THE FOUR-STROKE ROTAX 4-TEC ENGINE PLATFORM

Our Rotax 4-TEC engine platform continues to leave every other watercraft and sport boat behind. Whether you're a serious rider or just getting your feet wet, there's a version with the power and performance to please. Equipped with electronic fuel-injection,he Rotax 4-TEC is world-renowned for packing an amazing amount of power for its size and weight. (We practically invented the high output engine.) Also standard on all 4-TEC engines is the industry's first closed-loop cooling system. this innovative alternative to traditional open-loop systems uses the watercraft's aluminum ride plate as a heat exchanger (like a car's radiator) to keep the engine and it's coolant at the ideal operating water temperature. So. To supercharge or not to supercharge. That is the question.
