  • Yamaha WaveRunner Compression Problem

    Hi so i have a Gp800R and it bogs down on the get up and it cant get over 6000RPM when its WOT and i got this for free from a neighbor and so i have no idea the history of what they have done to it but i do know it was in salt water before i can upload a video of it starting if it would help. i did a compression test on it and it was very weird it was 110-120 on the front and 150-160 on the back so i thought my compression gauge was wrong so i bought a nice new one and its on its way but if it is right does anyone have an idea whats wrong with it. It also shakes and rattles a lot and cant idle with out using the throttle a tiny bit.
