    High Temp Alarm Gibson

    Out on ski last week all running great:

    Fitted Gibson exhaust with new T and even with tap closed get a high Temp Alarm at WOT .
    Have not yet drilled out the pisser holes?

    What is the Cure drill out the pisser holes have read about fitting a resistor in line but dont think this is the cure ?

    External intercooler is clean also the filter so it has to be water getting to the gibson or lack of.

    Have just taken off a gutted OEM box that worked fine but on the oem boxes the temp sensor is on the outlet not on the inlet to the box?

    Thanks in Avance

    Steve

    Speck as follows :

    Riva Ecu 50Ib injectors
    Valve train upgrade
    Rotax wheel
    External intercooler
    Gyco water strainer
    Riva 3inch intake inside
    15-19 with stainless liner
    81mm ring
    Riva pro series block offs
    Riva grate
    Jims Plate

    I have no idea. I just installed my gibson, drilled pisser holes to 1/4 inch and ran water to gibson from bottom of j jpipe. I ran ski hard for 2 hours this past weekend and with or without water feeding gibson i never did have temp sensor come on. In fact i could grab the j pipe with no problems.

    +1. never had a temp problem.Check and make sure that your coupler and clamps are not blocking the flow of the pisser holes.

    +1 to that advice, i forgot about that. I took alot of time to be sure that the coupler was mounted correct on j pipe without any blockage of pissers hold as speedskixp indicated. tighten up the coupler on j pipe before installing j jpipe so that you can get coupler as needed. Then when you fit the coupler onto gibson be sure all is lined up nicely and that you dont put coupler at too much of any angle that could prevent pisser holes from being blocked.

    Thanks for the advice

    Checked pisser holes with pipe and clamps all looks good so i think i will drill the pisser holes out and try first.

    The J pipe does not feel hot when you stop or the Gibson , so hope the bigger holes will help

    How much did you cut of the J pipe end where it goes in the Gibson from the flange where the pissers are how long is the pipe lenght left.

    So i can see if i have cut it correct

    Thanks

    just sent you a email steve. on any exhaust system from seadoo the temp senser is on the outlet. on the gibson it is on the inlet closer to the heat from the engine. we have found that by drilling the holes on the pisser to 1/4 it cures the problem. it's just that water may not be touching the senser to cool it.
