This came the site TomThorp referred to. A certain waxcase found it. We have investigated it further and it is a brand new engine designed for powered surfboards. Not a great volume though. As the applications increase so will OEC.
Excerpts from Machine Design, October 9, 2003. Page 48.
Over 400 of the powered surfboards called Igniter 2000s have been sold as production ramps up.
Inventor Robert Montgomery, lays over a turn at 45 mph on his Igniter 2000, a surfboard powered by a 45 hp, two cylinder opposed, two stroke engine.
The engine is the heart of the design. "We've measured up to 56 hp on the dynamometer," says Montgomery. Orbital Engine Corp. Ltd. (Australia) is supplying a fuel injection system. A prototype four stroke design is running and will weight only about 5 pounds more than the two stroke, which is remarkable. One of our competitors has a 50 hp outboard that weights 200 lb more than its two stroke version. Our four stroke will weigh under 50 lb and deliver 50 hp.
Two and four stroke versions share many parts. "When we get into the four stroke production on a second line, the left side of the crankcase will simply be exchanged for a chain drive to cams,' says Montgomery. The transmission and gears are the same on both engines.
The engine measures about 6.6 in high, 10 in wide, and 16 in long. The two stroke will run faster than the four stroke, 10,000 rpm vs 5,000 rpm. Montgomery expects to tune the engine for max power or most efficient operation to handle other applications.
Even Zodiac, a maker of inflatable boats, is developing a 9 foot dingy around Powerski's 45 hp engine.
