I want to install my battery in the bow of my 16 foot skiff. The
battery will power the starter for a 25 horse electric start
evinrude.
The total cable length will be 18 feet, no breaks. What guage wire do
I need to use, do I need to use something as big as a car like 4
guage, or can I use 8?? How many amps does a typical 25 horse starter
draw?
Any help would be greatly appreciated.

The wire should always be thicker than the largest drill bit you have on
hand to make the necessary holes, and all the stores are closed. It's
inevitable.

That would be some pretty big frekin' wire. I am a tool guy.
Anyways, I have some calculations here somewhere if someone can tell
me what that starter should draw... somewhere... Hopefully one of you
can just tell me what guage I should be using

Tom should be along shortly, although he'll probably suggest using frozen
quantum proton streams to move the power from bow to stern.

First, if the distance from the starter to the battery is 16 feet....
use 32 feet for your calculation.

You could probably get by with 4 GA, but for the difference in price,
I'd probably go with 2 GA.

BUY MARINE GRADE CABLE, BATTERY BOX, AND HARDWARE.

Do you have the tools to do this? You are going to need a heavy
crimper and a heat gun.... not cheap!


Bernz-O or someone makes an inexpensive butane torch about the size of an
electric toothbrush. Works fine with heat shrink tubing assuming 4 things:

1) No strong wind

2) Practice on a piece of scrap wire first.

3) Practice on a piece of scrap wire first.

4) Practice on a piece of scrap wire first.

Your buddy Tom should be able to tell you that. Somewhere he has my
phamplets for the starter motor he installed on the Johnson 25 on my
Princecraft.

Besides Gene's suggestion, this discussion may also be of some help:http://continuouswave.com/ubb/Forum6/HTML/000565.html

8 will probably do ok. but if you have access to 4 it would be
better. the brush leads in the starter itself, if combined don't equal
about 8 ga., so 8 will probably work, but 4 would work better.

Go to Abuchon's and get 20 feet of #10 zip wire. You don't need
anything larger than #10 - that starter doesn't require tons of amps.

Assuming you have a RV type battery, get 5/16 and 3/8 lugs - crimp on.

Get some shrink tubing for the lugs.

Get some acid free soldering flux.

Optional - obtain a circuit breaker panel like this:

http://tinyurl.com/2lnqz4

Run the wire, Install the shrink wrap, install the lugs, crimp them
lightly, solder the lugs, shrink the shrink wrap, hook up the circuit
breaker box (assuming you obtain one) and that's it.

No need for #8 or #4 - you don't have anything heavy enough on that
boat to require that.

Just Wait

For what?

Even for #8 Tom, tis best to have and not nead, than to need and not
have."

\However to eat my own words, I think that going "marine" this, and
"marine" that is a bit of over kill. I mean, I work around farm
machinery that sits out in the weather for years, and will take much
more of a beating than What that little skiff will ever see. And not
meaning to be offensive to anyone, but going to a marina to get
"marine grade" for this project is a bit overkill to the wallet
instead of hardware store and automotive parts that will function fine
with less pricing.

Tom, if 8 g. is too big, then go 10g. it's good for about 70a. on
12v . After all, the least it will do while cranking the 25 horse (if
having a hard to start spell). is slowly melt the insulation
off.. ?:
