Ghost starting on a 1997 150 HP

[Deleted]

When at idle, my 150 hp sounds like it is trying to re-engage the starter by itself. I hear a momentary "clank" noise, then it goes away. Also, if the motor is off, key in the on position (not start), it will occasionally start to crank momentarily. Is this a bad ignition switch?

If it won't try to start when the key is in the "off" position and only in the "on" position, I'd say yes...your ignition switch is shorting out.
