Just recently purchased a 2004 XP DI in Mint condition with a cooling issue. Looks like the previous owner ran the unit up on some mud bar on the river and sucked up so much mud into the cooling system that the resonator and the sensor on the water box melted. I replaced the resonator, the water box sensor, the hose coming out of the water box and the one going into the resonator. Then disconnected the intake hose at the pump and flushed out the system. I also found that the waterbox regulating valve was slighly melted and full of mud. Cleaned this up and all the mud in the cooling lines. Ran the unit on the hose wih no issues. Then took it to the river and it idled with no issues. Throttle response was great and it got up on plane like I would expect. The only issue now is that once on plane the warning buzzer went off with one loud beep, and the red light on the cluster came on. I immediately came off plane and idled and the buzzer went off and it idled fine. Does this have to anything to do with the computer thinking that the issue still persists? If so do I have to go to a dealer to clear the codes or is there something else going on? Any input would be appreciate it. Thanks
