I left the engine cooling water intake seacock closed and melted my impeller and overheated my engine. Yanmar 2GM, very low hours. Happened with the marina. Ran for maybe 7-10 minutes warmup at the slip and 7 minutes from slip before noticing the problem. Smelled exhaust from the cockpit and heard whistling and whining noises out exhaust pipe before the noises it suddenly settled back to normal but still with low amount of smoke coming from the engine. The impeller is disintegrated into little 2-3mm chunks in the pump.
After I replace the impeller, what other procedures should I do? I imagine all the little impeller chunks made it into the engine and exhaust? Any tips on what to do to avoid engine problems next time I'm rounding the Cape?
Cheers.
