Re: [California PortaBoters] Re: Confused about the real power of electric outboard
- Thanks Mike
I was drawn by the quietness of the electric engine. Now I'll try to get a "relatively" quiet gas engine . 4 to 6 HP seems to be the right recommended power.

I don't know who's "thumb" he's going by. Try this.
The Ray Electric Outboard Motor series or system 200 is rated at 2.5
hp max output. Runs on 36 volts. It uses 6 (recomended) 12 volt
batterys. Two banks of three. 2.5 max output drawing 65 amps and
makes 135 lbs. of thrust. The motor alone weighs 74 lbs and the
whole package weighs 530 lbs. It will push a small fishing boat (?)
along at about 6 mph.
Save yourself a lot of time and go out and find a small (gas)
