Took a trip to Northport this past weekend. We left on Sunday early. Turned the raw water valve on but in my haste and excitment to head home with great wind that morning i actualy was turning the valve off. It was already on. Blower on, engine start was fine. Except for my second mistake was not looking for water out the stern. idled for a minute or two then cast off the mooring. Went about 50 or 75 yards when my one sister yelled SMOKE! SMOKE! I imediatly gave her the tiller and climbed down into the cabin. Turned off the engine, pulled the fire extinguisher out and pulled off the panel to the engine. In retrospect maybe not the best thing to open the panel that soon. I thought if this was a fire i just gave it lots of air. As this was all going on I was smelling the familire sweet odor. I was praying please o Lord be an anifreeze leek. I saw no fire no smoke just lots of steam. Confident we were not on fire i quickly turned my attention to the fact we had no power and were drifting in a relitivly narow and busy channel. got the anchor deployed and started to calm myself. the plastic overflow tube was resting on the heat exchanger and melted spraying antifreez over a very hot engine.
So my question is what posable damage could I have done to the engine. My short list is raw water impeller, fresh water impeller, warped heat, burnt oil. Any thing else? O yes a badly bused ego. After cutting the damaged tube back and relocating it so it would reach i had to add strait water the the exchanger and restarted the engine and all seemed fine oil pressure, temp. and water out back. We made it home without a problem. Ran on engine for about an hour or more with no abnormal noise or temp. problems or oil problems. I plan on draining and replacing oil (Rotla 10/40) and same with antifreeze (50/50 mix). My concern is any long term damage that may have been done.
