Mercruiser Throttle Kill Switch (Installing Fell Marine Wireless)

[OllieC]

Good Morning. It's been a while since I've posted (Sunday confession)

I have a 2005 Sea Ray Weekender with a 5.0 MPI Mercruiser/Bravo 3 Sterndrive. I am in the process of installing a Fell Marine wireless kill switch inline with my existing kill switch.

In the installation instruction it says look for the yellow/black and black wires coming from the kill switch. Fell Marine also says Mercruiser is "close to stop", meaning the kill switch cuts off power to the engine.
However, all I have are 2 purple wires. I believe 99% those are it.

I tested the purple wires and in doing so, flipping the kill switch to 'kill', with my mutlitester set at resistance, the numbers were jumping all over the place, which meant to me, the wires or kill switch was, "open to stop"

Of course the engine isn't shutting off with the Fell Marine wireless setup, and I have swapped "open to stop" and "close to stop" on the Fell Marine side. The manual kill switch still works.

I'm not looking for help with the Fell Marine (unless someone has experience with my situation), I just wanted to verify that the 'purple wires' are the correct manual kill switch wires for my year of Mercruiser - or if it is one purple wire and maybe I have to tie the other with an ignition wire (yellow/red)?

Thanks,
Ollie

Ayuh,...... Mercruiser Ignition wire circuit is the purple wire,.....

Donno what the Fell switch is, but to kill the motor, you cut the power to the purple wires,.....

mercruiser kill switches go open to remove the 12v going to the ign system and what would possess you to install this on a boat? Unless your going to be wearing it ,a lanyard will accomplish the same thing

Thank you Bondo. That's what I figured. Fell Marine makes a wireless kill switch that you splice in line with your existing kill switch. This way you're not limited to the length of your tether. If you go in, it activates the kill switch. It works up to about 30' or if you go in the water.

BT Dotur - Sometimes I'm out alone on Lake Superior trout fishing. There's been a couple of times while trolling, I'm holding a fishing rod in one hand, a net in the other, while leaning over the side of the boat, and have had minor slips. I didn't want to be floating in the lake while watching my boat drive off to Canada.

safe boating is like safe sex, never go it alone

Nothing is safe, only safer.

To close this out and a FYI, I Contacted Fell Marine. For the purple wire Mercruiser Kill switch Setup, the wireless switch needs to be wired in series, not in parallel like I had it.
Thanks again for your help.
