[Public-List] A4 overheating

[Meinhold, Michael J.]

Gord - 

  The passages are moderately wide and a good strong pump should do a
good job clearing itself.
  If they hooked it up and got good water out the exhaust initially,
then I would suspect a blocked inlet.

  Close the through-hull valve, remove the hose from the pump and
elevate the end above the waterline, open the valve and lower the end.
If it doesn't gush impressively, then try blowing back out or clearing
it mechanically.

Subject: [Public-List] A4 overheating

Hi gang

Surprise is on day four of a very nice cruise in company with friends
who sail a Columbia 29.   Their A4 is overheating and we are towing them
a lot.   It has a new water pump that throws lots of water, and the
thermostat was already removed... Not much water is coming out their
exhaust compared to ours

I noticed in the thermostat housing there's lots of rust flakes.  We
removed them but guess lots more is blocking the cooling jackets.  

Is there a way to reverse the water flow in hopes of moving the rust
flakes?
