Powerski Jetboard prototype


The Powerski Jetboard prototype featured in Gizmo magazine during 2002 is finally ready to go into mass production. The Jetboard is a combination surfboard/JetSki incorporating a 25 x 43 x 16 cm high, two-stroke, water-cooled, 45hp engine and an axial flow jet pump into a (slightly larger than average) surfboard form-factor to deliver a stand-up ride over flat water at speeds up to 65kmh.


Using sophisticated CAD software and new composite production techniques, the original Jetboards featured in Gizmo have been substantially reduced in weight, improved in drag co-efficient and have improved air intakes and safety features.


A sophisticated hand operated throttle includes a start/stop buttons, independent left and right thumb throttles, safety kill switch, plus speedometer and fuel gauges are found on a modular handle unit connected to the board via a 1.2m arm-pole made of rubber coated steel cable.



The patented single cylinder, two stroke 330cc engine - the SuperTorqueXT - runs at 45 hp enabling the jet pump to put out 350psi of thrust. The current version weighs around 18kg but this is expected to be shaved back as the design evolves. The drive train includes gear-reduction transmission built into the bottom end of the engine that optimises the transfer of engine rpm into the jet pump. Development of an electric Jetboard is now well underway. An announcement in December 2003 flagged the formation of a joint venture between Powerski International and Global Electric to create a Powerski Jetboard’ powered with by a Lithium-ion electric motor.
