A 4-stroke engine is more robust and can go up to 300-500 hours.Four-Stroke Engines: The vast majority of modern jet skis from leading brands like Yamaha, Sea-Doo, and Kawasaki are equipped with four-stroke engines. These are more durable and can last between 300 to 500 hours on average.A 4-stroke engine takes four piston movements—intake, compression, combustion, and exhaust—to complete the cycle. This leads to a more controlled and efficient process, resulting in smoother operation and longer engine life.
