Thanks again jgmo. the crank doesn't look scored at all. Maybe we will just put it back together and see what happens. 50wt oil maybe the way to go!
Could be getting too hot...hows the impeller
That can happen if junk gets in, or if oil cahages aren't done for a LONG time, or really crappy oil is in use. Glad you found it!
Was going to replace the impeller and distroied the motor. But I did save the power head. The drive shaft is still stuck. I've been keeping it oiled while
Excellent advice. I'll check that out as soon as I get a chance and report back my success, or lack there of
