Sorry, Gould. Bad day. Still, my point is made. The idea is that heat
exchangers are to allow use of the system when the boat is not tied to
shore power.

Perhaps this prevelance is influenced by geography, but I've seen this
type of system on more sailboats than powerboats of comparable size.
These observations support my statement that this setup is more prevelant
in sailboats. Sailboats are more likely to be underway for longer
periods of time and are more likely to be anchoring without ammenities.
Add to that my statement was in response to a powerboater who has never
heard of such a system and it supports my viewpoint...

You point out the obvious that these can be used on powerboats as well.
Your personal observations may disagree with my statement that the system
is more prevelant among sailboats, but your just picking nits.

A lot of the tournament ski boats have heat exchanger showers. Would skew
the numbers away from sailboats.

In all honesty, I'll have to check if mine has an exchanger inlets when I
get up to the boat. It's a six gallon unit, and I didn't think it did.
I know my dad's 6 gallon system is not hooked in either. Whether his
tank has the capacity to run off the engine, I don't know.

Do alot of power boats in the 40' in under range in your area use the
engine? Many of the ones I've seen in the great lakes region did not.

In cases where such a heater is installed in a boat that doesn't have a closed
cooling system, I usually see the fittings for the coil capped off.

I have seen some household type water heaters stuffed into the bilges of
Cruise-a-homes and outboard powered boats with shorepower conections. The vast
majority of time they rot out very prematurely.

=====================================

The key is closed cooling systems. On the great lakes closed cooling
may be less common. In salt water areas, just the opposite.

While wally is right on both counts, I still wonder if a water heater
hooked into a raw water cooling system is more of an exception than a
rule. If the majority of powerboats have wally's setup, then perhaps my
experience with powerboat systems is more limited than I thought.

Either way, since Wally posted on the topic he is obliged to helpme fix
the problem based on the little known usenet 1000 meter proximity rule,
with beers at the Vikings Den to be rendered as payment :^)

Why is that the key? My 29 ft SeaRay had raw water cooling and was
hooked up to the water heater. Worked great.

The engines heat up to around 150-175 degrees no matter if you have raw
cooling or fresh cooling.

Note : Great Lakes comment since corrosion inside the water heater is
nil.

Hey Wally!

Sorry I missed your response. I went out late Friday afternoon and
Returned Saturday and Sunday to remove the outdrive and scrub out the
cabin.

As you come down the small hill the boat is on the immediate right, across
from the PWC docks. It is a white hull with a aqua-marine gel-cote
stripe. It is dry docked next to the fabled 42 foot Sea Ray that came in
last fall with half of the bottom town off. BTW - What is the story with
that boat. do you know?

If you see a car parked off to the right, stop by and say hi. The frige
is working, so I have cold beer and pop.

Hey Bob, I was out there today and probably will be tomorrow. I'm
finally getting the thing in shape.

Where is your boat and when will you be out there?

I carry a fair amount of tools with me.
