The water pump impeller replacement was successfully accomplished. But I have an issue that concerns me. There were 3 fins completely broke off inside, and the pieces I pulled out didn’t account for all three fins. I checked and cleaned out the lower intake area and found another piece, and removed the upper water intake tube and base hooked to the upper part of the outdrive, and everything was clear.
my question is this: where could these broken pieces have gone to? Could they be sucked into my engine water jackets and clog something up? How can I check this out?
the motor was ran at 3000 rpms underway for 10- 15 minutes after it first overheated. The remaining 3 fins of the impeller pumped enough water to keep the engine at normal operating temp at higher rpms. Kirk
here is a photo of the damaged impeller.
