[C38] Changed seawater pump impeller fail

[Max soto]

Wow, honestly this is a though one..  years ago I had a persistent problem that there was no water in the exhaust, but it happened every now and then...  turned out it was a little piece of mud or barnacle that was trapped between the thruhull strainer and the barbed fitting on the other side of the valve.  That piece seemed to have life of its own. I blowed air through the hose and easily heard the bubbles coming out on the water, so I thought the intake was not the problem.  This piece was freely moving in the thruhull and clogged the intake every now and then. .. just my two cents.

I cleaned the cavity (there was some salt buildup, my fault for waiting too long)  and when I proceeded to put the new impeller (looks exactly like the old one), I was unable to put the snap ring back. I'm not sure how important this is. In any case, I put the cover on with the new o-ring and started the engine.
