Also, if it's not CG approved, and you have a fire because of it,
your insurance company is going to walk away, it's your problem. I'd
stick with the normal marine alternator if I was you.



I think THAT is a very important point, too....

Doesn't the CG requirement kick in only
for gasoline engines? I doubt the
insurance company could walk if the
engine is diesel.

The CG requirement is for diesel as well, diesel fuel burns quite well.
Cracked high pressure diesel fuel lines can produce a very fine fuel
mist, and it makes for one hell of a fire if it hits a spark or a hot
dry turbo. Give an insurance company an excuse to walk away from paying
on a loss and watch how fast they run. That's what they pay their
people to do. I looked quickly at my Cat alternator part numbers, they
look like differant part numbers than the truck numbers in the catalog.
It just isn't worth it.

The surveyor that my insurance company hired to monitor my progress has seen
the Leese Neville which is not "USCG approved" and accepted it with out
reservation.

Actually neither 46 CFR 176 or 46 CFR 183 require approval of alternators in
diesel powered environments. The only source I can find that recommends
using only marine approved alternators is our friend David Pasco and he even
has the reference to the requirements wrong. J1527 is specific to hose
standards, not alternators.

Capt. John, I'd really like to see a
cite for the specific USCG regulation
that requires ignition-protected
alternators on diesel engines. 33 CFR
183.410 addresses only gasoline, and
even then gives a pass if the gasoline
is on the other side of a bulkhead, etc.

Here is the applicability paragraph
(183.401) for ignition protection:

(a) This subpart applies to all boats
that have gasoline engines, except
outboard engines, for electrical
generation, mechanical power, or propulsion.


FWIW, I'm not advocating anything and am
making no judgment here on what is and
isn't worth it. I'm simply seeking
clarification on what the regs actually
say.

Chuck
