I have several boats, Lloyd, and, unlike your collection, mine has no
junkers.

But.. but... a gas INBOARD, Harry? Not an outboard? Say it ain't so, Harry
- say it ain't so!

Had some fun on my "junker" last weekend: 20-25kn SE, 4-6ft seas, crossed
Georgia St averaging over 7 knots (and burned ZERO dinosaurs!) Oh, and
when I did start the engine, it ran. Fine. No charging problems, unlike
yours...

BTW: The laughter was aimed at you Krause. *Several* boats? Perhaps
your modest 24 foot Parker , a canoe and a rowboat.....eh? I think Lloyd
owns more boats than that.

Hee-hee.

I'm no outboard guru, but that is a pretty stupid application of
engineering if that is the way the thing works.

Since this thing is a *regulator* is should regulate the current in
the stator and thus regulate the amount of current generated..... not
drop the voltage of an unregulated power source. Bear in mind that
this is a 200hp (+-) modern engine not a 1962 10 hp model that was
never designed with electronics, etc. in mind....

IMHO, this is probably more about using undersized solid state
components that must be cooled to (1) maintain predictable design ohms
and/or (2) keep from bursting into flame....


Maybe, but since it's called a voltage regulator I suspect it regulates
voltage, not current. True, it does regulate current to the battery by
limiting the applied voltage, thus less current flow. The excess voltage
developed by the alternator has to be dropped and the power or wattage
resulting generates heat. If it didn't get hot it would not be water cooled.

Wouldn't it make more sense to cut the source out of the system and let it
idle until it's needed? It would mean that you would have the battery in
the system acting as a supply and a buffer, but it would allow for free
wheeliing the alternator gearing with a solenoid like you do with a truck
air compressor or a AC compressor.

If I'm understanding all this correctly, some do:

Gene, I suspect your understanding of how it works is far more accurate than

Here's a real nutshell explaination.

Well, on an outboard, the Stator (winding) is made under the flywheel
instead of being configured into abelt driven package. Instead of a
field rotor, (automotive) the Yamaha has magnets mounted inside the
flywheel to draw a field. the automotive alternator, is actually a
3-phase DC generator (for lack of better terms) while the outboard is 2
phase.

they both do the same thing, jsut way different ways of doing it.

Yes, the telltale that tells you whether the engine is being cooled
properly by raw water was clogged.


The voltage regulator in the engine is WATER COOLER and draws its
cooling water through the telltale plumbing.


So the voltage regulator was NOT BEING COOLED properly and it reacted
by
giving me those voltage variant readings.


After I stopped laughing, the service manager said, "No, I'm not
kidding."


Well, I have no reason to think he's lying...but it is among the

Funny you should mention that. I know a mechanic who had a problem
with a Honda 225 - couldn't find it. The documentation was sparse and
the "factory" rep was really a salesman.

He finally went down the street to a Honda dealership and "borrowed" a
Honda engine guy - had it fixed in no time. :)
That's pretty cool.

I have heard that story from two other marina mechanics - apparently
Honda takes the approach that "our engines never break, so why should
we spend money on factory schools or service reps?"

I've also heard, second hand so it's suspect but the source is
reliable, that parts are a problem with Hondas for the same reason.



Well, the boat dealer's assistant service manager called, and...

this is hard to believe, but...


The reason the voltmeter was giving flakey readings was because the
cooling telltale (aka "the ****er") exiting the motor was "clogged."

Say what?

things I've heard this week.


Maybe he was trying to save you a dollar. Nobody would have guessed that as
the answer.

I still say WNL.

However, that kind of heat suggests the surplus energy from the
generator is being dumped rather than the generator itself being
regulated. I don't know, but that does seem to be a bit dated.
