1998 GTX Limited water in engine cylinders

I'm working on a 98 GTX Limited for a friend and came across engine cylinders that were full of water, rear was full, front had some in it I just read this from a sticky thread under the SeaDoo forum here. "Since late 1997 is the first year for the 947 engine, on the first models they do have some problems with water ingestion as well as some pump issues"

I'm not sure how long water has been in the engine cylinders but the ski has been sitting on a trailer uncovered for a year. I would have figured an engine sitting for a year with water in the cylinders would likely be froze up tight but this engine does turn over relatively freely after removing the plugs and blowing the water out. I sprayed some WD-40 in the cylinders, blew that back out, put the plugs back in and spun it over which it turned over freely with sounds of building compression.

Where should I start with this issue? I was thinking checking the fuel tank and carbs for water but that sure doesn't look very easy to access with that large expansion chamber exhaust system over top of everything.

Engine needs to come out and be torn down. Rust in the cyls is not as crucial as rust in the crank and rod bearings.

What's the typical entry point of the water? Does it typically come in through the intake, exhaust or internal through head gasket passages?

It all depends on what happened. It could be from running on the hose, and not turning the hose off first, but sounds like it was either submerged or left with the seat and air cleaner off.
