Seattle, WA December 13, 2018 Located on the shore of Lake Union, Pure Watercraft set out to redefine boating with their Pure Outboard electric motor. In the process, they developed a battery pack with the highest energy density in marine, matching that of the best electric cars.
The 118 lb battery pack uses industry-leading Panasonic lithium-ion cells and has a capacity of 8.85 kWh. More energy per pound means a boat can get up on plane more easily and stay on plane for longer. Active thermal management leads to longer battery life and the ability to travel greater distances at high speed.
It’s also clean. The Pure Outboard emits no exhaust or noxious fumes, spills no oil or gas into the water, and is whisper quiet. It starts at the touch of a button, is immediately ready to drive, and charges easily via a standard 120V or 240V outlet available in most garages and marinas. Between the savings in fuel costs and the elimination of maintenance costs, a typical outing will cost about one or two dollars in electricity.
“Our team built the outboard motor and battery pack system from the ground up”, says Andy Rebele, founder and CEO of Pure Watercraft. “Throughout the process, each component has been designed to maximize efficiency.”
The current system is set to replace traditional combustion outboards up to 40 horsepower. Range depends on use: a typical aluminum fishing boat equipped with two battery packs could go at a trolling speed of 3 MPH for about 50 hours, or 25 MPH for about an hour. Charge time is as fast as 90 minutes from half to full charge using a 240V outlet.
The quiet speed of the outboard has already caught the attention of anglers seeking a competitive edge. Likewise, elite rowing teams such as Harvard, Yale, Stanford and the University of Washington have pre-ordered the Pure Outboard for their coaches. “We’re eagerly awaiting the Pure Watercraft system because it will transform how we coach our team,” says Michael Callahan, Head Coach of men’s rowing at University of Washington.
Pure Watercraft is starting customer deliveries in January 2019 and is currently accepting $500 pre-order deposits. A system starts at $14,500 for a Pure Outboard motor and one battery pack.
