Yamaha 225

76 mph according to Fountains brochure. And I think that is a fact too.I think they have 1,65:1 gears on that package, at least that is what they did on the 35 Executioner to help acelleration. To get more speed, both the lowers and the uppers will have to be replaced. I know a few who use them just for cruising, and than it should work ok, but my opinion is that No6s is the only way, especially for offshore conditions. 2x1000 hps and the package is complete, and after 10 years, it will still be a cool boat.

Good luck!
