Oil in transom

[THEFERMANATOR]

FICHT's have 2 oil lines going between the tank and the engine. There's a feed and a return line. Going to have to check them, but if they're original, replace them. You should replace them about every 5 years or so just like fuel lines. As to it smoking, a FICHT engine should be clean pretty much all the time if you're running good oil in it. You are running a DFI oil in it, aren't you? If not, that is a sure fire way to kill one of them engines. Regular TCW3 oil is not up to the task of oiling a DFI engine, and you should really stick with a DFI oil like XD50 or MERCURY's DFI oil for it.
