Default Replace alternator in 5.7 Mercruiser?

To make sure the insurance company did not have a loophole, you could just
add brackets and a marinized alternator. Figure out the proper pulley size
to get a good generating output at the normal engine RPM's.

It is an automotive / truck alternator. With the only changes screening

all openings. Prevents flame propagation from nisde to outside the
alternator. Same for starters.

I agree, except: keep the known working one as a spare. [every once

in a
while, a "new" one fails pretty early.]

They can last as long as car alternators, if the engine compartment

is
fairly hospitable, since they usually ARE car alternators.

Marine alternators are intrinsically sealed. Anything less would

promote
ignition potential in the engine compartment. One would be ill

advised to
put an automotive alternator in an engine compartment, for an number

of
other reasons as well.

Oops! I intended to say "usually are essentially" car alternators. The
Hitachi on our Yanmar sure looks like the one in my old car. I'm sure
there are differences, but the base technology isn't going to be too
different.

So; in a non gasoline situation (Volvo MD1B diesel) would you
advise using a truck/car alternator? The existing engine has an a
12 volt 8 amp. Bosch starter-generator. It's difficult to keep
the battery charged with that. We would like the charging
capacity of say a 60 to 100 ampere alternator.
Any advice welcomed. Terry.
