I have oil leaking onto my propellor on my Yamahah 9.9 2 stroke from the lower unit. I'm gonna call Copper's and talk to them, but wanted some advice on the subject. This is my first gas engine, so my knowledge is pretty thin. Thanx for any advice.
Take a good look at the oil drip. If its very blackand sooty, it could be from too much oil in your fuel. It doesn't grt burnt and collects in the exhaust tube, then dripps out when the motors sits. Had same problem on Evinrude 90 SPL.
If oil is very clear and clean then thats another problem.
