Works great! The only thing that would make it better is to make the tensioner knob easier to grip when your hands are wet



by:

Just got installed so haven’t been to the lake to try it. I’m hoping it will make it easier to recover my boat when I’m by myself.



by:

Item was shipped extremely fast. Installed it shortly after delivery and all is perfect so far.



by:

The trailer winch is a huge help in allowing me to load my boat onto my trailer, especially this year (summer 2022) with water levels in most Minnesota lakes very low. The low water levels prevents the boat from floating up on the trailer in many cases - Muscle is required to pull the boat onto the trailer. This electric winch provides the muscle and saves my 65 year old body from the task.

I power the winch with a 12 volt jump starter and I've used it approximately 60 times thus far without problem. I keep the jump starter in the back of my SUV and then hook it up when I'm ready to load my boat on the trailer. This saves the trouble of wiring the car for the winch and it works perfectly.

Why 3 stars? Because the wiring at the connection from the remote cable to the winch was poorly done and failed within 1/2 year. I had to redo the 3 connections at the end of the remote cable and the 3 connections going into the winch. Very poor job by Dutton-Lainson connecting the wires to the connectors - Inexcusable for a $500 item.

I had a couple questions while installing the winch and etrailer was very helpful in answering those questions. This is why I buy from etrailer and not elsewhere. They both charge a similar price and the technical support that etrailer provides makes it a no brainer - I will always buy from etrailer.

I had to grind a little bit off the gussets on the mounting plate on my Tracker trailer to mount the winch but the bolt pattern was perfect. The electric cable that was provided with the winch wasn't quite long enough for my 4 door F150 so I used my wife's Explorer with the cable provided and got a longer cable and fuse for my pickup and then put a plug at the rear of both vehicles and a plug to the winch so I can use either vehicle. The winch pulled our 16'Tracker boat up on the trailer easily and I discovered you had tighten the gear locking mechanism quite snug or it would slip. I noticed the pulling belt on the winch is not quite as heavy as the one on my hand winch and I plan on swapping it out. Other than that, I am happy with my purchase.

Installed cables. 35A breaker is not insulated and required additional cable to connect to modern battery terminal - so had to buy an insulated breaker. On first use, the small gear on the motor drive shaft fell off because it was installed at the factory without a snap ring. Luckily I found it and fashioned a snap ring for temporary use to load the boat (see picture). Then learned the clutch was set excessively low - would not pull anything close to 1000 pounds. Manual says to not adjust clutch more than 20 degrees, but that would not pull as much as a 2000 lb ratchet strap. I see the other good reviews on this product, but clearly mine was built with some serious QC issues. Hard day on the boat ramp. Grateful for the help and patience of fellow boaters. I am beyond the 60 days to return this product since I bought and installed it over the winter to enjoy this boating season.



by:

Shopped around a lot before I bought this. My boat is heavy (7500 lb) and the wench I had struggled. I took a chance on this as it was rated for the weight. I used the Anderson style connectors and installed a breaker near the battery. Pulled new wire rated for the amp draw. I couldnt be happier! This thing is a beast! Has no prob pulling my boat and cant see that it struggles at all. Highly reccomend. Photo is during installation. I put a cover over it due to my anchor comes close when launching and didnt want it to hit.



by:

The product is great. I replaced a 2001 Strong Arm with this 2024 Strong Arm on my Floe Vertical lift. Having the remote control built in is very nice.



by:

Works good. The cable unravels and creates a little bird nest if it doesn't have tension. A strap would be better, but more prone to breaking I suppose.



by:

Works as it should. Mounted it on vertical pwc lift replacing handwheel. Has pwc up in 30 seconds. Was easy to mount with just two holes. Switch requires some force to operate but not a big deal. Would definitely recommend this for this type of application.



by:

They were exceptionally helpful in deciding which winch to buy. I got this for my pontoon boat on a slide bumper trailer. I wanted to make sure it would have enough power to pull my 24 ft pontoon. This winch is honestly one of the best purchases I have made for this boat. It easily pulls my boat up onto the trailer. Total time to load about 2 mins. I have had many envious looks at my electric winch. Thank you again. For the help in deciding which one to get.



by:

I purchased this winch to replace a Fulton K2550 manual winch on my ham radio tower. My tower is 54 ft tall when extended and 21 ft when retracted. It takes about 170 turns of the winch to raise/lower the tower. I removed the hand winch and placed the D-L SA9010AC winch in the existing mounting holes. I like this winch since it comes with a stainless hub since it will be used outside. This winch has a 2700 lb load rating. I am lifting around 700 lbs. This winch comes with no cable or freewheeling clutch. I reused the 1/4" stainless cable on the winch. I raised the tower and it took 2 minutes and 10 seconds. Lowering took 2 minutes. Well within the maximun run time of 3 minutes. The cable length winched was 17 ft. I have raised and lowered the tower several times to work on the antenna's and it worked properly every time. Attached are several pictures of the installation. I already recommended this winch to another ham operator.



by:

Works great, fit my trail weight boat trailer, with a 24 foot pontoon



by:

Received the winch and all looks good. I ordered a new boat trailer so the winch hasn't been installed yet. Will let you know when it's installed



by:

E-trailer service team, Lauren, was excellent. When my critical delivery delayed she came up with several options to get me a new part on time to support my need.



