    Default 1992 Mercury 40 hp 4cylinder outboard cooling system

    Does this engine have a thermostat , I can not locate one on the engine and there is no reference to it in the repair manual. If it does have a thermostat can someone describe where it is located on the engine.
    Thank You
    Tony

    Doesn't have one. Overheating?
    Hey, Have you seen? They make Really Cool life preservers nowadays.
    So "Looking Dorky" is no longer an excuse for not wearing one.

    Actually was using the boat that day and ran very well. Trailered it back to the house and was flushing the motor when the water suddenly stopped pumping out of the weep hole. weep hole is not clogged, a friend of mine thought the thermostat might have locked up, then i began to look for it and can not find one. I have not tried flushing or running it again since then.
