I had smoke coming out of the engine compartment due to overheating on Friday evening. Sailed back to the slip and ran the engine only long enough to dock the boat.
On Saturday morning my order was: 1) check to see if exhaust is spitting normally; 2) it was, so there was no need to mess around with the water intake, the raw water strainer, or the impeller – it wouldn’t be spitting normally if a plastic bag or something had been sucked in; 3) next up was the heat exchanger; 4) I don’t have a level gauge, so I started by looking for signs of antifreeze leaking – found some evidence (thank goodness it wasn’t internal to the engine) and a possible source (hose clamps needed to be tightened); and 5) added antifreeze to the heat exchanger system. In my case, it took nearly three quarts, so this was the problem. If the level gets low enough, the pump will not pick up antifreeze, and the heat exchanger system stops working. Once antifreeze was added, I ran the engine for half an hour and could not get the temp above 150. Had this not been the issue, next would have been the thermostat, then the mechanic.

What I thought. I’ll start with impeller and work forward(aft I guess). Jon Sent from my iPhone
