Bud, you are giving us more than you're getting and if I weren't retired and on a fixed budget, I'd patreon you in a minute. The information and skills you are sharing is an absolute gift.
I completely agree, thanks so much for sharing your knowledge
carb and fueil pump were done the tank been clean filled premium gas on my 30 hp mariner still won't start unless l hold the throttle partway .what could be the problem?
Bad fuel or fuel filter, and usually stater, would effect all 3 cylinders, though no filter as was the case could send clogs to some carburetors and not others, as is almost always the case and should usually be checked first to save time. Also, If you remove the plug wires at the upstream end, at the coil, you are far less likely to get zapped, though sometimes they are glued on.
@@marcelcorbeil615 Blocked Idle circuit perhaps - I usually open the carbs up and put them in an ultrasonic bath to remove the varnish from all of the internal parts..Many people seem to think that a rebuild kit always works but actually this does not remove all fuel varnish from the internal parts.

This might be the best video on TH-cam for inspecting boat motors.
Agreed...
Bold statement.
Although I'm jist starting to watch the video .... you have my hopes high and I'm prepared to me amazed
Concur, perfect for the intrepid and budding handy guy, simple, logical, straight forward, very well done!
You have so much knowledge you’re like the Chris Fix of boats… but better. I’m blown away, thank you for sharing and posting this.
Excellent job explaining things along the way! We really appreciate you and your work that you put into these videos!
Nice ! Thanks, learned alot, good production, great pace.
I don’t even own an outboard motor but this was a great video with great explanations.
Kudos on the thorough diagnostic steps. I just used this to get my 1975 Johnson 125hp up and running. I cleaned all the carbs as I found a plugged and failed fuel filter, and 2 bad coil packs. She runs like it did 2 years ago.
Thank you for the time and care in making this video. Best boat videos on the interent. Period.
One of the most educational videos I have ever watched on boating, thank you!!!
Pedestrian-level new owner of a used outboard. I'm just taking some time to learn as much as possible about how these motors operate, basic maintenance, and troubleshooting. This was a very helpful video. Thank you. Subscribed.
Excellent videos!!! I appreciate you sharing your expertise and the concurrent excellence of your camera positioning and explanations as well!!! Thank You!!!
The two dead cylinders have higher compression because they have unburned oil in them sealing the rings better than the middle one.
I was wondering about that! Thanks for clarifying.
Whack those ceramic spark plugs with those steel channel locks! Percussive maintenance, baby!
Not likely; a warmed up (The one that was actually firing) cylinder will usually test tighter than cold cylinders. It should be said that "compression testing" is not really a reliable way to evaluate a rotating assembly. I have encountered many pistons with mangled piston skirts that "pass" a compression test. This is because the skirt/sleeve damage does not make it up to TDC in the cylinder. Leak down testing has been the industry standard for some time now.
@@bengoulding6963 Yea compression testing is a myth unless done in controlled conditions.
Ben Goulding leak down test on a 2 stroke outboard, seriously??? It’s basically impossible, unless you remove the power head ( maybe motorcycle, not boats ) . Leak down test are performed in 4 stroke engines.
Eric you make some amazing videos.....I too am an outboard guy like you and love watching your video. ....I personally love the outboard motors....just picked up a 1987 marnir 50hp with pt gonna see how that 1 runs....motor is spotless...and never saw the saltwater....keep the videos coming I am actually learning alot of stuff from watching your videos....
Good information there Eric, very useful for most of us. Greatly appreciated.
As a shortcut before checking spark by grounding each plug, check each wire with a timing light first (quick and easy but less thorough).
Your videos are awesome. Genuine. informative. Keep it up! I'm a boat newbie and your videos are very educational. Thanks.
Excellent video, dude! I've got a 175 I need to tear into and this gives me some good ideas to try. I need all the help I can get!
I have been watching several of your videos, thanks for making them, I need all the help I can ...
Brother you just save me a trip to the boat shop you are a true blessing thank you and god bless 👊🏽
People don't realize that when cleaned the carbs the small particles came out of the Jets and now runs ok .
