    15 FZ high temp alam ONLY ON LONG PULLS

    Stock FZ WITH SCOM I can ride around all day no alarm but if I do a long pull It will alarm and go into limp mode. I cleaned the thermostat and it did the same thing. I think it always has done this but after a pull a little steam floats up from the water even on a 95 degree day

I have changed my plugs and battery and get full flow from my pisser and when I’m flushing my outlet of the t stat? No milky oil and ski runs 73 with scom
    Seabrook do what I do, install a temp gauge. I run with mine all the time. This way if it does go off on temp you have an idea of what it is. I would first remove the stat and ride it for just a day.

    Lazy t stat
    a restriction
    Bad sensor at the exhaust
    Corrosion in the head or exhaust manifold
    Clogged strainer
    clasped hose

    take care

    Remember this is just a temporary fix to see if the problem goes away or not, you don’t want to have problems with gas in the oil or anything like that. If the problem seems to resolve itself with the thermostat out, I would look for something like corrosion buildup in the exhaust manifold or a lazy thermostat.Good luck to you hope all works out.

    Did you give that ski a ride without the thermostat to see if that would solve your problem?I think your problem at wide open throttle is that you can’t dissipate enough heat and the sensor is just doing its job.

    I would first check for corrosion buildup in the exhaust manifold or sediment at the bottom of the engine block like sand.

    I don’t think that engine will have a temperature higher than 140 discharge from the thermostat. The only way you can know for sure is to install a temperature gauge.

    no lol thanks man! I ordered a new tstat for piece of mind after that I’ll start replacing the sensors. I was wondering if I can take out he tstat and spray water in the head without it effing something up??
