Hi,

My specific issue is this. New season - change the oil and filter.
I take the boat and run it on the lake for about an hour.
Come home, check oil level, and wollah - The oil is 3/4 the
way up the dipstick, yellow and as thick as mud.
Change the emusified oil and filter. Put new clean stuff in, take
the boat back to the lake the following day, and the same thing repeats.
The engine starts spitting the gunk out of the PVC tube and from
here, things get nasty. I understand condensation, but when I put
6 quarts of oil in and get 2.5 gallons out, there is something wrong.
It is not that humid here in central Texas. lol

Sometimes I wished I still lived in Colerado Springs. sigh

I have a mercruiser 4 cylinder that gets water in the oil ever season. The
boat is tarped and the engine cover is on and all entrances to the oil are
blocked. My understanding is that as condensation gets in and around that
area it can collect that way. Now mind you I live in Colorado so even
thought the boat is covered some water will drip through the tarp and wind
up in the bilge. With the cold tempters in the winter Ice will collect
around where the drain hole is and block the drain hole. So as it melts
and
freezes there is allot of moisture in the air around the engine. I found
that I just had to drain the oil and replace it . Then put some
penetrating
oil down the spark plug holes and let it sit for a few hours. Then it
fired
right up. I ran it and let it get good and warm. Shut it off and flushed
out
the oil again. It seems to be a spring ritual here with this boat.

Yes it does bill. But it is placed in such a manner that the water would
have to travel up hill in order to get to it. Plus a cover is over it
like
an umbrella. Unless the rainfall fills up the engine compartment first.
There is no feasable way the water could enter through it. I believe a
manifold is to blame or I have a cracked block. I'll keep you posted.

Thanks again.

It still has an intake manifold for the air doesn't it?

You say that the boat is stored outside..... I have seen a lot of
boats
that
have water in the oil. Sometimes it is caused by rain water
leaking
into
the
motor box and running down the carb. Check this possibility
before
you
go
any further....
