Re: mercury trim sender unit location
It should be located (if looking at the back of the motor) on the left side. Trim the motor all the way up and look where the center trim cylinder connects to the motor at the top. The trim sender is mounted to the end of the pin that holds the cylinder to the motor. It is black and has two screws that mount it to the side of the motor bracket. There is also a wire that is mounted to one of the screws (ground wire) and the other one has a black plastic wrap that goes to the motor harness for the gauge. Hope this helps. <br /><br />PS If you use the motor in salt forget replacing it they don't last long. Very poor design!!!
