Easy to assemble and worked great for my boat trailer! Compared to the previous one, this one runs smooth and the gear ratios make the difference! Many boat trips and no issues yet!

I recently purchased an older pontoon trailer and it needed a new winch badly. When I got this it made a world of difference! The ratchet system is nice and smooth and easy to use. It mounted the same way as my old one so just reused the existing hardware and only took maybe 10-15min. Well worth a weekend upgrade for anyone needing to upgrade there old winch. It came pre wound with the green strap so you don’t have to do anymore installation that just mounting the unit. As long as it holds up for some time I have zero complaints. Well worth it!

Why did you pick this product vs others?: Works great! My original boat winch had a wide spool for the strap and tended to drift and bind up. This winch has a more narrow strap spool and it eliminated that issue..Crank has better grip also.

I needed a way to load my UTV/ATV into my trailer by myself. I bought this winch and installed it on the front of my utility trailer. It is so easy to use. Just release the strap and pull it to the back to hook to the front of the ATV. Then you just crank until it's vehicle is on the trailer. Very impressed.

Winch itself is very sturdy and great performance but the handle is very weak and thin. During the first use I rounded off the slot that attaches the handle to the winch and bent the handle. Pictures included.

The media could not be loaded. Seems well made but definitely will rust if used for boats. Easy 3 bolt install. But Nuts are not secured by a pressure washer or anything. I recommend locktite or adding security washers to avoid getting loose with vibration. Locks both directions for forward or backward applications…. Even could be reversible if needed
