hydrolock on Kawasaki

First one I heard of hydrolocking........
Did you run the ski after you flipped it over?

I don't know about four strokes but two strokes must be rolled over in
the proper direction or water goes back into the engine. I imagine it is
somewhat similar with four strokes only it would come back in through
the valves. It doesn't take much to hydrolock a motor and four strokes
are going to be more sensitive because of all the moving parts. Now, I
would like to know how Kawasaki came to this determination versus a
defect in assembly. I don't believe there is a flaw since there are
quite a few four strokes out there that are running fine over long
periods of time but if you don't get the water out of a motor, it will
destroy itself over time - sometimes almost instantly, other times it
takes a few hours.

Kjell Martin - It's the water that got into the motor tthat counts, not the
water that is in the engine compartment. What should have been done
immediately after the "Turn-over insident" is to remove the spark plugs and
turn the motor over for 10 sec. intervals about 6 to 8 times to make sure to
remove the majority of any water from the engine. Then change the oil to
remove any possibility that there is enough water in the oil to reduce the
"Lubricity" of the oil. Having NOT gone thru this proceedure would make it
very unlikely that Kawasaki's diagnosis of the problem is incorrect and
especialy so when dealing with a 4-stroke. - Bob Dutton