The underlying problem was no filter to supply the carbs . Foreign particles entered carbs .
No filter killed it👍👏👏great video 🤠🎣
Cliff Thomas I have a 35hp Johnson outboard, 81 model, starts and runs fine until you open it full throttle, then bogs down some, had it serviced at a boat dealer, run good and right until we got down the Lahr a bit, them bogged out a little and now doesn’t seem to be “opening” full throttle and cutting out a little every now and then, any suggestions Sir??? I carry my 4 yr old son out and don’t wanna chance it with him until I find out a little more. We only have 2 boat service places and they are booked, expensive and they didn’t catch the problem at service, so I’m a little nervous of them now 🙏🏻
Cliff Thomas oh and Thank You for Any help or suggestions and yes Sir I have to use ethanol gas, all we can get🙏🏻
You don't say, talk about stating the bloody obvious.
Very helpful and can't wait to try some things you taught us on my Mercury 115
What an excellent full detailed video. Thanks man!
You really done some great video over the years, have helped me be sharper as well.Thanks...
Another great video! Thank you for your time an knowledge.
Got my attention when I saw two of three plug wires pulled and it still ran.
Thanks for this, I had to double back to see what the actual problem was that you fixed. Awesome video.
What was the problem? I didn't see what would cause #1 and #3 not to fire? He said the carbs and fuel pump looked good?
Excellent run through, Thank You!
Brian Wilson hhhh
I've been flipping boats too. I'm learning a lot from your channel. Thanks so much!
Excellent trouble shooting. I really value your videos. Some of the best I've seen.
Thanks for the tutorial. I am scared to open up the outboard motor. Now, after watching this video, I learn more and hopefully, can trouble shoot outboard motor in the future
tom huynh I’m definitely in the same situation.. lol I’ve never opened my cover for being so intimidating even being handy with machinery.
Love these engine videos bro. You do a good job at diagnosis. 💯👍🏼✅🇺🇸
Great job! Noticed your cooling jet stream was a little weak. Have you ever placed the lower end in a barrel of water add simple green and vinegar into water. Then run engine for ten minutes to clean water side,?
So I learned from you in 15 min what it took nearly 15 years of boating and learning (the hard way) on my own. Granted there was no youtube when I first started doing boat maintenance. This video is short and to the point. And to anyone reading my comment I STRONGLY recommend a fuel stabilizer such as Startron or Stabil.
I disagree. Using stabilizer in any boat engine that might be unused for an extended period of time is a bad idea. It usually gums up the carburetor and fuel lines. To be sure that there isn't any damage all of the old gas should be drained out of both the engine and tanks.
I learned nothing, what was the issue? fuel? Makes no sense.
@@kevinpwoodward well you didn't pay attention then.
No fuel filter, gummed up jets.
I don't trust fuel stabilizer either, only way to make sure you don't have fuel drying out in the float bowl is to drain the float bowls for storage. That way there is nothing to dry out and gum everything up.
Not a fan of stabilizer. Non Ox fuel has never done me wrong.
Good video covering the basics.
Great video. One small point: all gray fuel hose is not susceptible to ethanol. There are different grades of hoses, black and gray. Thanks for a great channel, I've seen almost all of your videos. Keep it up!
Eric!.....U R a Genius my friend, great video 👍🏽
Very informative videos, gives me a tool for my outboard.
Thanks heaps!
These videos are soooooo completely satisfying, especially for boat owners.
Sweet love outboards......keep them coming..
Very helpful. Saved the video for my eventual use.
Thank you for the info I've been working on a Mariner and I think that's what my problem is is the carburetors
thanks for making boat outboards not that complicated - wish I had known that when I had my boats...now a land lover
Coming from a coastal part of PNG I just enjoy watching your videos anytime of the day.
Thank you so much for this video. I'm gonna need it to make sure my engine that has been sitting over 15 years.
