Hi, first time posting to a forum. Hope this works! I have a 1969 Stamus Fastback with 283 Chevy engine and OMC stringer OD. I've been getting OD oil (type C) leaking into my bilge very slowly for the last 2 years but recently it is excessive to the point that I won't run the boat for fear of burning the ball gear drive shaft. I first thought that it may be a bad housing gasket but from what I've been reading it's probably a gear shaft oil retainer seal problem. The draining oil is clean with no apparent water leakage. Any Ideas?
