Thread: water in oil

Only takes a very small amount of water to contaminate oil. It could just be a small amount getting in. It takes an awe full lot to hydro lock. I’ve only hydro locked with fuel and the fuel in the cylinders definitely contaminated the oil. I hope for the OP that the new manifilolds fixes the problem.

If I was the OP, I would be asking
Why did 2 exhaust manifolds crack?
Was the oil checked previous to this event to determine if there was water intrusion?
If there was water intrusion was the oil level above the high level mark on the dipstick?
Was it a ballast hose or a cooling hose that came off and why? Was a clamp loose?
Did the engine overheat?......did a warning come up on the dash?
Did the boat run fine after the ballast hose water was removed, and the OP thought he should check his oil and that’s when he discovered it milky?
Seems odd that everything was fine all season then all of a sudden he needs 2 exhaust manifolds from a ballast hose coming off.09 21v LAUNCH

FINAL UPDATE
Moomba dealer replaced both exhaust manifolds,oil,filter spark plugs and water pump impeller.
Before repair cylinders compression tested at 210-220.
Launched boat in lake and ran for forty five minutes. Appears to be normal.
For those members that questioned if cracked manifold can cause water in oil I would suggest asking the question on google and see the many affirmative answers.
