I just bought two 05 seadoo's, one a rxp and the other a rxt, both have about 25hrs on them. I replaced the ceramics with riva metal washers and when i checked the clutch slippage the rxp was reading higher. The rxp has a flat nut and the spring washers were more compressed. The rxt has a half flat nut and the spring washers had more gap in them, the rxt gear assembly also seems farther from the sc houseing than the rxp. Can i just torq down the rxt more? do i need a shim? or a new washer?