by:

Put this winch on my Ranger 620 boat trailer a year ago and love it! Haven't had a single problem and it helps trailering when I fish alone. I ran power and ground from my truck battery to a back bumper plug, and have a separate removable cable (shown in pic) to connect truck plug to the winch plug. Grounding to the truck didn't work for me. I have another spare cable and plug rolled up and attached to my trolling motor battery for when my buddies drive. Winch prevents power loading and drawing sand into the motor. DL24055 adapter plate was needed and I put a coupler lock up through the middle of the winch to prevent theft and I bought a cover (shown in pic) to keep the rain out. etrailer sales and support are absolutely fabulous! They helped me figure all this out.



by:

I love the winch for the strap is a great upgrade than the power winch with metal cable which would rust, wire strands would break off, and cut your hands, and the cable would not retrieve back on winch even. The cons I see is the strap has become dried out after use on the end at the hook and it wants to double over on same area. Another concern I have is you have to tighten the clutch knob very hard when retrieving in or it will back off and free spin back out. Just have to wait and see if this becomes a problem in the future.



by:

Absolutely a great product I have used before. The trailer is a great company to deal with.

  • Is There an Extra Wiring Harness Available for the Dutton-Lainson TW4015?
    I spoke to Dutton-Lainson and there is replacement wiring for the StrongArm Electric Trailer Winch - Marine - 1,500 lbs # TW4015. The Wiring Harness for DC StrongArm Electric Winches # DL24151 will be a direct replacement, or addition in your case.

  • How to Power an Electric Winch on a Trailer Pulled By a 2017 Subaru Forester
    You do have a few options to get an electric winch, like the Dutton-Lainson StrongArm # TW4015, working, but the 4 Flat will not be able to do so alone. The first will be to add a battery to the trailer. This will usually be my suggestion, but as you do not have brakes on the trailer and it is for a boat trailer, it will not be the best way to go. What I suggest doing is upping your 4 Flat to a 5 Round, both on the trailer and vehicle. The Pollak 5-Pole # PK11502 for the vehicle side,...

  • What Is The Thread Pitch Of The Replacement Side Knob For The Dutton-Lanison StrongArm Winch?
    I contacted Dutton-Lanison, and they mentioned that the Replacement Side Knob for Dutton-Lainson StrongArm Electric Winch # DL94FR for the Dutton-Lainson TW4000 StrongArm Electric Winch # DL25200, and the Dutton-Lainson StrongArm Electric Trailer Winch - Marine # TW4015, has a thread pitch of 1/2-20.

  • Can Dutton Lainson TW4015 Electric Winch Be Powered From Vehicle's 7-way Trailer Connector
    You could use a 25' x 2" strap like part # DL24249. The maximum power draw of the Dutton-Lainson # TW4015 StrongArm winch is 40 amps, which would blow the fuse/circuit breaker on the 12-V feed to the 7-way of most vehicles, which is usually protected by a 30A breaker, and the winch could exceed that. The best practice would be to use a quick connect harness like part # DL24151 and wire the winch directly to the vehicle battery.

    The best option we have for your application is the Dutton-Lainson StrongArm Electric Trailer Winch # TW4015. This has a 1,500 lb capacity rating, a cable, free-spooling drum, and a remote.

  • Does StrongArm Winch Need Mounting Bracket

  • Does Dutton-Lainson Electric Winch # DL25200 Power Switch have to be Held to Power Load In
    The power switch on the Dutton-Lainson winch # DL25200 is a spring-loaded switch that must be held to power in the load. It was designed this way to reduce the chance of running the motor too long when under load by accidentally leaving the switch on. It is also a safety feature should your hand come off the switch. I recommend going with the version that has a remote, # TW4015. The remote cable for this winch is 10 feet long. If you need a longer remote cable I recommend the Bulldog winch...

  • Best Electric Boat Trailer Winch and How to Determine Capacity
    I would be happy to help you! When it comes to choosing an electric winch or any winch for a boat trailer, there are a few general rules we can use. The boat-size-to-winch capacity is generally 2 to 1. With good rollers and short winching distances, the ration can increase to 3 to 1 and with wooden bunks and long winching distances, you will want to reduce the capacity to 1 to 1. Since you have plastic sides instead of carpet you will probably be in the 2 to 1 range. I recommend the Dutton-Lainson...

There are so many different types of batteries now at wildly different prices that it is easy to get lost but you only need a basic battery.

    If the Dutton-Lainson Electrical Quick Connect # DL24086 for your Dutton-Lainson StrongArm Electric Trailer Winch # TW4015 gets wet when launching and loading your boat you should disconnect the circuits to protect them from damage in the water.

  • Electric Boat Winch Recommendation to Work with Lithium Ion Battery

  • Can Dutton-Lainson StrongArm Winch be Hooked to 12V Outlet in Vehicle
    Hey Shaun, Appreciate the purchase and I definitely understand wanting to be more efficient, but the Dutton-Lainson StrongArm Electric Trailer Winch # TW4015 should not be hooked up to the 12V outlet as the winch needs a direct connection to the battery. This is to protect the electronics and wiring on your vehicle as that outlet is not designed to pull the power a winch needs and could leads to all kinds of chaos.
