Pulled my boat last night and the exhaust started to blow large amounts of smoke under high torque. Then drove it home and it smoked like crazy non-stop until about 5 miles down the road, then I heard a sound, almost like a small backfire from the exhaust and it stopped smoking, completely :eek:


Today I drive it around and it wont smoke at all. My fluids look normal and does not seem contaminated. It was kind of dark so I could not quite tell the color of the smoke, but it did not smell pleasant, my thought is definitely oil.


Any ideas?

Maybe some oil was getting sucked through the breather in the valve cover into the TB.

Bad PVC on one cover but the other side has a tube that goes right from the cover to the snorkle on top the TB.
