Well, if the engine is 4 or more years old, it's probably a manifold or
riser issue. As far as finding water in the cylinder, I'd tear it down. What
I would do to it at that point would be determined by how much money was in
my pocket.

I've got a 4.3 GM V6 in my boat. I pulled out the spark plugs and water
came out of one cylinder plug hole. This is the first thing I've gone to
it
this year. Is my motor junk?
