there are a lot of mods you could do. A ride plate is one of the best. Gets you to a plane faster and helps to keep the front end down (more water into the pump). Mine has fins on it and hooks up great in the tight corners. A scoop grate if you ride in really rough water (depending on how deep the scoop is it can cause drag at top speed and slow you down). A variable pitch impeller will help you to get out of the hole quicker and depending on what you select can increase top speed. The real key to these machines is moving the water through the pump. The engine mods will get you to top rpm quicker and increase the total power of the motor. Dont EVER mess with the rev limiter. A friend thought he was really smart until he jumped a big roller. Pump came out of the water with the throttle on and BLAMO! It was rebuild time.
