    Default Thermostat question s


    Engine is a Yamaha 25elrr.
    How long should the engine operate before it starts "peeing"?
    Air temp was approximately 65°f, water temp (muffs) approximately 75°f.
    Are these thermostat s reliable?
    Should the stat be removed?
    Does the engine operate better warmer?

    Thank you

    Should always run thermostats especially 2 stroke. Running to cool causes them to carbon up bad. Cooler weather they sent going to pee much. Just put hand in water if warm your doing good. Even a stuck open thermostats are better than none. Gives it some restriction and thus warm block.

    Going to overheat probably. But to date I have never seen one do it. Ones I have seen stuck are usually ones that have lost water, got hot and stuck open. Yet anything is possible.
