I would NOT use cat-5 cable for anything on a boat (Except ethernet
because I have never found a stranded TP ethernet quality cable)... it
is solid wire and I am not a fan of solid wire on a boat... use a
quality marine grade tinned wire. Most marine supply stores have a good
selection of multiconductor wire. BTW... I am assuming that the
existing wire is NOT coax... I have only seen a couple GPS units that
use coax...

I have a used raymarine GPS where the wire is too short.

I am wondering if I can use ordinary cat5 cable to replace the original
wire. It looks like the power is used carried on one of the wires.
