    07 90ELPTO warm at high rpm

    Hello,

    Was wondering what you guys think of this? My BIL has an 07 90ELPTO and when running at higher RPM like 5,400 gets the high temp alarm. Seems to be fine putting around at 2-4,000.

    Forgot to mention it has a new impeller. Was thinking maybe thermostat?

    Thanks for the reply.

    I asked him that as well and his boat does not have a seperate pressure gauge. What function does the poppet perform? Allow coolant through the head?
