    Disappointing thermostat for 135-150HP Mercury engines

    This thermostat may seem like a good deal, but don't be fooled. I installed it on my boat and noticed it wasn't accurate from the start. It caused my engine to overheat, and I had to spend more money on repairs. The quality of this product was terrible, and it wasn't worth the risk.

    Pros
    • Price was reasonable
    Cons
    • Didn't work correctly, caused overheating

    Warning DO NOT BUY: Engine Cooling and Climate Control

    They were supposed to open at 143 feet, my thermos in my boat rose to almost 200 feet and nearly destroyed my engine. I had to turn it off for about 20 minutes to let it cool and then head back to the pier and home. A piece of poor quality product. DO NOT RECOMMEND. I took the thermostat off the engine, put them in a pot and heated them to 143' and they didn't open at all.

    Pros
    • Temperature range 143 degrees
    Cons
    • Disappear

    DO NOT use in Mercury Optimax outboards

    So I bought two sets of these gaskets. Installed on my two engines with new water pumps. Heating problems started. I looked at everything else and then finally took them out and put them in the pot and they don't open until 147-148 and when I say "open" they start to open VERY SLOWLY, never opening fully , even at 180 they are not fully open. So don't use them. And of course I can't return them now because it's been too long. Full of BS.

    Pros
    • Gasket kit 310058
    Cons
    • There are new competitors
