That sounds seriously bad. I would be worried if the water was in there 10 minutes.
I know I am not making you feel any better. Could you remove the injectors and crank it to blow it out?

Well this is a crappy way to end the season. Short story is, I'm 99% positive that I managed to get water in the cylinders in my Yanmar 3GM30F, and now have a hydrolock. Thankfully, the engine was not running when it happened, but I *did* attempt to crank the motor with the starter a couple of times before I realized what had happened. So now, I'm worried about significant damage from two angles: 1) Bent rods/crank/pistons? I'm inclined to think that the starter motor doesn't have nearly as much torque as the engine operating under normal load, so I'm hoping that my attempts to crank didn't permanently do any damage such as this. Thoughts? 2) Time: Unfortunately I can't get back there with tools and equipment to attempt to rectify the hydrolock until Sunday, which means the engine will have been sitting there with water in the cylinders for almost 4 days. It's mostly fresh / brackish water (boat's on a mooring in a river mouth). Chances of corrosion in the cylinders requiring a teardown? Anyone have any experiences with hydrolocks they'd care to share? Ugh...
