Video Transcript for Yates Rubber Boat Trailer Parts - Roller and Bunk Parts - YR450Y-400Y Review

Today we are going to be taking a look at a Bow Roller Assembly, this assembly replaces the bow roller in bell's shaft and hardware on your boat trailer. It's going to ease loading and unloading of your boat, and it's going to support the front of the boat as it sits on the trailer. It really helps when it comes to absorbing road shock while the boat is being towed. The end bell's insure that your boat does not scrape along bolts or roller brackets. The unit's made from a thermal plasticized rubber TPR construction, it's a non-marking, non-scratching material. It is stronger and more durable then traditional rubber, it's softer and more pliant then polyurethane. It's going to be yellow in color all the hardware that it comes with is going to feature a zinc finish, which is going to do a great job at resisting rust and corrosion.

It's made right here in the USA. This is designed to accept a 4 inch wide bracket, to get the bracket installed you would simply install one component at a time. You place the bracket on each side of the roller, then you would feed your hardware through each individual piece, piecing it all together so that the center shaft is what holds everything together. Bracket's not included, but again it is designed to work with a 4 inch wide bracket. That shaft or bolt is going to measure 6 inches long from the bottom of the bolt head to the end of the threaded portion, that's going to give of a diameter of 1/2 inch. When it comes to the dimensions of the roller, that's just this center piece here, that's going to give us a length measurement of around 3 3/4 inch long.

The diameter of the roller at the end, at the widest point, it's going to be about 3 1/4 of an inch in diameter. The end bell diameter at the widest point, that's going to be 5 1/4 of an inch, and then at the attachment point, which would be this point right here, is about 3 1/2 inches in diameter. The overall length of the unit, measuring edge to edge is going to be about 7 1/4 of an inch. Please keep in mind that's without the roller bracket installed. That's going to do it for today's look at the Bow Roller Assembly.

etrailer.com had everything I needed to replace critical parts for my 34ft. cruiser boat trailer. Reasonable prices and Wow SUPER FAST shipping!! I ordered YATES keel pads, keel rollers, bow rollers, roller end caps, pal nuts, and galvanized square U-bolts. All items were well packaged in one box. It's my second order from etrailer.com, very easy to navigate their inventory. One stop shopping. Absolutely will buy form etrailer again. 595034

This is a replacement on our boat trailer. Several months ago, I replaced the original that was getting aged, and the rubber was not as pliable as it used to be. After a few uses your roller I installed back in April, was ripped completely off one side while putting the boat back on the trailer. Something that has never happened before. This is the second one from eTariler, in a few months. This weekend the boat did not load as it used to. It was about to slide off the new set of rollers. I think this may have been made for smaller or lighter boats. It is much softer, or more pliable rubber than the original. I may have to find another, or return to the old original to the boat trailer. 540678

Exactly what I was looking for: good product, ease to order, price much lower than the Marine Store, delivered to my doorstep. However, try and get your shipping costs lowered.

This bow roller looks to be a much better alternative to the previous hard polyurethane roller that scarred my boat bow. It is much softer and rolls easier. 357841

Ask the Experts about this Yates Rubber Boat Trailer Parts
Do you have a question about this Boat Trailer Part?


  • How to Prevent Metal Bow Roller Brackets from Contacting the Boat
  • Almost all bow roller assemblies have an industry standard hardness of 85a durometers. I was able to call my contact at Yates to confirm this. I do have a solution for you but we do not have any bow rollers with a hardness rating greater than 85a durometers at this time. However, I believe the problem you are experiencing can be eliminated using a wider roller as this would in turn dissipate the weight more evenly to minimize contact with the metal brackets. I recommend using the Bow...

  • Solution for a 5 inch Bow Roller Assembly
  • I have a 5 inch roller, but the largest Bow Roller Assembly that we offer is a 4 inch, like part # YR450Y-400Y. The CE Smith Deep V Keel Roller Assembly # CE10401G is 5 inches and will accomplish the same task that a bow roller will. The only difference that you will need to consider is that the shank diameter for the 4 inch bow rollers is 1/2 inch while the keel rollers use 5/8 inch diameter shafts. You can take your old assembly off and mount this assembly if the 5/8 inch diameter...

  • Replacing Bow Strap and Winch Mount on on Older Shoreline Sailboat Trailer
  • That's a really interesting setup. We aren't really going to be able to help much if you want to use that winch mount in it's current configuration. If you could instead mount the winch like in the picture I attached you could then go with a different bow roller possibly. You'd be able to use the bow roller part # YR450Y-400Y you mentioned as well as the bracket part # CE31005PG.

  • Bow Roller Assembly w/ Bells # YR450Y-400Y Center Roller Width
  • The width of the roller on the Bow Roller Assembly w/ Bells # YR450Y-400Y that is between the center roller bells measures 3-1/2 inches. This is a super popular size so I would be surprised if this didn't fit your Shorlandr trailer but I'd measure first to verify.

  • Replacement Bow Roller for 2001 Magic Tilt Signature Series Boat Trailer
  • Boat trailer makers do not keep track of specific smaller parts like rollers but based on the photos of the 2001 Magic Tilt Signature Series trailer that I reviewed it looks like the Yates Bow Roller Assembly # YR450Y-400Y is indeed the correct replacement part. You can just compare dimensions to make sure. This roller fits on a 1/2-inch shaft and has an overall length of 6-inches. Please also refer to the linked review video.

  • Bow Roller Recommendation Near 4 inches in Width
  • For bow rollers we have 4 inch wide rollers like the part # YR450Y-400Y which would have an overall width of 3-3/4 inches and a diameter of 5-1/4 inches at it's widest point. Sounds like this would be your best option.
