Just bought a 2004 Seadoo GTX with a supercharger. Took it out on the lake for the first time on Monday. It ran great but the speedometer and fuel gauge quit working from time to time. The fuel gauge just disappears and the speedometer quits. I am new to jet skis but I do work on cars and pickups for a living so i have some mechanical knowledge. Just wondering if anyone had any advice on what to check. Thanks in advance
