You mean that is coming out of the exhaust with engine running ? Looks like emulsified oil . What does the oil in your crankcase (dipstick ) look like ?

Milky

Sounds like your exhaust manifold plate has a hole in it.  I had the same problem on my 1st I/O years ago. Carbon is getting into you exhaust from the engine and water is getting into your engine oil.

Thats never good

[FishingTheFL]

I see why you said it was expensive.... Around $600 for exhaust elbow and water jacket! Hope their not damaged and its just a leaky gasket... Boat is turning into a nightmare

If I was doing the work. I would do a compression test too. All that hot exhaust getting into the cooling system tends to destroy head gaskets. That would explain the water in the oil

[chinook35]

That's what boat stands for. Break. Out. Another. Thousand

[FishingTheFL]

Yep... Guess I gotta pressure check it to figure out exactly what I have to fix... Wish I knew more about damn motors... Back to googling... -.-

Fixmymercruiser.com has had the best prices on manifolds I've found. Good service too.

Good luck!

I got rid of an I/O and went to an outboard figuring that if the motor died then at least I still had a good boat and could go buy a new motor. and vice versa.  30 yrs later, they're both still going strong.  (Only problem now is that if one dies, it'll cost more than I paid for both way back then).
