First off you are using an outboard tach? If it has a setting switch on the back of the tach it should be set to 12P for the 75 HP Mariner. Also, you should have red wire to + and black wire to - on the back of the tach. The gray wire should be to the signal on the back of the tach. This wire comes from the rectifier. If all above is correct disconnect the gray wire and using a volt/ohm meter measure the voltage on the gray wire with the engine running and come back and let us know.
