Elco Motor yachts has been in the business of electric propulsion for boats since 1892. Yes 1892! You may not have heard of them, because, until recently, they specialized in inboard electric propulsion for larger boats. see their history here: http://www.elcomotoryachts.com/history-of-elco.shtml
Within the past year Elco has gotten into our end of the industry. They have recently released 3 electric outboards. These are 5, 7 and 9.9 HP. There is a 15 HP outboard on the horizon. These are brushless, water cooled outboards. Elco is scheduled to release Lithium power systems within a few months. If these new outboards, and the new Lithium power supplies perform as expected, the next year or so will provide electric boaters with an interesting set of options. I have arranged with the sales manager of this product line to visit Baltimore with one of his motors and Lithium batteries to provide a demonstration to our club. I'll keep you all informed when we have a schedule. The photo below is the 9.9 pushing an 18 ft Sea Ark (reportedly at up to 9.3 mph). We are in the process of finalizing a club discount.
I thought you would all be interested in new options for our reservoir rigs.
