    Re: Powertrim Issue

    It maybe internally leaking. Unless you an find a hydraulic place or a good marine shop to repair it. May just as well get another used or new one. These trim pumps can be costly to fix.

    Re: 2008 Mercury Optimax 150 alarm

    Try disconnecting the oil tank sensor and see if the problem goes away. If it's still going off there may be a sensor for the oil pump also. Also try disconnecting the temp sender too. .
