Talked to a fellow at the boatyard from Washington State who said that he uses an 6hp electric outboard motor for his 26 ft sailboat. He says that the motor puts out the same power as a 9 hp gas outboard.Can be fully charged from 110 shorepower in a few hours with a run time of about 10 hours at hullspeed with no power drop off. Drawback is the weight of the 10 deep cycle 6 volt batteries. With the 50 lb. electric outboard motor unit thats a total weight of about 400 +lbs I should think. He noticed me changing the oil in my Nissan outboard said that gas powered outboards would be a thing of the past someday. Price of his electric outboard (60 volt)was over $4,000 plus batteries and charger.