Very informative video. I just came across one of those grey gas lines the other day and saw that clear lining inside. I was wondering what the heck that was in there for.
Mate, you are amazing. Love watching your videos, very informative and you match it look so easy...
Great video! Love your channel. Keep up the great work!
Amazing video. This will help me a ton with my 60hp merc
Great video! Keep em coming.
thanks bro.. i just bought a 14ft skiff with a 50hp yamaha 2stroke oil injected.. it was bogging down.. so your video is going to be super helpful in my troubleshooting :) ..
Thanks for another great video. You’re a great teacher.
Thanks for that. I have the same motor. It runs good now, but when it doesn't, I will know what to do.
Excellent instruction and explanations. Well done!
This video was great 👍 very informative and detailed 👍 great job buddy...l start my 40 hp Yamaha every two weeks and keep it running great ,👎 no needs to be working on their boat at the ramp...
Good vid. Been wanting a boat project but have no idea what I am looking for.
Good video mate like the detail of it all .
Great step by step video. Thanks!
GREAT Job !!! That worked out well.
Love the video, thanks for sharing. I recently bought a 95 yamaha 115 and needs work. It bogs when accelerating
Killer video, great one, Thank YOU!
Very nice. Just bought an Evinrude Ocean Pro 150 so this will be useful.
I am learning a lot about outboards from you.
Great video TBG!
Hi Eric, I jut bought a 2007 25hp 4-stroke Mercury with EFI, and took it out yesterday for the first time. It would not seem to go very fast even though it is on a 12ft RIB, a relatively light boat. It struggled to get my buddy and I on plane... took like 20mins but we finally got on plane. Then when we slowed down and tried it again, it never happened.. it just felt like we we going 5-8mph with the bow way up on the air.. just no power at WOT. I also noticed the water coming out of the pee hole was no more than a couple of degrees warmer than the lake water... not warm at all.. and it runs fine, but it seems to not go past a certain rpm... almost like it's bogged down or somehow underpowered. Now I know this same boat would have no issues getting on plane with my '97 Johnson 15hp 2-stroke, but this 10yr newer 25hp EFI merc could not get my buddy and I on plane now matter what we did. It does not stall at any point, which is odd... as that would lead me to think it was a fuel issue... it just simply has not enough power under load. Any ideas what it might be?
Thanks in advance!!
@D Outdoors Did you ever figure out what was wrong with it?
Since 1976 outboard marine mechanic on Long island NY I found mostly fuel , over heating water pumps ,burnt pistons, electrical ignition systems.
Japanese Motor electrical system rarely fail like old Mercury and Evinrude power packs coils.
New age Japanese motors have very small Jews in carbs and any dirt water gum will not come out east like old Johnstone Merc hand over carb to suck out gunk trick.
That fuel line issue got me ...
Nice work Thanks
Small Jews? Do they block the jets with their yarmulkes or something?
Great video.Covers all the basics that anyone can check.I would suggest using a spark checker rather than having the plug resting on the block.
wish2fish, I agree
Dangar Stu says; good job, it's time for a pint of beeeer..👍 Or I assume anyway..😂
Do they even sell pints in Aus - when I was there all I could order at a bar was a "schooner"....
@@rhiantaylor3446 Gday Mate. We definitely do Pints in Aus!
Naaaahh here its Miller tiiiiime 🤪🤪😜🤣🤣🤣 the hell with all that PINT........👎👎👎👎👎👎
What happened to fosters ?
Great video man!!
Tohatsu engines are a very good engine. The Sea Tow operation in Organ Inlet OBX uses two 150hp Tohatsu motors and really puts them threw there paces.
As I used to say about my boats, “If it’s got a transom, t***ies, , it’s trouble! Trouble spelled twenties, fifties, hundreds! I have finally gotten off the trouble, I am finally have some fun money. Great video, thanks for sharing. Gimminie, take care of your RUSTY tools. Keep them in good condition, your life may depend on them.
