Hi Guys<br /><br />Just recently I have noticed what appears to be burned oil dripping out between the prop and housing. I assume it is like what you get at the exhaust of a two cycle motorcycle. I am hoping that The Experts can explain it for me. Do I need major repairs or is this normal? This '95 Mercury 40HP, with about 25 hours, runs great on the local TVA lakes. I use it mostly for getting to good flying sites for R/C Model float flying. You cant beat a Tracker Bassbuggy for that. Tks, Bill Miller, Mt. Carmel, TN
