If you have a good shorepower
Charger, it’s going to be much better than any
alternator, in my opinion.
First it can be BIG, and if it’s a good one much smarter than an alternator external
regulator.
Use the generator as long as you have a good shorepower Charger, if you don’t, then get one if possible.
In my opinion it’s more efficient and cheaper in the long run to use the generator to make electricity than a
propulsion engine.
But then I wouldn’t likely try to use my generator to drive the
boat either
