[Public-list] NEED MORE HELP ON MY COOLING PROBLEM

[Joe]

John: I had the same problem when I first got my Alberg 30. It has an
Atomic 4. I replaced the impeller, fixed the pinched hoses and tried to
clean out some of the debries blocking the passages. Each time I used a
magnet and coat hanger, and each time I thought I had it licked only to
have the overheating problem return again and again. I even flushed the
engine with a lite acid. But after months and months and repeated
tries--still it overheated. My symptoms were just like yours, ran well
for a few minutes then overheated.

Then one day I hooked a hose up to the raw water intake line and
essentially "blew" debries out the exhaust fitting--only to have it
overheat again. I reversed the hook up, connecting the hose to the
exhaust fitting at the engine manifold, and look out! (leave the
thermostat housing off.

I blew out about one 16oz cup full of rust flakes and metal debris, all
over the cabin. They had been trapped somewhere in the manifold in a
unreachable space. In some cases it came out as a paste. The point being
you have to reverse the waterflow maybe to get the passages clean. After
that, no more overheating.

Not too much water pressure, mind you. Just enough to get things moving.

Good luck

So, after a few days of good, cool running with my new impellor, I have
a new engine cooling problem.  The problem is that once the engine heats
up, the flow of water stops.  When I first fire up the engine the flow
of water out of the exhaust is like a hose, then it drops to a trickle
and finally shuts of completely.  This process takes about 5 - 10
minutes.  I am guessing that it is a thermostat problem.  Any thoughts
or experiences from the group?
