I have a 1970 johnson 115 hp and it is leaking some kind of oil from the prop, it just all the sudden started. IT's very black and thick. Can someone lead me in the right direction of what it might be?
uradillybar,<br /><br />It is probably from the gunk the Sea Foam has loosened up in the exhaust system.<br /><br />To be sure, check the lower unit lube. Don't forget to replace the fill/drain plug gaskets!
