[Rhodes22-list] OB Motors ( for Rummy)

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.
