The JetPac by Outboard Propulsion Systems
, LLC, has been successfully introduced after five years of research and marine testing. The new, patented, outboard propulsion system mates a reliable automotive engine with a high performance, large diameter, waterjet in a single, stand-alone unit. The JetPac mounts conveniently to the transom of most small craft. The self-buoyant power units are currently available with either a 150 hp turbo-diesel or 275 hp V8 gasoline engine mated to its 250-mm (10-in.) water jet. The patented design places all components of the propulsion system, other than gauges, controls and fuel, behind the boat's transom.
An automotive type cooling system, using a stainless steel heat exchanger in place of the radiator, is designed to ensure that the JetPac's internal engine parts are exposed to only fresh water. A special, clear, marine paint is utilized on the external engine parts
to protect them from exposure to seawater. Additionally, the JetPac water jet unit
is fabricated from marine-grade stainless steel, and features a sealed bearing system with biodegradable grease, all mounted into a fiberglass shell that is sealed and protected from the elements.
Said inventor, longtime marine engine designer and founder of Outboard Propulsion Systems, LLC, Bill Lawson , JetPac improves stability on many boats because it actually floats part — or all — of its own weight, replacing the dead weight of an outboard, inboard/outboard, or inboard engine. And since it mounts on the transom, our JetPac provides additional free space.
