the black/yellow when grounded anywhere should shut off the motor. make sure your gound wire and that your black/yellow are good to the motor. you can take a wire and short the black/yellow to ground on the power head and see if it shuts down correctly. if so look at the wiring cable for issues. you can use a remote starter button like the one here in the pic i made. it works both as a starter button or clip on and use as a kill button.

so the key switch when shut off grounds the Y/B wire and this cause the motor to shut off. Great!!

Did I say I know nothing about wires!! and I have never been lucky with them! :-[

So I guess this is what I am looking for someplace??

that is the safety neutral switch on the V6 shift rod. the yellow /black goes into the brain on the motors.

Brain, you mean under the flywheel?? So I should look up there?
I was looking there today but after the wire harness I did not see the B/Y wire any were??

I am so confused :'(

And its not even mine!! Gee what I will do just to beat you guys in the fishing tour!! ;D

well I guess this is good practice as I never know what my next motor will be?

I got this from the guys on Iboats:

what makes her shut down: the keyswitch connects a kill wire originating from the powerpack(s), black with yellow tracer, to a ground wire, black.

The keyswitch has two terminals marked "M" - one with the black and the other with the black/yellow...when the key is off, those two terminals should be connected.

The emergency kill switch, which you should have one of, by the way, does the same thing, grounds out the kill wire.

Another way to shut it off is to flood it out by pushing the key in to activate the primer.

Assuming your new keyswitch is hooked up right, the kill wire must have become disconnected or developed a break inside the insulation somewhere between the powerpacks and the keyswitch. Could be the ground wire I guess, but then it should have no effect on idle speed.

I'm guessing by the change in idle speed that one of the packs' wires has got disconnected somehow, so you're shutting off one bank of cylinders but not the other.

To find out which one, use an insulated spark plug boot tool to pull a spark plug wire with the engine running and the key off. If the RPMs drop noticeably, then that cylinder is still on. If it doesn't change, then it is off.
-----------------------------------------------------------------------

I had the same exact thing with my 200 Evinrude. It turned out to be the exact thing mentioned here. I tracked the yellow and black wires from the power pack and sure enough there was a connection off. Reconnected it and everything is perfect now.

-----------------------------------------------------------------

Now if I can figure out what the hell they are talking about??

So each power-pack is wired into the key-switch... :) ...

Skools Out · #17 08-30-2006, 11:26 PM

in the newer OMC they have 1 power pack.

macojoe · #18 08-31-2006, 12:24 AM

I belive that after looking at mine I have 2 power packs.

But they look solid?? so how can I fix the wire?? I can make sure the grounds are good, but what if its in the power pack??

Does that mean he needs a new power pack??

Do they coast alot of money??

reelapeelin · #19 08-31-2006, 09:03 AM

MJ, I've bought a few OMC power-packs...don't recall price bein' too bad and that was thru dealer...you might be able to google up some savings ;) ...

Yea I looked on ebay for him and have found them for $20 mor less, just have to see what ones he needs??

I found one number for sure, but I can tell they are both different so i will have to look at the ones he has.

Have to ck wires with a meter first to make asure that they are good first.
