Re: [OMC-Boats] Cooling issue

Ok, so on tomorrows agenda, pick up a tub. Let me ask you this, if I'm
getting flow on at least one side, that would mean that my impeller is
working to some extent, right? No way a bad impeller could only flow
to one side, really. I could see weak flow to both sides but not good
flow to one side and no flow to the other. The previous owner did say
that once a few years ago it started running hot, and he took the
manifolds off and found they were clogged with acorns or something.
But he said that hasn't happened since. I guess I better plan to get
up early tomorrow so I have time to do all this and still have a shot
at getting it in the water.
