Find the 2 small black wires that go under the flywheel.----They are usually connected to a stop switch.----The circuit is CLOSED to stop the motor.-----

Just like a lawn mower there MAY or may not be a kill wire on the coil packs. I checked Iboats and there is a SHORTING switch. Do you have a kill button or a stop button? if so you can setup a lanyard with a kll switch and when the 2 wires to the switch connect, they ground and stop the Magento/Coils from msaking spark. Not suprt easy but possible with some inventive shopping.

If you have to Insert the kill switch into the hole in the console, from the back side, and secure in place by screwing the attachment ring onto the threads of the kill switch bracket. Tighten the attachment ring in place with the pliers. Secure the spliced wires with the wire ties and reconnect the negative battery cable. TellTims Survey
