Personal Watercraft (PWC) have traditionally used carburated two-stroke engines. Recently the emissions produced by these vehicles have gotten a lot of attention from the Water and Air Quality Board. In California recent legislation will require PWC to reduce their emissions output by over 90% over the next several years.
The Rotapower engine, with two-stroke power-to-weight and cost, coupled with four-stroke emissions performance is an ideal power plant for the marine market in search of a light, clean alternative.
The Rotapower produces dramatically less unburned hydrocarbons than a traditional PWC engine. For more information, see the Emissions Performance page.
