    Mercruiser greatly overpropped, need advice

    Thanks, then you need to reduce pitch. With compression gauge being accurate, there is some kind of liquid in the cylinders (gas, oil, water or carbon build up)

    Disconnect the purple wire going to the coil on the + side, this removes power so there will be no spark Open throttle wide open and leave there until all cylinders are tested Have it crank over at least 3 times for each cylinder

    Mercruiser 6.2 cool fuel pressure

    The pic is just a representation and is not used as actual. Check the return line at the filter head and make sure its not plugged If its all good, then it has to be the regulator. The pump will pump 100 psi, but if the Reg see's anything above 60 psi or so it breaks the Reg.

    alpha 1 Gen 2 sterndrive broken lower drive shaft

    SEI doesn't make a B3, Merc still has patent Its unusual even for a heavy boat to brake in the same spot other then over loaded. Might think about changing ratio to a 1.80 or 2.00 to reduce stress
