You didn't say if you bought it new or used. Regardless, this boat is averaging less than 30 hours per year. As with all things mechanical, maintenance is the key to longevity. Regular oil and filter changes along with clean fuel will keep your engine purring like new. A big advantage jet propulsion offers is fewer moving parts. Again, this can add to the lifespan of your boat. I still see watercraft from 25 years ago, still on the water. I would expect many more years of service from your Jet Boat.
