    Like member MUC (retired marine Master Tech) here has said many times. Getting and paying for a Tech that knows what their doing is expensive, but most times it will cost less to use them then someone who thinks they know what the issue is

    Its some kind of stain. I'm rebuilding a 7.4 and it has the same white color under some of the spring areas. Might have been done during manufacture but this motor is a Merc REMAN be rebuilt again

    As MUC said, you have to get a Mercruiser Dealer ask Cobalt for the file Most hulls are made for many years, so a 10 year old hull may still be made today

    If its a switch then when motor is OFF a ohm meter will read zero ohms from center condictor to ground. If its a sensor it will read around 30 ohms to ground.

    seriously need some experts help on this one, no water exits manifolds

    You have MPI motor and without the motor getting up to temp it will be supplying more fuel then it needs. What that can cause over time to other items in the motor (sensors, excess carbon build up, other stuff) is unknown. Like running a motor with the choke partly closed Might not do...

    Oil pressure gauge wiring

    Yes lights only. so its just a switch connection that the ECM switches a ground ON I don't believe that will work. Found a wiring diagram for a Optimax and its labeled "light". Merc colors try very hard to not mix them into doing different things on another motor That may work because Merc...

    Electrical Issues after replacing trim switch/sensor 7.4 EFI/MPI

    Thanks, MEFI 1 with VST The MEFI 1 is not very smart, but could be a voltage issue. Check with it running to see if your getting 14.5V from the ALT with motor above 1500 or so rpm. Can scan for codes using a 12V resistor LED or multimeter with a tone function. Insert paper clip, turn key ON...

    I Bonds

    The Bonds are high because the Fed rate is up. Buying them doesn't mean folks continue to get the rate, as Fed goes up and down so does do the Bonds. Highest rate savings account is still Marcus at 1.2%, local is still 0.1. Marcus raises rates as the Fed rate goes up and many times in the...

    Engine wont shut off with key
