If I am not mistaken, the Tohatsu 2 stoke motor has its main exhaust through the prop? If so, it would seem my oil problem mentioned in another thread today would be from the intake system, cause when I lowered my motor just now a small amount of water with black oil in it, exited the prop opening.

If the exiting "oil" through prop is gummy and oily, it's 2 stroke oil leftovers from combustion, this is normal on 2 strokes engines specially if running on barrels at slow speeds for long time periods. Minimum when running at sea, lake specially at wot when engines cleans itself through exhaust..
