I'm a first time boat owner and don't really know much about it yet. I just bought a boat that I thought was in outstanding shape considering what year it is. So, I take it out for a few HOT LAPS and and a few days later im looking over things and notice some what im assuming is gear oil on the 3 rubber boots in my outdrive and a little bit more on the plate on the inside where the shaft goes through the transom I think theres some U-joints there. Now its not a whole lot just a tiny bit on the boots a liitle more on the inside. Its a Mercruiser Alpha One. Can anyone tell me if I really need to be worried about water getting in the outdrive and doing alot of damage?
