I take it the red wire comes from the battery and the black one goes to the starter motor. The yellow wire is the active wire from the ignition and the blue one one bolts to the block? To start with I would put your jumper cables across the red and black fat cables it will spark at you pretty good but the motor should kick over. If it doesnt then the feed to the motor is no good. When you hold the starter in the turning over position there should be 12volts between the yellow wire and blue wire. There should be zero volts between the red and black when in the turning over position . Every chance its the solenoid Ive replaced a few on the different mercs Ive had. They click but the contacts get that corroded they dont work.
