PSI's patented two-stroke, water-cooled engine built for the Jetboard puts out 45 H.P.. The dimensions of this revolutionary new engine design is 6.5 -inch tall by 10 -inch wide by 17 -inch long. This 330cc engine currently weighs over 40 pounds, but use of a metal matrix composite material will drop the weight to approximate. 38 lbs. The entire craft was engineered with Parametric Technology Corporation on HP Workstations.
An axial flow jet pump delivers over 350 lbs. of thrust through
a proprietary gear-reduction transmission. The gear reduction, built into
the bottom end of the engine, is new to the power watercraft industry. It
enables engineers to match the engine's optimum rpm to that of the jet pump
to enhance the craft's performance.
The PowerSki Jetboard's design puts the center of gravity under the rider's feet, rather than behind or in front of the ride-as is the case with similar sports water craft. Dual hydrosteps on the bottom of the hull put the pivot point directly under the rider's feet, enabling high-speed planing and turning. The hydrosteps lift the craft partly out of the water as it skims along, and direct the line of water rushing past the rails during top speed turns, stabilizing the craft.
The modular handle assembly consists of the grip, start/stop buttons, independent
left and right thumb throttles, speedometer, fuel gauges, and safety kill
switch. Sub-assemblies are attached to a four-foot long arm-pole consisting
of steel cable and a sleeved wire harness covered by injection molded rubber
that provides structural strength.
The grip is removable and replaceable. Scientifically engineered finger grooves to prevent hand and wrist fatigue are coated in cushy soft, textured sanitex/ saniprene rubber and nylon laid over a thermoplastic elastomer surface.
There were five significant natural forces the engineering
team had to deal with; weight, buoyancy, hydrodynamic lift, drag, and thrust.
The Igniter 2000 combines a high thrust to weight ratio with a hull/rail
design and center of gravity placement that stabilizes the craft at all
speeds. The design also enables high-speed planing and high thrust "G-Force"
turns with simple shifts in weight of a rear-mount.
