351 Redline

Postby arcticman69 » Mon Apr 06, 2020 11:36 am

So, I have a 351FW Redline. I am having issues with losing oil. I had checked what I think is the inspection hole at the fly wheel, there is oil on the cover. Does that mean I have an oil seal out on the shaft? Is it hard to replace? Am very new to this motor. Motor has 900+ hours on it. I live in Bush Alaska, so getting it to a shop is out of the question, but I am mechanically inclined. Thanks!

Lift the motor out of the boat so you can get a good look at it, likely needs a good clean in the engine bay and bilge. Once you get the flywheel off you will find the issue. Buddy drug his feet getting at a similar issue, turned out to be the frost plug on the back of cam. The leak didn't bother him until it blew out and drained the oil. He got lucky and just had to clean the mess and change the plug. The engine is a bit of a pain to pull but you end up happier in the end if you do.

Thanks! Once we melt and get warmer, I’ll do that. Much appreciated.
