Does anyone have experience with V/P I/O Marine engines?

I have a newly rebuilt '84 Volvo Penta I/O marine 350 in my 84
Bayliner. About 10 hrs on it since the rebuild. I think / hope that it
was winterized correctly- oil change, ran anti-freeze through the
system, etc. . When commissioning the boat a week ago, we checked the
oil before starting it. It looked OK. After running the engine for
about 3 minutes, we checked the oil again and it looked like a vanilla
milk shake (water in oil!). I pumped it out, fogged it, pumped that
out, put in 5 qts of new oil, put the ears on, ran it again.... Same
problem. No freeze plugs popped.

Do you think the block is cracked? If not, can anyone tell me what
potential areas I should look at to find the contamination point
(water leak to block / oil)?

I only spent $3K for the boat and now have about $9K into it. It's
getting frustrating.

Well, you are stuck now.

There is water in the oil and it could be anything from a head gasket
to a cracked block.

Did it misfire at all? Sound like one cylinder isn't firing? Any
other symptoms?

agreed, and one step further. possibly a bad head.

When engine was rebuilt, did the mechanics check the heads for cracks
by magnaflux treatment?

Regardless, not a good sign.

I may be wrong, but It doesn't sound like a block to me, but more in
the head[s] and/or head gaskets.

trade in time... a marina could fix it pretty cheaply with young labor. of
course the end users are charged 50-80/ hour. personally i would try & trade
it in ASAP.

First step, pull the plugs and examine them to see which cylinder(s) is
leaking.
The next step, assuming that you find a suspicious cylinder, is to pull that
head, examine for cracks, and check/change the gasket. A new water leak may
be almost invisible on the gasket, so look closely, especially around the
problem cylinders, and hopefully you'll be able to check both sides of it.
Someone else will have to give you furthur diagnostic advice pending your
results.

Good advice. If you are really in love with the boat you might
consider repowering with a new long block but the boat is not really
worth that kind of investment.
