Scary feeling indeed. A couple years ago I was running my Grady White to the marina for haulout when not far from my dock, the engine thermometers showed my engine temps were waay high almost overheating....I stopped opened the engine box too see raw cooling water pouring from the heat exchangers. I shut the enignes down and pumped water out....I later found the screws on the cupholder next to the helm. Turns out my father had opened the heat exchangers to let the raw water drain out because we were excpecting a really cold few days (this was late Dec....temps in the teens at night) Well after draining the heatexchangers of raw water he never relaced the plugs.! I replaced the plugs and was back in business.

Those first few seconds when you see that water where it doesn't belong are indeed scary.

Do you guys suggest totally closing up the foward drain hole on the 20 MA or should I just change the plastic fitting to a bronze?
