Hydrolocked after winter storage

Only way you can get that kind of corrosion in the cylinders is if the engine was not properly winterized - IE fogged. The fogging process coats the piston walls with oil to prevent aforementioned corrosion. Furthermore it sounds like the boat was stored in a place with a high amount of humidity or where condensation was forming which is not good either. Sometimes that can be a result of large temperature swings in a short period of time where cold metal tends to attract moisture similar to a cold glass a water on a hot day.

No matter how the moisture got in there, proper preparation of the engine prior to storage should have prevented that kind of damage from being done. I'd be having a serious discussion with whoever did the winterization that's for sure!
