Re: [OMC-Boats] Cooling issue

Would be nice if we had some archives we could refer to but at the risk of repeating a suggestion, you might consider installing clear hoses that feed from the internediate housing to the rear of the exhaust manifolds.  As long as those stay full of water, you should be good to go!  If they don't, you know you have an impeller problem.

Let me bounce this issue off the wise old list.

So I finally figured out which hole in the outdrive is the "pisser"
hole. It's directly under the plate that covers the outdrive pivot on
the drivers side of the boat. Here's my issue. I have no water coming
out of it. As in none. I do have a slight dribble coming out from the
cover above the hole. Just a real slow drip. Easy fix. But, the lack
of water through the tell tale hole bothers me. Can it just be
clogged? I ran the boat on the hose for about 5 minutes, maybe a
little more. No water. Didn't seem to be over heating. I can get the
IR thermometer out and take some readings to be sure.

My question is this, I wanted to take this thing to the river tomorrow
for a test run. Before I go, I want to make sure I have water flowing
where I should. Is there a way to double check the "tell tale" hole?
Someplace else I can look for flow? Maybe pull a hose?With my IR
thermometer, where should I take readings and what should they be?

I can tell you this, there is 2 cooling hoses going to each side of
the engine. On each side, one was hot, the other was cooler. Is this
significant?

I'm know if I don't have flow that impeller is already garbage just
from the running I've done to tune it up. Which went well. it's purrs
and idles smooth as can be. But, if water wasn't flowing, wouldn't I
have noticed it over heating by now?

Any input would help me avert a meltdown. As always, thank you all!
