    Overheated F25, water in oil now - What to do?

    Thanks man. I found and revived my old post on this. Figured it's better to keep it all tracked in one post.

    F25 Bogged down and somewhat siezed up on the water.

    An update on this. The shop didn't do the most thorough job in the world. They said they checked compression, but they did not. I took it out on the water and ran it. it ran great and smooth for about 15 minutes then it started to lose power. Didn't like to idle either. I got back in and...

    Is there a way to determine which without pulling it apart to check?

    Overheated F25, water in oil now - What to do?

    Hey guys. I had a previous post about my motor. The impeller failed, the motor overheated and didn't want to run. At the time, there was no water in the oil. I took it in to a marine shop that specializes in Yamaha. They did the following: Replaced impeller and housing (melted everything?)...

    The shop did that all. They said it runs fine. But it's leaking a drop out of the headgasket. As mentioned, when I asked them about me just pulling the head and milling it at a machine shop and installing a new headgasket to fix it, they said it can't really be done due to a lack of tolerance...

    The boat was only ever started in the water. Last year to winterize I used a hose with the little clamps to run it and winterize it. This happened the first time I took it out this year, and I didn't think to look if there was water coming out when I first started driving it, but either way...

    F25 Bogged down and somewhat siezed up on the water.

    Got word back from the repair shop today. They said the impeller had torn itself to bits and the casing had melted. They replaced all of that, did new spark plugs and cleaned the carb. They tested the motor for compression and compression was good. They found a slight water leak from the...

    Gotcha. Will do. So this was the area that was hot to the touch. I made the general assumption that everything above it would also be rather hot and did not do any detective work on that one :) Is there a seal that has let go allowing the gear oil to go into the water pickup? Or would that be...

    I have not done anything to this unit other than doing the regular oil changes as necessary and the gear oil every year, along with fogging the motor at the end of the season. Boat has only sees about 5 - 10 hours of use per season, but I'm not too familiar with boats. Looked over the...

    Care to elaborate a bit on that? Do you mean that my gear oil got compromised and that's what caused my issues? When I pulled it out of the water there was clearly still gear oil leaking out of it after over an hour of paddling through the water.

    Hey all. I'm new to the boat repair world. I've been doing the car world for over 20. I've owned this motor for 4 years now and it's been rock solid. It's an F25, 25 hp Yamaha outboard. 4 stroke. Oil was fresh last year and it only ran a couple of times. Checked it this year and it looked...
