Also check the inside of the engine. I began having overheating
problems a couple of years ago (just once in a while). Chased
everything through the system and could not find a problem. Finally
(after having done it before) I took off the square headed 'bolt'
which holds the forward zinc - doubting myself because I had changed
the zinc earlier this year. And pushed a rod down through the input
hose - out came a very old rust stained piece of an impeller.
Apparently it only created blockage once in a while!!!! I cannot
recall having an impeller damaged in any way in the 19 years I've been
changing them, so it may have been in there forever.
Suddenly, the engine is running cooler.

Gary,
When I tried the pump on the boat, the outlet hose to the engine was not
attached. It's definitely a problem of getting the pump to self prime.