Very important, when you do carburetor cleaning make sure to check and clean fuel lines, change fuel filter, change the water separator and that the fuel in the tank is clean as well, otherwise you just waisted your time and money
You fixed it but it would be nice to hear what the solution exactly was. Why was the engine only firing on one cylinder when it seems there was a carburetor issue? Just a little recap would be great. You are a really good teacher
Bit late, but in case anyone was wondering. Each cylinder on this engine has its own carb. It is just a lottery which one plugs up first or last. So yes, on a two cylinder with only one carb like an 8 HP or a 9.9 the blocked carb will stop both cylinders from firing, but not on this one.
missing fuel filter + carbs werent assembled correctly and clogged
Good video, well documented. Would have loved to see the carbs before they got cleaned to see what 'not bad' looks like, and what the injectors look like when they are clogged. I'm currently troubleshooting an old 1977 35hp Johnson :]
Those aren't injectors; maybe you meant the jets? which have only the tiniest of pinholes through them. It'd be very hard to show on camera. I hope your "Johnson" is ok by now!
@@hughsizzle Thanks for the clarification. Johnson can run, but due to many many things out of my control, I've yet to get working how I want it.
Great Video! Last year I learned about bullshit E-15 gas. I barely take boat out, when mechanic told me about I thought he was bull shitting me. Was driving me crazy ran at low speed gave it gas it bog down bulb would collapse. 5 bucks a gallon non ethanol now and have to drive 20 miles to get it.
Should of titled E-10 or E-15 gas wrecking old out board motors. Thank you. Had I seen your channel I saved a lot of cash at Marina.
You my Man are a great boat mechanic.
Thanks for the great video!
That’s actually running good for 1 cylinder
mine runs on half a cylinder
@@chronicawareness9986 ahahahaha great!! thats nothing mine works 1/4 cylinder, actually
yeah.. it sounds like a lawnmower
@@chronicawareness9986 What kind of motor do you have?
@@benjigans1419 lol i was kidding =P
Just thank you so much. Just looking for a 2 stroke 30 hp 3 cylinder outboard . Have a 25 hp 2 stroke now
never listen to the client cuz you say the carb was clean before you got it how the gone to put back together the carb with no filter make no sense first step is the carburetor you have to check then first second the gas and compression but you the master keep up the good work I admire you
Why would "you," say "the carb was clean before you got it?" Is the gas and compression, first second or second first? I'm so confused!
Love your videos, and the s2k on tha side... lol I’m a cars guy too... love Honda’s Toyota’s nissan...
Excellent video. Very informative, logical and shows everything .
That's exactly same as my outboard. Thanks foor for the video
excellent break down - thanks for sharing, new sub
Thanks for this informative video.
Searching for a boat here in central fl. You're videos are extremely insightful. Wish you could shop with me haha
Man what I wouldnt give to have that Tohatsu on back of mine! Love those motors!!
Need it filler steer
carb trouble, caused by a old gas line. cleaned up the carbs and its good.
Very good and informative video. Thank you.
Thanks, that was very interesting!
Great video. Thanks.
The hard part in cleaning the carburetors is the re-synchronizing! ??

It was a carb issue. After cleaning the carbs the motor ran great! The missing fuel filter screen allowed junk to flow into the carbs."
Can you clarify how a carb issue restored both missing spark plug sparks ? That I know fuel and electric parts do their homework independently, but unite for the engine to work spot on..
excellent vid and explanation. Would have loved to see you clean and adjust the carbs.
Loved this video !!!
I saw a motorcycle rider on a trail ride blow the carb out with compressed air at a fuel stop - cleaned the jets immediately - bike ran great directly after. Fast way to troubleshoot - blew air down the supply line to the carb.
Hey man, thanks for this video, it helps a lot and I really appreciate it. 👍
That’s a great video, well done and I learned so much! Thank man! Keep up the good work!! By the way what are you doing with these boats once you fix them? I would be interested to see if these are in my budget.
Amazing mechanics Mann, thanks
hey great video very helpful , can you post something about rpm limiter, where is it and how to troubleshoot for it thanks
