Normally after water ingestion one does an oil change, run for maybe
5 or 10 minutes then do another oil change before running the engine
under serious load and RPM. Then I would change it again. I can forsee\NO
situation where water in the oil is an accepted situation. I'd find a new
mechanic!

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

Water in Base Oil s ALWAYS a problem that needs correcting ASAP. You
should do an oil change and replace the oil filter before you run the
engine any more. If it was me, I would then put about 10 hours of
a Good hard run on the engine and do another oil change. Are you in
Salt water, or do you run a Heat Exchanger? I suspect that it is a wet
exhaust with no heat exchanger. If this is salt water, you got a
serious problem. If it is fresh water, it is bad, but not as serious as
if it were salt water. Either way, don't let that contaminated oil sit
in the engine.
