Greetings. I have an issue with my Tarva, 21' Daycruiser, Merc 260 I/O.
I am getting a milky colored oil coming through a little hole behind the engine.
The hole is about 1/4" round, on the drive right next to the water supply pipe.
The higher the rpms, the faster it comes out.
I assumed I have a seal blown somewhere between the impeller and the drive unit.
I expected to see the same milky color when I drained the drive, but it was just black.
The oil was a little low in the drive, but there wasn't any water getting in the unit.
Any thoughts??
