Video Transcript for Yates Rubber Boat Trailer Parts - Roller and Bunk Parts - YR410Y-4 Review

Today we're going to review part #yr410y-4. This is a Yates spool roller for boat trailers. This roller is constructed of thermal plastic rubber material. It is a non-marking, non-scratching material. This material is stronger and more durable than your traditional rubber roller. It is also softer and more pliant than the polyurethane rollers.

This roller will replace the standard spool roller on your boat trailer. Does help in the loading and unloading of the boat and it will support the keel of the boat as it sits on the trailer. This roller will also help absorb the road shock while the boats being towed. This product is made in the USA. We're going to do a couple of measurements on it.

The length of this roller is 4 inches. The diameter is 3 inches and this roller is designed to fit on a 4 inch wide bracket with a half inch diameter shaft. And that should do it for part #yr410y-4.

not only did i receive my 2 spool rollers in record time but they were perfect 785072

- YR410Y-4

Installed these on my boat trailer.. Did not use the boat for the remainder of the season so I can't comment on their rolling capabilities.. I am sure they will be fine.. 726613

Looks like they have been sitting in a box out in the sun. 679461

This Spool Roller is an off-yellow color. We store our products inside our warehouse, out of the sun.

Product arrived with no defects and undamaged. It fit perfectly on my 1/2" bolt, resulting in a nice smooth spin. Hopefully it holds up for many years. 665018

All the materials I received from E-Trailer were well made and easy to install. It was also easy to navigate the website to find exactly what I needed, and the prices were the best I could find anywhere. I highly recommend etrailer. Before and after pictures of my trailer are enclosed 652468

The old rubber roller on my boat frame split while we were loading the boat on the trailer after fishing. Because of my previous good experience with etrailer, I searched their website and found this 4 inch roller which fit perfectly. I especially like that it is made of a modern plasticized rubber which I expect will outlast the old rubber roller. It also doesn't mark up the hull like the old (black) rubber used to. This is an excellent product replacement for standard 4 inch boat rollers, and I will purchase it again if I have to replace any others. 551606

Perfect replacement for rubber rollers 449734

Though its been a year, they still look brand new. Much better than the standard rubber rollers. 417881

- YR410Y-4

I needed rollers for a non trailer use to remove my fiberglass boat from the water. I previously used black rubber rollers which failed after two years. The new rollers appear harder and have a plastic bearing surface. Everything works great when new. Let's see how they last over time. Shaft hole was larger than 1/2" specified but seem to roll ok. Ground transportation was slow, but I was not in a hurry. Price was half of what big box sporting stores wanted. 264946

Well, one of the rollers is failing, but the other four look like new. No idea why, they all share the same load, about 800 pounds from my 15 runabout.

I have an older Spartan trailer. Parts can be hard to find. Found what I was looking for at a fair price. Paid extra for quicker delivery. Received what I ordered by the promised delivery date... what more could you ask for... Would definitely use etrailer again and would recommend them. 225848

Ask the Experts about this Yates Rubber Boat Trailer Parts

  • Internal Surface of Yates Spool Roller for Boat Trailers YR410Y-4
    I went out to the warehouse to take a look at the Yates Spool Roller # YR410Y-4 referenced in your question. The inner portion/axle does indeed run completely through the roller, from one end to the other. The roller measures 4 inches long and 3 inches in diameter. I have also attached a short video review on this product so you can get a better look at is physical features.

  • Can a 3-1/2 Inch Spool Roller be Used in Place of a 4 Inch Spool Roller
    The short rollers will only be a problem if they present gaps in coverage or are otherwise not large enough for where they make contact with the boat. And if the play in them is too much, that could cause the boat to shift in transit. You can take up the space using washers. Ideally, you would want to replace the rollers with the right size like the 4 inch spool roller # YR410Y-4 that you have referenced.

  • Should a Bow Roller be Used in Place of a Spool Roller
    A bow roller like the part # YR450Y wouldn't be any more resistant to damage than a spool roller like the part # YR410Y-4 that is similar to it. It could be that your spool roller is mounted too high and too much of the boat's weight is resting on it instead of the bunks of the boat and that is why it is getting damaged.
