I have a buddy with a 22 Cougar MTR - top speed with a 300 x - 90 mph . We are at 1750 ft. He put a Nizpro 450 hp Supercharged Yamaha on it - first pass - 114 mph GPS. This speed was with stock Yamaha gearcase - no nosecone but water intake holes above centerline of gearcase were closed off. He was happy. I have twin 475 hp Nizpro Yamahas on a 25 Talon - in gear idle start to 100 mph - 10 seconds. No top speed numbers yet - the boat skates around over 105 mph - scary -trying to work it out.
