Outboard Motor

The Wokart  (Photo: Wokart)

The Wokart is a featherweight asymmetric catamaran with a centrally-located 70 hp outboard motor that's designed to have the driving characteristics and power-to-weight of a go-kart. The automotive seating and controls make it just like driving a car ... and in four years of development and testing, no-one has flipped one over. Production begins next month and at €20,000 it offers all the fun of a PWC with a fraction of the environmental footprint. Unlike most toys, a horsepower upgrade is as simple as bolting in an 85hp motor, which makes it "unsuitable for the general public," a nice way of saying, "you can't handle this."  Read More

The 30 hp Aquawatt - the world's most powerful electric outboard motor

Champions of clean emission boating will be thrilled to know that rapid progress is being made in the field and much larger boats can now be powered by electric motors than ever before. Australian electric outboard motor specialist All4Solar has announced a 30 hp version of its Aquawatt electric motor which will become the most powerful electric outboard motor in the world. Due for launch at next month’s Sanctuary Cove Boat Show on Australia’s Gold Coast, the 30 hp (22 kw) Aquawatt is claimed to be three times more powerful than any other manufacturer’s electric outboard.  Read More

Advanced Digital Control for Yamaha Outboard

July 22, 2008 The concepts of drive-by-wire, steer-by-wire and brake-by-wire were initially eyed with much suspicion by automotive aficionados – how could a computer possibly hope to do a better job than a human being? Well, computers can do a much better job of these tasks, and will eventually be able to turn every aspect of our mere mortal fumbling into Lewis Hamilton-like driving capabilities. Now drive-by-whatever is invading the marine industry with Yamaha’s new second generation 250hp F250B outboard motor.  Read More

The 700 bhp water taxi

June 18, 2008 Outboard motors have seen enormous progress in a short time, not just in power output, but also in the sophistication of their emission-reduction technologies. We found a prime example this week in Sydney Harbour, Australia, where H2O taxis services 200 local pick-up points. The company upgraded its flagship 10.8m WaterBus from 450 bhp to 700 bhp using twin 5.3 litre V8 F350 Yamaha motors. Not only did it significantly increase cruising speeds, it halved the fuel consumption.  Read More
