Outboard battery cable extension
Roger Williams
I need to extend the battery/starter cable on my yamaha 9.9 four stroke
by about 8 feet. I think the existing cable is 6 guage but I am not sure.
Any suggestions on what size cable I should use for the extension and
also any ideas on how to make the splice?

the harness of the Yamaha and joined the cables with a very heavy duty
soldering gun (250w?) and cored solder. Two layers of shrink tubing (put
on the cables before you join!) I staggered the splices so that the joins
were not next to each other, just in case!!! The splices were
mechanically quite strong using pliers and elbow grease. The solder merely
assured low resistance. All finished it looked ugly but lasted years.

another 8 feet of 6AWG cable should work just fine. You can buy some but
splice connectors for this kind of wire from West Marine. You need a
nicopress took to crimp the lugs however, and heat shrink tubing to
protect the splice. You might disconnect and bring your existing cables
to West marine. They are usually helpful, and may splice the new cable
on for you.

Why bother with a splice ?. Measure out the length of cable needed (6
gauge should be O.K. up to around 15 feet) and replace with new cable
complete with shop crimped ends. This is neater and safer as you can
be sure if no water ingress. I apreciate it is possible to make a
strong waterproof splice but as has been said it is ugly, cumbersome
and you can never be really sure of it.

The farther you are away from the battery the larger cables are necessary
or they will heat up and loose voltage. In your case that engine does not
need or put out much amperage but I would use #4 or #2 tinned cable.
Spice it together with a small piece of copper tubing crimped with a
crimpace or a large crimper for bat cable. Buy some heat shrink tubing
of the heavy kind and shrink it over the splices. The size tubing depends
on the size wire. Closer the better. #2 uses 3/8 refrige tubing for a
splice. If you are in my area we can make you the extention if you can
bring over your engine.

Bonnie has obviously never examined the 12v. cable connection to a Yamaha
outboard. It is very water tight to the engine chassis and the cable
inside the engine cowling goes a very precise route as it also carries the
charging current back to the battery! Do not attempt to replace the cables
inside the engine cowling. Do a splice, it's better than a non molded
entry to the casing!! If you don't like splices, (who does?) try to get a
replacement harness from Yamaha with the requisite length of cable. Before
you do this, you may have to search the Net for a d.i.y. bank-hold-up
kit!!!
