These videos are awesome! As a first-time boat owner, I find them really informative. Really good value!
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)
Hey Geoff, I've heard of coca cola being used to free things like injectors, interesting idea to mix it with a bit of vinegar too. It makes sense that using a mild acid can free something that lubricant alone can't too. I'll be sure to give it a try next time.
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.
Thanks mate, good luck with the outboard.
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!
Thanks mate, glad you liked it.
I'll second that motion, 5 years after the fact! (thanks Dangar!)
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.
Rats ! The impeller was in fine shape, BUT......thanks to your telling me to put it in reverse before I dropped the lower unit, it was simple to rotate the prop to align the splines when it went back on. I did not use the trick of the ratchet strap, but I did suspend the foot with a rope about an inch below while I was jockeying the splines into position.........made it much easier, especially since I was standing in 18 inches of water in a lake with alligators. I am now thinking my overheat problem is caused by calcium buildup in the cooling passages. I will be flushing with a product called called RYDLYME, which seems to have a good reputation. Ever use that one? Thanks for everything!

I have a 1999 Yamaha C60 tlrx 2 stroke outboard and the compression was down to 90psi on all 3 cylinders from 120 psi when I bought it. The Yamaha shop recommended a feul additive callled Ring Free. I thought this was just a sales gimmick, but after using the stuff my compression is back up to 120 pis on all three cylinders. Now I use it regularly every time I add gas, or petrol as you guys say...
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.
You’re welcome. :)
Hands down best video on a 2 stroke outboard
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!
Thanks mate, glad you are find the vids helpful. :)
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
You're welcome. :)
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 (lessons) means even a novice like me can enjoy boating without breaking the bank. Keep up the great work.
Thanks Adam, glad the vids have been helping you.

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.
+GmGarlo You're welcome, glad the vid gave you the confidence to do the job. :)
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.
Thanks Bruce, glad the videos are helping you and enjoy your retirement on the water! :)
Great job on the video. Very informative without being too chatty.
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!
Thanks James, comments from people getting value out of the videos always makes it feel worthwhile. :)
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!
Hi mate, glad the vids have been helping you with your boat. Enjoy your time on the water! :)
Without doubt the best outboard maintenance video I’ve seen, clear and concise, terrific for any boaty, thank you.
You're welcome mate, glad you liked it.
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
Hi Russel. It could be down one cylinder which is giving you the drop in RPM. That could be from water on the HT lead causing it to lose spark or just a bad spark plug. I would start by doing the plug and lead replacement you were already planning and see if the problem is still there.
I meant to let you know that I got tied up scrubbing barnicles and other things boat needed, then quickly replaced spark plugs at end of the day and it seems to be running like a dream, as well as picking up about 4knots with the smooth bum. so cheers.
The Yamaha dealer told me that to replace the leads I have to buy the whole coil as they are one unit. $96 each on a v4. Glad I didnt yank them out. Do you know if there is a way to replace the leads on these without doing the coil.
PS Appreciate the vids, nice to be able to watch good boating vids without a septic tank accent
Thank you. All your videos are great and have finally helped me brake the mystery of marine outboards. I now feel confident working on my old engine and servicing it. Also, through watching you’re previous videos you’ve generously passed on a huge amount of knowledge that will enable anyone to buy a second hand engine with confidence (knowing what to look out for) and to deal with dealership repairs or servicing, especially when getting the feeling you’re having the wool pulled over your eyes or being fleeced, unfortunately this happens from time to time. 👍🍺👏🏻
You're welcome mate, glad you've found the videos helpful. :)
Having recently purchased my first boat I've found your videos invaluable. This video was a great introduction into maintenance of outboards and you provide great explanations and tips. 10 outta 10 pale ales👍👍
Cheers
Thanks Chris, have fun with your new boat!
i just bought mt first boat and wanted to get outboard serviced after watching your video i now feel confident enough to do the work myself. thanks for sharing your expertise.
You're welcome Jimmy, good luck with the servicing.
He made a useful video on making your own pressure tester out of a tire pump with a gauge. I only will use one for my own testing so I chose to get by with a Bell bicycle pump from Academy, for like only 9$ 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.
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.
Thanks mate, glad the video helped.
You've help me a lot. Feeling more confidence in myself, to get an unknown engine running. Thank you very much!!
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.
Thanks Robbie, glad the videos help you.
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
Thanks Anthony, great to have you aboard. :)
Love the straightforward description of what can seen as mysterious. My late father (Dr. Harvey Brown M.D. Professor of Medicine) used to say that knowing how to fix outboard motors (and air conditioners) would let you make a decent living anywhere worth living!
