With a surface prop its not out of the question.

I don't know much about hull design requirements to hit that speed, but I always thought the rotary would be an awesome conversion platform. I used to own a 1974 RX-3 back in the day, and I was running about 300rwhp from that 13B N/A PP engine. Used to get like about 4 miles to the gallon on it! I remember I would hit 10,000rpm on the after market tacho limit and the needle would still bounce with the engine still pulling. This ability to rev its nuts off tells me it would be a winner, but I am yet to see anyone prove numbers on water for a ski. I have seen turbo setups that are good for 600rwhp+ The rotary engine needs a light body as well, not much torque there it's all in the power to weight ratio. There has been a lot more success on boats >

I work on some pretty fast boats. 300 hp plus. And its hard to get 120 mph with a 21 ft boat much less a ski thats 11ft long. although the 13b is no joke I would like to see that ski hit a hundred! Atleast these guys are trying somthing different and its with a polaris hull!!!!!!!
