It's a long story, but the exterrmrly short version is,,,, I had a 40 hp rude 2 stroke on a ski boat and flipped it upside down going wide open. No one was hurt, thankfully. Took about an hour to get it recovered and to the bank. Pulled the spark plugs out, turned the motor until all the water seemed to be out, put some oil in the cylinders and ran it some more till all that seemed to be out. Replace the plugs, cranked it up, went back to pulling some skis. Ran it several more years without incident.
