Definitely plan on using a marine grade alternator. The API Alternator I am looking for is better sealed and intended for marine applications.

To date have not had heavily sulfating, probably due to two facts: 1.) The boat spends 99% of it's time in the slip with the shore power plugged in. However, when I start taking week long voyages the risk clearly applies. 2.) I already have a Truecharge microprocessor controlled multi-stage battery charger wired into the the boat's shore power breaker box.

I will look into the smart charger external regulator.

Thanks....Steve H.

Cam--Is there some other form of battery charger you were referring to?