He sounds like he was a very smart man. :)
@@DangarMarine But (of course) I didn't follow his advice ;-)
Weird flex using your dad, but ok
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!
Thanks Andreas, great to hear you've been enjoying the channel. :)
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.
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!
You're welcome Reggie. It is a good point about checking compression as if it is low, no point scratching your head about any of the finer points.
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.
You're welcome Allan, glad the vids have been helping you. :)
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.
That was so informative and helpful. Thank you so much for taking the time to post this video.
You're welcome Tony. :)
nice pointers with the water pump, especially rotor direction
Glad the video helped you. :)
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.
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.
Thanks mate, that's certainly the goal! :)
Brilliant, thanks for taking the time to make this very informative video mate.
Wish I had a mechanic here in North Alabama, USA that was as professional as you are
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!!
That's Robert, glad to hear you are enjoying the vids. :)
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!
Literally fantastic. Thank you for making these!
Thanks Sam. :)
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.
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!
Yep me too that's why I'm here
Man, this is an awesome video !! Thank you so much for your time helping us !!
Thanks David, you're most welcome. :)
Very informative and easy to follow. Thanks for the great tips.
Thanks Mark, glad you enjoyed it.
The world could do with more Dangar Marine's. Thanks for taking the time, bloody legend mate.
You're welcome mate, hope the video helped you. :)
@@DangarMarine immensely! I'm about to buy my first boat and your videos really demystify a lot of the complexity and give me a lot of confidence. Might even be a good topic for a video - DIY diligence for purchasing used motors.
Hope your channel gives you all the success you deserve.
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.
Fantastic and informative video. Well paced and presented. Thank you.
Thanks mate, glad you enjoyed it. :)
Dangar Marine j
Thank you for sharing! Good work!
Excellent video for those of us who are interested in doing our own maintenance. Everything looks straight forward and doable for anyone who has some mechanical ability. I am thinking of buying an outboard soon but I don't want to pay the high maintenance fees to keep it in top shape. You're video convinced me I can do it myself. Besides, the nearest Tohatsu or Suzuki service shop is 20 miles away from me and probably booked solid so do it yourself will be a must. Thanks again for your instruction.
You're welcome mate, glad the video helped you.
Your videos ,are always well detailed and explained ,in a professional simple and straightforward manner,Just the ticket!!!.
Thanks Gerald, glad you liked it! :)
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.
Poo of our old 9oo o
Thank you for taking the time to put together such and informative video..
You're welcome. I hope it helped you. :)
As a first time boat owner (1998 Evinrude 115 ) your videos are awesome !
Thanks Dennis, glad the videos are helping you with your new boat.
Thank you so much for this video and greetings from Finland. Your pedagogical skills are outstanding!
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!
+Ditajobe Thanks mate, glad the videos have been helping. :)
Thank you very much
You're welcome. :)
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.
You are most welcome
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
great video. Thanks for posting and sharing. Cheers
+aabasiry Thanks mate, you're welcome. :)
Thank you so much for this very good and well made video.
Thanks Bernie, glad you enjoyed it. :)
Dangar Marine can you put a three blade prop on a mercury 4.5 it came with a two blade prop.
Excellent as usual. I don't own a boat, but picked up 3 outboards on ebay because of your great videos.
+William Scanlen Thanks William, sounds like you've got a few projects ahead of you!
Got the same yamaha doing a service. Your video save me over $400. That $400 goes into the Lowrance Elite 9 Ti Combo piggy bank. Thanks Stu
You're welcome. :)
Excellent! Thank you for taking the time to make this video. It really helped me.
Thanks mate, glad the video helped you out. :)
great videos. they are very helpful.
Thanks Hector, glad you like them. :)
Do you have a website to see more repairs and maintenance to boats?
Hey Hector, no I don't have a website, but there are over 70 videos here on TH-cam now! :)
Serviced my Yamaha 200hp today thanks to this video. Went quite smoothly! Thanks Stu appreciate it.
Nice work! :)
Thank You for the very informative video. People such as yourself are an asset to the average boater .
Glad it was helpful!
THANK you!
Welcome! :)
u are a mechanic!
New boat owner, your videos have been very clear and helpful. Thanks and great job
You make it look easy thankyou for teaching and showing marine engines yr a legend. ..
Thank You .. Great Vid.
You're most welcome. :)
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! :)
Hey Andrew, always great to hear from another Sydneysider. I'm glad the videos are helping you, I've certainly got plenty more planned. Donations are always welcome, hoping to get some better lighting next. If you go to the channel page there is option on the right to donate directly through TH-cam. See you on the water, Stu.
