One thing I always do when I start the engine is to make sure water is
spitting out the exhaust. If your exhaust outlet is under water, you
can't do that. Also, like any thruhull that's under water, you should
have a shutoff valve for it. But I don't think you can (or should)
put one on an exhaust outlet. So that leaves maybe moving it higher
up. Something you might have thought about when the boat was being
repaired but you can still do.

Hi, Steve,

We look at our filter for water movement. If it's coming in, it's
going out. More reliable than trying to stick our heads out to see
whether there was a splash, in any event, and much quicker as it's
right next to where the key is...

We thought about relocating the exhaust, but got talked out of it for
a variety of reasons. On our next extended haul we'll revisit doing
it out the transom rather than low on the stern side as it is now...

Wilbur, I don't know his system, but another's I know of uses a direct
drive 1HP motor to chill cold plates. Very high amps, relatively short
time. My estimated (see my upcoming electrical budget and scenaios)
use is over an entire day, but is more like 35-40AH.and uses, when
running full blast, as approximately yours does, 4.7A..

Skip, it could also be coming in and going into your bilge. Also, having the
exhaust under water makes it more likely for water to back up into your
exhaust system in following seas. Free and clear of the water is for sure
the better way to go.

Bob always walks back to see if exhaust is coming out, even if
everything sounds all right from the cockpit. I don't think much of
your method.

I agree - we have a high loop which goes up into the cockpit to keep
waves from coming into the engine through the exhaust, and an
anti-siphon break on the cooling system.

I don't know what our refrigeration system uses when it is hooked up
to dock power. When we are not hooked up, we run the engine driven
system for 45 minutes twice a day. The frig is not attached to the
batteries. We have 19 cu ft of frig - 1/3rd freezer. It will not
freeze ice cubes or keep ice cream, but it will keep meat frozen, and
is perfectly adequate for our needs. Actually it is rather too big
for us, but that's what came with the boat.
