After recently pulling the head on my 1960 10hp Sportwin to install a thread-insert into a stripped spark plug hole, I decided to replace the impeller. The water didn't seem to be flowing out of the motor in as much volume as I was used to.
I purchased the proper impeller kit and consulted the manual to install it. After getting it all back together and cranking the motor, I got no water flow out of the motor, and turned it off. Repeated attempts yielded the same result. I'm sure that the water tube is connected to the water pump housing, and I'm sure the impeller is sitting on the key pin and spinning.
The original water pump worked after I pulled the head, so I don't think i clogged any of the water passages in that process. I'd like to narrow down the possibilities before I drain the lower unit and fight to remove it again. What could be wrong?