Awesome, thanks Stu. Do you have a business, or is it just a hobby? I'm just wanting to get my motor serviced, as well as my forward control/harness wiring cleaned up a little (it's currently in a big pile on the floor of the boat). If you do jobs like that, can I bring it in sometime?
Hi Andrew, yep, we have a workshop in Mount Kuring-Gai. Happy to do the work on your boat for you. The Facebook link the channel page has all the company details.
+Andrew Pickles hi Andrew, I saw a message yesterday about bringing your boat in but I can't find it now. Can you give me a call? Details are on the S&A Facebook page linked from the TH-cam channel page.
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 .
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.
+plumbdownunder You're welcome mate. I really hope the videos help you get out and have a great time on the water. :)
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 TH-cam, don't make it Godspell!
Do you mean gospel 😂
@@jeschreindl I say wut I mean and I mean wut I says! :-)
Zac vaper 😂👍🏻
I'll be coming back to your blogs regular very clear and easy to follow I'm making up my mind buy either a rib or a small speed boat but will have an outboard on either 🤔 thanks for your time from the uk 🇬🇧👍🏻
You're welcome Mark, good luck finding a good boat. :)
Dangar Marine thanks have seen a few ribs I fancy just waiting for one that's under a hundred miles away 🙄 noticed the tat on your arm I have a simler one Pisces ?
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!
Dude, you and your videos are awesome. Still helping guys learn 4 years later... Thank you!
Great instructional video, probably the most comprehensive and easy to follow guidance on outboard servicing I've viewed, thanks!
Thanks Paul, glad you liked the video. :)
I subscribed. I really like your practical approach to mechanics. Reminds me of my old man.
Watching your videos actually gives me a bit more confidence in my old outboard. I was considering getting a new motor just for peace of mind but after watching some of your videos I've decided to keep putting along with my motor.
Thanks mate, glad you've decided to join us. Lots of old motors have plenty of life left in them. At some point they do become more trouble than they are worth, but if they are treated well they can do for decades.
I tried to change the grease in my outboard. The tilt function of the tiller arm is getting very hard to move now. I was able to put fresh grease into the nipple for the steering section. I'm unable to pump grease in to the tiller arm tilt or the motor tilt. All those areas have some corrosion. I've purchased a zerk mate tool to try and clean out the old grease.hopefully it gets the job done.
Also I put grease into the wheel hubs on the trailer. Old grease came out the front of the first wheel but the second hub the spring tension on the hub maxed and then grease poured out the back seal. Should I just replace the hubs in your opinion?
I’ll never forget having to change out my water pump in my 87 Johnson 140. There is a hidden screw under the carburetor that releases the gear shaft. What a pain. I finally came up with a trick to replace it. The tube didn’t exist back then, google brain had to be used.
Yes, quite often gear selectors are tricky to get to on outboards.
Thankyou, really informative. I want to have a go at the pump impeller, but before this I had no idea where to start.
You do the correct things. Well trained and you have retained that training for your clients.
10/10!
+alectraproject thanks mate, glad you liked the vid. :)
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.
42:20
As an American didn’t realize would have to put k’et’tle on for this but makes quite a bit of sense
Tremendous video brother 🙏
Huge fan
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.
Glad it helped. Have fun!
I really appreciate seeing how you did the service on this. I've been fascinated with watching your videos over this year (2020).
Awesome! Thank you!
THE best video on servicing a 2 stroke outboard, thanks a lot mate 👍👍👍
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.
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.
I am a new subscriber from Pennsylvania, USA. Great job on this tutorial. I will refer to some of your maintenance tips for this Spring boating season. I believe my thermostat may be why my 8hp Honda kept stalling after running for 5 minutes.
Thanks mate. You can get a cheap infrared thermometer to confirm if your engine is stalling from overheating.
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!
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.
You’re welcome mate, glad the video helped.
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!
Thanks buddy. I’m servicing my bass boat that’s been sitting .
Very comprehensive video, you where lucky how easy that lower end came out. When they get stuck you have to pry the engine off the driveshaft, hammering on the skeg to free it will end in damage.
+alnbaba Yes, it's amazing how big a job can become if something is corroded in place, and you are dead right that if you aren't careful you can end up breaking something and making things even worse. It's always a bad day when the powerhead has to come off just to change an impeller!
Very educative in a clear and concise manner. You are a brilliant engineer!
I'm picking up my first engine tomorrow that's in "running condition" for 300 canadian pesos. A mercury 9.9hp. Now I know all or most of the questions I need to ask when picking up the engine. I also have an idea of the labor that will be involved if the seller has none of the answers. Thanks a lot from up north!
Hey Matt, good luck with the new motor. I hope your pleasure to peso ratio is a good one! ;)
