Hello :

I have a 2003 Larson Cabrio 254 Cabin Crusier w/73 hours on the 5.7 Volvo Penta
I/O.

Have recently discovered water in the engine oil. The dealer's mechanic is
telling me this is "Normal" and may occur if the boat ingests water while coming
down off-plane too rapidly or even if water is splashed too high while putting
the boat in the water at a launch ramp.

Seems this is TOO easy an "explanation" for what I think is a defective engine
gasket.
IF this IS something common, I'm amazed more people have not complained to the
manufacturer's about designing their boats better to avoid water ingestion.

I've also heard water ingestion is a common problem on Volvo 8-cylinder I/O
engines. There is apparently a problem with valve timing being off - this allows
the intake stroke to pull vacuum while an exhaust valve is still open, thus
sucking water into the cylinders. Has anyone here heard of this or have further
details ?

Thanks in advance !

Ralph
