Hello. My name is Tan.

Do you have a volt meter to do some voltage tests?

Turn the key to crank position and move the throttle handle back and forth in neutral position. Do this while key is in crank position.

Ok what engine do you have? Mercruiser 3.0?

Locate the start solenoid on the motor bracket just above the starter. Jump from the red/purple to the yellow/red. Does engine crank?

Ok the only way we can find the cause is to do some tests. This can be a bad key switch, bad neutral safety switch, bad slave start solenoid, bad start solenoid on starter, bad starter moroe or a bad wire. So we have to start eliminating components till we narrow down the cause. The most common failure is the slave solenoid.

If you can get a volt meter we can find the exact cause of your problem.
