The marine market encompasses a wide variety of vessel types, applications, modes of propulsion and regions of operation. For decades two-stroke engines have been the standard motors used and they have become one of the major polluters of our inland waterways. According to one study, a 70-horsepower two-stroke outboard motor emits the same mass of hydrocarbon pollution in an hour as a new car does after driving 8,000 kilometres.

As a result North American and European legislation concerning marine engine emissions is under constant review and more challenging emission standards are expected to become law in the near future.

PRINS has developed several key components that could be used for LPG and CNG applications on a wide range of two-and four-stroke marine engines.
