Here are some pictures of yet another impromptu Willard Perkins
4 108 project!
We went on a sail to test the new electrical system
a few months back and on the return when we were getting turned around by swells and my bad ability to sail down wind
, I started the engine
in frustration and heard a bad sound. It did not sound like the engine
, but it was associated with the engine. After OTHER intervening repairs
, I finally got around to starting the engine again and once again there was that sound. It was a loud howling noise
that disappeared after a few minutes. It seemed to be coming from the water
After tears and ripped knuckles, we finally got the pump off. And there was a piece of a curved blade jammed in the housing. The good news is that the piece fit exactly one of the rubber blades, so I know no small pieces got into to engine. You can see the broken blade jammed in the housing. And you can see my frustration in the chewed screw heads
The rust comes from the heat exchanger's (above) aluminum
access plate which literally corroded enough to rain coolant
down on the impeller.
