I have this kicker motor with an electric starter. When the motor is in neutral there is a cam on the gear shift lever that activates a pushbutton switch that allows the starter to engage. The cam no longer presses down on the pushbutton hard enough to activate the switch and the motor doesn't start. I can press it down manually and get the electric starter to work. My question is what is this pushbutton part called? Is it the shorting switch?
