When was the impeler last changed in the lower unit? It's a good place to
start.

Hi all,

Trying to diagnose my 1993 OMC Cobra 4.3L water flow troubles. The
motor starts and runs well, but no water flows thru the engine. I
removed the thermostat to rule out whether this could be the trouble.
Even with the thermostat out, there still is no water flow. Short of
taking out the water pump next, is there anything else I can try before
I target the water pump?


thx in advance,
