Ok, I just (finally) heard back from the service center. It was in fact
hydrolocked. All 6 cyls. had water in them. They did a compression test
to see the extent of the damage and said that one cyl was reading 210
and another 140. Now I understand that this kind of variance is way
off, but how can one cyl be reading 210 on a 10 yr old boat with
probably 500 hrs on it?? The others were in the range of 150-170. Are
they pulling my leg or is a reading of 210 even possible? Any insight
would be much appreciated. I'm thinking I might just go get it and run
it a few hours and recheck the compression.

I have read on a few other sites of people that have had the same
experience. Hydrolock at high rpm shutdown... I think I might just go
pick it up from the shop this weekend and give it a try. No harm since
they apparently are just going to have it sitting there for another few
days before they can even check it. Thanks guys, I'll let you know what
I find out.
