1993 Evinrude 30hp... I just bought old Lund fishing boat and when I changed the lower unit oil old gear oil came out was green at first then near the end of the draining a bunch of thin black oil suddenly came out... I am not a mechanic by any means... no visible leaks. Looks like the black oil that comes from the exhaust after running with a hose and earmuffs. ?
I'm guessing I have a problem with a seal? Please advise. Thanks.
