[Rhodes22-list] OB Motors ( for Rummy)

Wire nuts are not for marine use. I prefer soldered connections with shrink 
 tubing and then a layer of liquid electrical tape. I'm glad we dug a 
little  deeper into this subject.

Thanks  for the advice.  The nuts I was referring to are not the wing nuts 
on the  battery rather control wires from the outboard lift switch have wire 
nuts that  seem to come a bit loose every now and then.  I plan to replace 
them with  a better quality crimp but joint.

Strictly  speaking, wire nuts are not a good choice in a marine environment 
since  they do not form a gas-tight joint.  You should use solder or 
crimped  
butt joints for more trouble free permanent wiring solutions.  If you  wish 
to use wire nuts, simply make them gas-tight by adding a dielectric  grease 
to block corrosion during assembly of the joint.  Loctite  makes a good 
quality grease which is available just about everywhere (MSC  Direct is a 
great source for this, stainless fasteners, tubing,  etc,):
http://www1.mscdirect.com/CGI/NNSRIT?PMPXNO=3108381&PMT4NO=87953202

If  you are in a salt environment, stay away from the conductive 
"passivated"  
greases (zinc or copper added) as they have been thought to cause some  
galvanic activity that can degrade the wire joint.  They're also a  bit 
more 
costly.

If you want to try an old solution for the  corrosion that usually works, 
just paint some Vasoline around the joint to  block corrosive vapors.  It 
may 
not be hi-tech but it has worked well  for years.

Make sure that the wires are real clean before joining, use  a NEW wire nut 
and paint some grease on for protection and your joints  should last 
several 
seasons without trouble.
