I am re-wiring my Boston Whaler boat, and I want to replace the black-grey paired cable used for the navigation lamp circuit. I do not think the existing wire is pre-tinned, but I want pre-tinned wire. Where can I find a source for this wire?

Here's a good place to start: [link removed--vendor did not have the cable--jimh]

I have cruised through both of those sites before and neither has the paired black/grey wire used on by Boston Whaler for wiring the navigation lamps circuits.

Then get a black wire and a grey wire. Ancor makes GOOD STUFF
for the marine environment. Not cheap, but GOOD. REALLY
GOOD.

Boston Whaler has used a two-conductor paired flat cable which resembles "zip cord" and has black color-coded and a gray color-coded conductors. It is similar to the often seen red/black paired cable used as the power cord for many DC voltage operated devices.

The paired flat cable is handier to install than using separate cables. I, too, would be interested to learn of a source for this particular cable.

That is my plan-b if I cannot find the flat wire.

RatShack sells a 25ft roll of red/black 18gauge "2-Conductor Megacable". It's a zip-cord type arrangement.
It would probably work well for the nav lights. I've used it for general 12 volt wiring like instrument lighting and so on.. I keep a spool of it in my boat's "trouble box", handy stuff to have around.
Pt# 278-567 $4.99 in stock at most RatShack stores.

Boston Whaler did not use a two-conductor paired flat cable which *resembles* "zip cord" ...it *is* zip cord and is identified as such on their exploded parts diagrams. It is the same stuff your floor lamp is wired with and as such it does not survive forever.

I wish Ancor made a duplex 16 gauge wire that was small enough to fit inside the rub rail insert of a Boston Whaler, but they do not. It is quite bulky because of it extra sheath. You can just barely make 18 gauge Ancor duplex work, but it's tough.

What guage should I be using? I guess i will buy a spool of black and one in grey and just stuff them in next to each other.

George,

18 gauge is adequate but 16 gauge would be nicer and will be more durable and trouble free.

If you use separate wires, tie the ends off to something, string them out and then tape them together every foot or so with a little electrical tape. This will make it much easier to handle the wire when you wire up your nav lights.

Ancor has Red-Black duplex zip cord (ribbon Cable). Is 16Gauge too thick to fit under the rub rail?

To make your own paired cable, I have used this technique for many years:

--Unreel a length of cable for each conductor. Be certain that the conductors lay without any twists in them.

--Tape the ends of the two conductors together; place them in the chuck of a hand drill.

--Operate the drill slowly, twisting the cables together

Depending on the characteristics of the insulation, the cables will often lay into a nice twisted pair which will be easier to handle and route.
