Take the strain out of loading and unloading your boat with this electric winch, featuring a Load/Unload power switch and a freewheel clutch. This DC-powered winch is designed for boats up to 9,000 lbs and has a wiring harness for installation.

Specs:
A common ratio for determining your winch load capacity is 2:1. For example, a 2,000-lb boat would require a 1,100-lb winch. There are extenuating factors, however, that will determine the appropriate winch size for your purposes.
The ratio can be stretched to 3:1 in instances when the trailer in use has high-quality rollers and is most commonly used on ramps where boats float most of the way onto the trailer.
In contrast, using a boat trailer that has wooden bunks, lacks self-alignment capabilities, and is most commonly used on ramps where the boat must be winched most of the way onto the trailer reduces the ratio to 1:1.
Note that pontoon trailers and other special designs require special consideration when determining winch capacity.
| Percent Incline | Multiply By |
|---|---|
| Level Surface | 10.0 |
| 5 (3 degrees) | 6.67 |
| 10 (6 degrees) | 5.02 |
| 20 (11 degrees) | 3.40 |
| 30 (17 degrees) | 2.61 |
| 50 (26 degrees) | 1.86 |
| 70 (35 degrees) | 1.53 |
| 100 (45 degrees) | 1.29 |
To calculate your winch's rolling load capacity - the amount of weight it can pull up an incline - you must multiply the winch capacity by a factor determined by the degree of the incline.
The multiplication factor shown includes a 10 percent rolling friction factor. Note: A 5 percent - or 3 degree - incline is a 1/2' rise in 10'. Follow the chart to determine your winch's rolling load capacity.
All Dutton-Lainson StrongArm electric winches are built for multipurpose hauling and pulling operations. They are not to be used as hoists for lifting, supporting or transporting people, or for handling loads over areas where people could be present.

Great on a boat trailer. Makes loading a breeze. A wireless remote would make this winch even better. Currently in use with a 19 foot Lund boat on a Shorelander roller trailer.

So far so good used @ 10 times and no problems pulling my 8000 lb. fish boat. The provided wire harness had to be lengthened to function but who cares the winch works great and a strap winch is the ONLY way to go with a boat of this weight.

The freewheel option allows the cable to be removed by hand. You will have to make sure that it is in the correct position to use the free wheel. If you have tried to manually adjust it and it is still not functioning properly, this item has a 2-year warranty.

DuttonLainson is a quality product, is my second one, first one went 15 years in salt water conditions. E-Trailer was excellent to deal with. One thing, dont care for the strap, switched to cable.
