I've made the decision to convert to an electric winch...it'll be here in 2 days. Are there any special considerations when installing? I purchased a Powerwinch Model 912 here on iboats.
Thanks Dingbat. The rig in question is shown in my sig. I am generously figuring total loaded weight of 5-6K lbs and the winch is rated to 11,500 lbs. It comes with 50' of 7/32 cable and a block pulley. The only spec I cannot determine is the size and length of the power cords.
I've seen setups with the cables long enough to reach the vehicle battery and some that just hook up to a battery stowed in the bed of the truck. Would there any problems with mounting a battery (boxed, of course) on the front of the trailer?
The wire is permanently mounted in the trunk, and is run thru the car under the carpet, thru the firewall and permantly attached to the battery.
Just a tip on wire size, people underestimate what they need 99.9% of the time. If you aren't used to working with high amperage 12v electronics, the size of the wire might seem absurd! I can run an entire house off a 10 gauge wire, so why do I need a 2 or 0 gauge for a single winch?
Good discussion on wire size below... In general, 8 gauge is undersized for pretty much any winch if you are coming from the main battery. 4 gauge is marginal, 2 gauge will get you up to a 12k winch if the lengths aren't too long. (2 gauge wire has about 1/4 of an inch of copper, with at least that much cladding. For comparison, the total wire size is between a dime and nickel in diameter... Pretty serious wiring!
As someone above mentioned, you will kill a winch by underpowering it. (stall out and burn up) You won't ever burn one up from having too large of wiring though!

good points, Smoke, which is why play it safe and use the Powerwinch wire harness even though they are expensive. They come with big double fuses to be used at the battery end.
This discussion is precisely what led me to what Dingbat calls the jump box. I envision it being located at the base of the winch stand in a lockable battery box (heck, maybe a small locker for the battery and other accessories). This eliminates large, long cable runs...am I missing something? I have two chargers, as well.
Hopefully the wire is fused within 18 inches of the battery? I've seen more than my share of vehicles burn to the ground because of installs pretty much identical to the above, minus the fuse. It might be good for a month, year, or years, but eventually an aftermarket wire installed in someone's garage will rub through on a bare metal spot.
Although you can rig it to pull the boat off to launch, if you have rollers you won't need to.
