Is there a source for the 3 wire coiled cable which attaches to the telescoping pole light in the console for the OUTRAGE models?

I am not familiar with this cable, but based on your description and a photograph recently posted in another discussion regarding classic Boston Whaler wiring, it sounds to me like you are describing a coiled microphone cord. Look for a replacement microphone cord or cable.

I tackled this project last year when I replaced this light. At the time I couldn't locate a source for the coiled 3 wire set-up from the factory. I re-wired with 3 wires and put it in spiral flex to keep all of the wires together. I lowered the mast to the bottom and mounted the wire bundle to the bottom side of the console. I left a little bit of excess in the bundle to take the strain off of the wires. I used the factory plug at the bottom of the tube so that the wires are fed better through the tube.

I just completely wired our 18' Outrage. I took an old cigarette lighter plug/coiled wire, that came from some old discarded electrical accessory, then tried that. The problem is that in the down position, the coiled cord is stretched. The stuff is designed to "rest" in the loose position and only stretched from time to time - otherwise it loses its recoil.
So I did away with that, and carefully wire-tied the standard 2 strand so it is taught when extended, and loose straight up when the light is extended.
Re: microphone cables - they contain at least 4 micro wires, very small, not designed for continuous feed of a light bulb. I'm not sure if they should be used to supply a halogen anchor light bulb - perhaps an LED bulb, but Jim H might be more up on that.

The gauge of the wires in a coiled microphone cord varies from brand to brand. Look for one similar to the model used by Broderick Crawford in the television show HIGHWAY PATROL from the 1950's. The wire would probably be 18-AWG.
I concur that some modern coiled cables may have a type of wire which is formed with a tinsel type conductor and a silk strand. These are used in telephony applications, not radio applications. Avoid those sorts of cables. I was looking for a good BELDEN part number to reference, but so far I have not located the proper product.

Make your own cable. It is not hard. Here is the process:
--obtain a suitable length of 18-AWG wire, preferable with black insulation and another with red insulation;
--cut four length of wire, two with red insulation, two with black insulation; make the length about two-times longer than the length you need;
--fix one end of the four wires in a vise or other stationary clamp;
--stretch the wires out, and place the other end into the chuck of a variable speed drill motor;
--applying some moderate tension on the assembly of the four wires, operate the drill motor at low speed and wind the four wires into a twisted quad cable.
By using four wires in the cable you will make a twisted quad cable which will have a very nice lay, much smoother and more stable than a twisted pair cable.
--remove the cable from the vise and drill. There will be some relaxation of the twist, but not too much (unless you happened to use wire with Teflon insulation or another type of insulation that is very resilient).
--cut several short pieces, about 0.5-inch in length, of heat shrink tubing of appropriate size to fit over the quad twist cable. Position the heat shrink at intervals of about 6 inches. Use a heat gun to shrink in place.
--strip, twist together, and solder the two red wires and the two black wires at each end
You will have made a nice quad twist cable which can be coiled around the pipe or post of the navigation lamp fixture.
If you need a three conductor cable, use a third color in place of one of the red conductors. The four-wire quad-twist cable makes a very stable and easy to handle cable. Four wires lay in a twist more uniformly than two or three wires will.

I have an original coiled cable from my old Outrage 18. It was removed in 1989 after six years in the boat.
Would you like to have it?

Speaking of wiring for this light pole, I'd like to leave mine out under normal circumstances (we don't go out at night much). Can anyone recommend a plug (brand, model number, where you got it) that could be used in this application? It would have to fit through the hole in the top of the console.
