I made mistake of running engine with Sea Intake Valve closed for around 20 minutes. Impeller pump disintegrated but no other visual damage caused. Engine still runs smoothly but hot. I have replaced Impeller rubber component, cleaned intake hoses and Sea Strainer leading to the Impeller pump. Some rubber debris from Impeller evident in the intake hose, but not in the Sea Strainer device. Have primed the impeller with fresh water through the intake hose.
This has not resolved the problem. Engine still not sucking sea water through exhaust pipe. Facing on Impeller housing is hot when test running engine, which makes me think Impeller is turning??? It does not appear that the Impeller is sucking in sea water from below as the Sea Strainer water level not changed and intake hoses do not seem to be bringing water into boat. Checked the inake valve, and it seems ok bringing in a steady flow of water from hull.
I am out of ideas. Please contact me ASAP if anyone has any ideas which I have not thought of.
