    Thermostat for HOT weather

    I run in 35++ degrees celcius(95 deg F) when i'm sking and notice a lot of heat fade, ski pulls like mad for the first 10 minutes of so then fades away 300-400 rpm, could changing to a cooler thermostat or removing it compleatly help?
    Or should i be looking at ways to get the hot air out from the engine bay?
    any help or ideas appreciated(ski is a 03 gtx sc, stock)
    thanks
    Ben

    You need to do both.. ways for airflow and a 160 thermo. Do some searches in the seadoo section should help yah out.

    Yes you can run a cooler thermostat,most run the 160 degree with no issues,but there is also a 131 degree which IMO is a tad to cool for our everyday conditions..As far as ways to evacuate the heat out of the engine compartment? This can easily be done by installing a 3 or 4 inch bilge blower and a couple of flow rites.....use the blower to pull cool air in and the flo rites as the place the hot air escapes..

    I have a spare 160*F thermostat compete for $75.00 plus freight,
    I made 2 of them for my 2006 RXP race ski, I put a S/S clamp around the notched grooves for added piece of mind,
    Sorry about the gauge picture that was for my RRFPR,
    thanks,

    Can you get a bilge blower and flow rites in the online store? or are they easy enough to get from local shops? My local dealer here in Australia seems to have NO IDEA when it comes to buying that sort of stuff, they like to sell brand new skis and thats about it i don't even like taking mine to them for maintaniance.

    I don't understand how the thermostat has any relation at all to hot weather. Can anyone elaborate why you think it does?

    Having the thermostat open earlier helps keeps engine water temp down, it gives more time before it will get too hot, It's harder to heat water/coolant from 55degC to 90degC than it is from say 75 or 80, if any of that makes sence? at least thats how it has been explained to me.
    Although i begining to think a lot of my problembs are with heat in the engine compartment and not getting enough cool air into the motor.

    Lower temp thermos help reduce the operating temperature of your engine,lower operating temp can help lower engine bay temps...
