    Also do a search for air mods in this forum. With air mods and scom you will need a 14/21 prop. Those will give you best bang for the buck. 72 to 75 mph depending on air temps, humidity, etc.

    Hi what brand of SCOM did you put on your ski?, same thing has happened to Johns ski 300x here in Thailand put on a SCOM from Jet Ski World did nothing. I put the same brand of SCOM on mine 300x and my RPM shot up 400RPM Im really happy with my SCOM but my opinion is John got a defective SCOM as well.

    I ran one for years. However, many people advise against it. I also suggest just doing a scom as it is more consistent than spacing the wheel.

    either it was defective, or wasn't installed right. Mine went from 65 to 74.
