Kill Switch

[CaptainPuget]

My control box has the spring loaded button emergency ignition cut-off switch with the rubber suction cup like lanyard connection that is supposed to hold the button down. The rubber keeps popping off and killing the engine, most annoying. I ended up running back to the launch today with one hand pushing in the button and the other on the helm, could have used a third for the throttle. <br /><br />I don’t need or use or want this lanyard kill feature, my boat plenty safe without it. I’d like to disable it but I can’t find a wiring diagram that shows it. Does anyone know an easy way disable this button? The engine is a 1987 Johnson 70hp and the controls are 1987 vintage as well.

Re: Kill Switch

That rubber cap like piece was repalced long ago by a different style that works fine. Just have your Evin/John dealer order one. He probably has them in stock anyway.

Re: Kill Switch

That’s certainly an option but I’d rather just disable it and never have to worry about it again.

Re: Kill Switch

With the new stlye lanyard that Dhadley speaks of, you will never encounter that problem again. I strongly advise against disabling that kill switch function.

Cap'n,<br /><br />If you want to permanently remove its function, trace the two wires that join to it - black/yellow and black, probably - and snip the black one, sealing the end properly of course.<br /><br />This prevents the switch from grounding when the lanyard pops off. It's the grounding that kills the spark to the plugs.<br /><br />Not to be recommended, for obvious safety reasons, but that's the mechanics of it.<br /><br />Ciao
