If you don't want to pay the price for the connectors with the self adhisive
sleeves, then use good quality marine connectors and purchase, sperately,
the heavy duty adhesive shrink sleeving..

I'm really sold on the heaver self adhesive shrink sleeving.. I get mine
from Waytek Inc, http://www.waytekwire.com/ Good prices but they have a
minimum order of $25..

Rick, you don't mention the deep submersibles method of routing nearly all

We only used oil-filled cables for temporary of field installed systems
that didn't rate a shop made cable. We would save the plug ends and a
foot or two of wire from old cables for that purpose. We used oil-filled
j-boxes externally and ran conductors through the same type of clear
plastic tubing you see in boat stores and filled the entire run with oil.

We had a shop back in the world where we could build and vacuum pot our
own cables for newbuilds. Some of our standard cables were manufactured
by a specialty cable shop. A lot of smaller stuff just used off the
shelf underwater connectors made for the commercial (oil field)and
military market.

I've used trailer wire connectors previously and they're certailny
cheap and available -



I have to rewire our mast (30 ft Al. Westerly Tiger) and also
completely redo the connection of the mast wiring into the boat.
About five wires and a VHF coax. All 'running' and the anchor
lights will now be on the mast.
A repair to our boat on behalf of the previous owner, following a
dismasting, by a presumably competent person, mounted two three
pin connector sockets flat on the fibreglass deck adjacent to the
bottom of the mast with wires through. Wires coming from the mast
plugged into those sockets.
Water got into the sockets and then seeped down into the wooden
deck pad inside the fibreglass deck under the mast step. Water
froze and mast step heaved and cracked deck. A mess!

An alternate that some Tanzers have used and seem to like: a "J" tube
coming through the deck near the mast (and protected by it). Wires can
be long enough to go to terminal strips. Some boats have no break in
the coax between the antenna and VHF -- the plug fits through the tube.
The tube can be heavily caulked, the wires have 3 less places corrosion
can form; Lots of benefits and few drawbacks or drips.

(I went a different route, but am thinking of installing a tube for this
spring.)

Rick,
Yes it can me messy, but I just wipe it with paper towels...the shop type.
Not that much is actually put on, just enough to replace air gaps when the
heat shrink, shrinks. This reduces the cure time as does the heat gun
shrinking the tubing. The stuff I got from the line men 30 years ago had a
strong acetic acid smell then, as it does now. I would not use it on a
connection needed for deep water, high pressure, or for anything needed to
last longer than a couple of years...tops. I use it on temporary
connections that I want to seal but still be able to cut open and disconnect
later. Remember I am not talking gobs and gobs of RTV, only a dab or two.
Forgive the non-tech measurements, but DIYrs will understand me...I think.

Incidentally, I just finished some life testing on a new series of coffee
pots, which I cleaned daily with 4% acetic acid (white vinegar). After the
equivalent of several years of accelerated testing, I opened the units and
checked. All my connectors and control panel enclosures which were sealed
with the RTV were fine, but the hose clamps were badly corroded from vinegar
steam leakage. I am not seeing any problems with the RTV corroding
electrical connectors or electronics boards on any of this testing or the
other testing which I have done.

I think I will set up some life testing in the lab and see if I can create a
corrosion problem with the RTV. I will let you all know what I find out.

That is incredibly messy isn't it? The adhesive filled heat shrink that

most wire jackets while RTV just won't stick well enough to depend on.
The heat shrink is self contained, no messy tubes, no rags, no drips or
blobs of excess goo ...

I bet you will have no problems with it. For years it has been a
standard to avoid the use of the stuff on or near electronic components
and boards but I have never seen any problems associated with it in the
absence of liquid water or very high humidity.

I will admit there are places where the stuff is very handy and useful
but years of seeing it fail in a marine environment has made me very
cautious about where and how I use it. Personally, I do not have a
single tube of the stuff on my boat and it is a fairly large and
complex old girl with a lot of external wiring with all the stuffing
boxes and penetrators that entails.

There are just too many better products available.

It should. We borrowed the techniques and materials from you guys to
begin with. 8-)

I love Scothchkote, it is one of those "electrician in a can" products
that really is worth its weight.

We tried all the prepackaged urethane and epoxy splice kits but never
had a lot of success with them since unless they were prepared in a
vacuum chamber like we did with the shop terminated cables, they were
susceptible to bubbles that would collapse under pressure and create
problems or even fracture the epoxy potted splices.

It was actually faster and usually more successful to hand splice
onboard ship.

an old VW fusebox, and wondered why connecting 12v to one LED, caused

When I lower my mast, I unplug the automotive ball connectors at

reconnecting them each year keeps them clean. The cabin overhead
connector is an empty shell, with only push connector wire ends
and a silicone rubber seal on the top of the mast tail shell
half. The connectors at the spreader are there so I could unplug
the spreader light assembly to lower or replace it easily if
riding the bosun. The spaced out connectors at the tabernacle
won't fit the bung all at once, and doing them staggered in
series keeps them organised. The wiring festoons the head
bulkhead join in plastic cable clamps with 2 screws each, one to
retain the mounting and one to release the wire bundle. The
connections to the mast can be seen belowdecks, and tested
easily. 5 years, no probs. The 'marine' plug connector fell
apart the first year.

We made up many of our own cables for submersible work and repaired

that supplied my life-support system a mile underwater I did not even
consider using a silicone sealant anywhere on the splice.

The only place we would use those sealants was to seal rubber gaskets in
on devices that were not subject to more than minor pressure differentials.


First, I don't call the forces that get water into your wiring in a

Second, a boater who has to worry about if his wiring will work 10,000 feet
down has other problems more important than some silly wires.

If a splice fails it will usually fail on or near the surface. Water
just gets in faster and further at depth, the damage it does to the
system is the same so it is well worthwhile to make your splices good ones.

If a splice fails it will usually fail on or near the surface. Water
just gets in faster and further at depth, the damage it does to the
system is the same so it is well worthwhile to make your splices good ones.
