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...
