2stroke about 4 months ago. She has 400hrs, but sat quite a bit before I got her. Im pretty green to power boats, but loving every minute of it. I keep her moored in Lake Macquarie and spend all my weekends out there, even sleeping on her a lot. I have been watching a lot of your videos, and finding them both helpful and easy to understand, keep it up. This morning I woke up in the middle of the lake, kicked the moter over and let it warm up while pulling in my lines , and anchor. Then started heading over to a nearby wharf so my little four legged first mate could empty his bladder. I noticed a couple of coughs, which wasn't unusual, as Ive been planning to replace plugs and leads in the hope that this will be rectified. So I layed the throttle down hoping to clear her out a bit, instead it kept coughing a bit and topped out at around 4000rpm instead of 5500rpm. She did settle and start running a bit smoother but still only 4000rpm. We got a fair bit of rain last night and although my wife got quite wet on her side of the boat, I'm pretty sure we got no water into the fuel system. So I pulled her out of the water and onto the trailer for the first time today.I plan to do plugs, leads and compression test. Then fuel filter, general check over and maybe even pull carbys off and clean out. See how that goes. I would really appreciate any advice you might have on my potential problem and how I am planning on attacking it. Thanks and keep it up
