    08 GP1300R over heating

    I have a completely stock 08 GP1300R. It has about 50 hours on it. The last time I was on the water I overheated when I was going about 40-50 MPH for 5-10 minutes at a time or so. This happened about 5 times though out the day. Each time I'd slow down for a little to take load off the engine and keep water running over it, and then shut down and restart to reset the alarm. This worked except for one time it came back on with the alarm going off. Every time it was over heating it showed it was the exhaust sensor. However 2 or 3 of the times it was showing the engine also. I checked the intake it seems clear. Could this be the cat failing? I was thinking about putting a d-plate on but was worried about why it said the engine was also overheating. Whats the best steps to take when on the water and the overheating alarm goes off?

    Check the cooling line intake for blockage. Is there water coming out of both side cooling outlets "pissers"?

    Yeah there is a steady stream water coming out of the outlets. Thats why I thought it may be the cat, but the two engine warnings have me a little confused.

    You need to pull the exhaust pipe off and check converter both sides. pull it all the way out to make sure its not melted. and if its broken up make sure to get all the pieces out of the water box. that would be a good start.

    Followup to this issue.

    I have been playing with it off an on. I finally removed the cat and put in a d plate. However if i'm running hard for about 10-15 minutes I'll get a warning with the beep. It flashes both the check engine light and the exhaust over heat light. If I restart it, I'll just get the exhaust over heat warning for a while. The sensor is still in the exhaust but I think it may have been damaged since the cat had broken out of its holder and was jammed up against it. I think the sensor is suppose to go straight into the exhaust, but now it is bent and pushed up against the pipe. What should I do about this? New sensor, resistor instead? Can I be causing any damage? My understanding is that once the cat is out their is nothing in the exhaust that can really over heat.

    Yes. It can melt the rubber connections and hoses. Then your ski gets flooded from the water in the exhaust lines.
