Is a little Generator worth it?
I have a Tohatsu 9.8 outboard on my 30' 1974 Grampian sloop that I bought a few months ago. Very much enjoying the boat. My understanding is that the outboard charges the battery with 7 amps DC power.
I read the specs on Yamaha and Honda Generators. They put out a whopping 1000 Watts AC power! Well AC is something that I don't use much on my boat. DC is what I need. They only generate 7-8 amps DC power. 8amps x 12 volts = 96 watts DC.... I think that ain't much. I got three 90 (+-) amp batteries. Does that mean I got to run this generator for nearly 30 hours just to charge the batteries?
