Thanks for showing the carb rebuild in detail. Very helpful!
Absolutely thank you for the feedback!!
Great in depth look at rebuilding the carbs. Thank you!! Makes me wanna check out marketplace for some “dead” outboards.
The crank bearing sounds really loud. Cool video❤
Very loud hahaha. Was also the lower cowling from what I remember wasn’t fully secured so rattled really loud. Appreciate the comment
Nice work, rebuilding the carbs on one of these seems daunting. I’m just venturing into boats and doing my research this is good stuff keep up the great work👍🏻
Great job man.. sometimes you gotta have faith and it pays off.. i got a mercury im doing on my channel now and a yamaha w low compression next.. keep up the vids
Great job as always you are very good teacher btw did you recheck the compression? Chris from OHIO gooooooo Buckeyes
Hey you're tutorial are along the very Best I have the same engine but a 20 hp. Up north outboard Last 50 years if maintained well those yamaha are gem
Thank you I really appreciate that I hope it helped out
Thanks for sharing. I have a 1999 Yamaha 25 with 3 cylinders, found this looking for possible cause of why mine suddenly lost power while cruising at full speed. From 26 mph to 8, all at once. I think it's my gas line, have ordered a Yamaha part, seeing lots of issues around Attwood ones de-laminating inside and blocking the passage. I also may rebuild the fuel pump, which you showed well. Should be rebuilt every 25 years or so, right?
I do have one warning to other Yamaha 25 hp owners - some (including mine) have 5 bolts holding the lower unit. I found another video that showed the 4, followed it and was dumbfounded when the unit wouldn't drop. It turns out that some models have a 5th bolt under the "trim tab", or anode above the prop. Very sneaky of Yamaha to hide that one!
I suggest throwing back those original float bowls in ur carb. The white ones that come with most of the carb rebuild kits tend to swell over time from gasoline and jam, causing flooding and all that👍🏻
Next time try removing and replacing carbs attached to the air box backing plate. You will have to loosen the pull rope assembly but easy all in one piece my friend. Great job
Hey thanks for this comment. I figured there was something like that that you could do but this was my first w these models so just went out on a whim lol. But now I know. Appreciate the feedback!
Okay another great 1
Thanks
I just got this exact engine, cleaned out the carbs. When I start it, it'll run, but suddenly, it'll do something that sounds like a cough with white smoke and squeak like a wheezing sound. It won't turn off, but it'll do that over and over every few seconds. All help is greatly appreciated.
That’s a lean sneeze. You’re not getting enough fuel to the engine one way or another. Basically too much air and not enough gas and they start doing that which they call a lean sneeze. May just need to adjust the carbs mixtures screw and it’ll probs fix your problem
If you take the recoil starter off the carbs are way easier to get off you can just take it all off in one piece
Yea I think someone else mentioned something similar about doing that. Ima be doing that from now on as this was the first Yamaha 25 I’ve done a video for so greatly appreciate the advice and feedback!!!
Good video
Die you also clean the jets ultrasoon?
@@jenp I just used carb cleaner for the jets with a piece of wire to clean them out then I just blow air threw them all
hey man love the videos where can I contact you have a couple question on my engine
I can answer qs on here for ya
I have a 90hp mercury 4 stroke sometime when I go from forward to neutral my engine shuts off or from reverse to neutral but not always thanks@@outboardfinatic
This is completely off topic, please forgive me, I have a 9.9 merc 4 stroke non bigfoot and I was wondering if the tell tale port can be removed and cleaned( area under thermostat)
I mean it can but what’s the issue? If something’s clogged try dropping the lower unit and putting air pressure in the water pick up tube and feel of you can feel air out the tell tale
@@outboardfinatic Thank you once again for the response and help
Salve irmão aqui Brasil 🇧🇷🇧🇷🇧🇷🇧🇷🛥️
I was like.... why are you rebuilding everything on that engine if you don't know if the crank is good.... cuz the crank seems rotten
Not sure why you think the crank is rotten but did everything to make a video for you guys. It was a risk but it payed off. Runs perfectly fine. Never suspected a rotten crank or anything like as normally you’ll hear that pretty quickly. The rattling when it was on the water was the engine cowling. As it didn’t seal the best so it was vibrate unless I put my hand onto it
@@outboardfinatic oh oke i'm not hating my guy... it just sounded like a bad crank with all the ratteling
Yea I understand. But yea it was the cowling it didn’t latch the best. So it would vibrate like crazy with it on. But I didn’t show it in the vid but I could just put my hand on the hood and the vibrating would stop.
No one cares
