Does anyone know of a manufacturer that makes high grade raw water pump impellers? Something that will not break up in pieces after one season. The OEM brands have gotten worse over the years and the outboard pumps on many installations are barely visible. Years ago impellers wore out or took a set and caused an overheat. Now they crack or break apart and plug the heat exchangers downstream. I can read about changing them but to actually do the job I need a strong midget contortionist. I'm thinking maybe a polyurethane type impeller. Comments please. Capt. George
