Hello all! This is my first post after hours of lurking around reading tons of useful and informative info. I should start by saying I have an 87 thundercraft regency(which was a steal, more or less free), with a Ford 2.3 and the omc cobra outdrive. I can't say it was full of problems but was very neglected so I am fixing things little by little. It runs good and shifts great, but since the boat is almost 30 years old, of course seals go bad.

I removed my outdrive after I winterized it so I could inspect the bellows and noticed the exhaust bellow is cracked and the u-joint bellow is full of grease(which is good)and or gear oil I think. It's really thick though, like I scoop it in globs. I will attach pics of both the bellow and the input yoke. I was thinking the oil seal by the input yoke has gone bad, but I am new to boats so maybe it is just grease. If it is just grease, I am going to replace all the bellows just so they're new and done, but if it's gear oil, when I replace the oil deal do I need to replace the input yoke as well?

Any help is greatly appreciated!

Thanks,

Justin

Grease fitting on the side of the transom mount.
​It feeds into the gimbal bearing.
​Like Bondo says the extra grease is from the PO doing his job.

The Ford 2.3 was only used a short time.
​Therefore the parts are scarce or non-existent !
Double check the manifold before you dump a bunch of $$$ into the motor.

The new manifold is rare and if you could find one they are usually expensive.
Saw one on e-bay for $1000 a while ago.
​Some are cheaper?Used starts at $300+
