Re: New 175 am alternator

This isn't advice, just our experience.  

Our boat was one of what seems to have been few SMs that were delivered with the "standard" 50 Amp alternator.  For the way we use our boat, that has been completely sufficient.  It supplies all the power we need when motoring, with enough left over to run the watermaker, or top off the batteries.  It's rare that we leave an anchorage with less than 80% charge in our batteries, so we are not normally asking the main engine alternator to deliver very much in the way of charge.  If we actually need to bulk charge the batteries while underway, we use the generator.
