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

Ask the Experts about this Yates Rubber Boat Trailer Parts

  • 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...

  • 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 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.

  • Size of the Ends of the Bow Roller Assembly w/ Bells # YR450Y-400Y
    One the Bow Roller Assembly w/ Bells # YR450Y-400Y the diameter is 5-1/4 inches at the widest point and 3-1/2 inch where it attaches to the shaft. The shaft diameter it is designed is 1/2 inch.

  • 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 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.

  • Can Y-Shaped Bow Stop Be Replaced with Bow Roller On Boat Trailer
    If you are referring to a bow stop such as the Yates Y-Style Bow Stop for Boat Trailers part # YR7Y44-4 then yes you can replace this with a bow roller such as the Bow Roller Assembly part # YR450Y-400Y which won't mark the boat. This can then be used with the CE Smith Bow Roller Bracket for Winch Stands part # CE31005PG or you can match one to fit the bracket you have now from the list below.

  • 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...
