I have an 84' Inline 90 and I noticed today while running on the hose ALOT of milky Sut leaking out from prop. I first thought it was the lower Crank seal leaking gas/oil but then pulled the lower unit to see it was comming from inside the megaphone... Could this be comming from the adaptar plate or from the exhaust chest? Or both? It seems to be running great. Is this something that requires immediate attention? Or could I get away with using it for a fishing trip for a week? What do you guys think? Any help would be appreciated. Thanks!
