Where to get mini jet boat plans i like the ten foot hull he make but if anyone can help me find some plans for a 11′ hull that would be great. thanks, mike. The dyno jet utilizes the popular jet pump powering system. there are plenty of "jet skis" that have suffered hull damage but the propulsion system is still in good. This patented design extends the boat’s keel and moves in perfect relation to the jet pump yamaha boats are proudly assembled by yamaha jet boat.
