I purchased this product because my existing roller was completely shot. I have absolutely loved this new roller assembly so far, it has been a great addition to my boat trailer!



by:

This product worked as described and was advertised at a very reasonable price. The video on their web site was very helpful in description of this product. It was super easy to install and looks great on my trailer.



by:

Great product and great price. I also like the fact that it comes with grade 8 hardware.



by:

Direct replacement, fits like the origi nal.



by:

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.



by:

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.



by:

Exact fit!! Great, love it!



by:

Love it!



by:

Just as advertised



by:

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. A buyer has to compare this product's cost and then add shipping as opposed to others that include shipping in their price.



by:

My roller on my trailer was still functional, but ugly. I went searching on my “go to” place, Etrailer.com and found the exact new replacement roller. It fit perfectly and looks awesome again. Nice quality as well.



by:

etrailer was the only place I could find this part. Quality and fit were both excellent.



by:

The description was spot on, which made the fit perfect. Haven’t notice any new marks on my boat yet. Would give a five star, but haven’t had it long enough yet to give a higher rating. This is my second purchase from etrailer, and will continue to purchase from them.



by:

I've ordered several items from etrailer now and would highly recommend them. Quality products, great shipping, easy online shopping and awesome support.



by:

Good product, prompt delivery, fair prices, would use etrailer again for my boat needs. Scott



by:

Fit perfect. Easy to put on. Still looks great after a year



by:

Thank you to etrailer.com for having this product available and getting it to me quickly. Great selection, price and service.



by:

This product was as advertised and installation was easy. I now have a new roller to protect the bow of my boat.



by:

The roller fit with no modification and works perfectly. Excellent replacement bow roller.



by:

Easy, user friendly website. The tracking info had a personal feel: seeing pictures of employees who handled our order from beginning to end was a nice touch . Excellent customer service, excellent company.



by:

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.



by:

Perfect fit for my 2000 Shorelander Profile 2000 boat trailer.



by:

Best price I could find and the upgrade took minutes but now I don't have black marks all over my bow.



by:

Perfect replacement for the bow roller on my Marine Master trailer. High quality roller with correct hardware. Super easy install.



by:

Site was easy to navigate and place the order. Shipped quickly and product was just as explained. Looks great and look forward to no more black marks from the old roller....

  • Bow Rollers With Bell Ends For a 3-3/4" Inside Width Mounting Bracket
    The Yates Bow Bell # YR400Y I see you were looking at the 5-1/4" diameter is the outermost diameter of the roller. This particular part is designed to fit on the outside of the bow roller bracket. Here is a list of the bow roller assemblies we have with bell ends that will fit a 3-3/4" inside width 4" outer width mounting bracket. Black TPR # YR450BLK-400BLK Blue TPR # YR450B-400B Yellow TPR # YR450Y-400Y

  • Bracket For The Bow Roller Assembly YR450Y-400Y
    The CE Smith Bow Roller Bracket for Winch Stands # CE31005PG will work with The Bow Roller # YR450Y-400Y. The bracket accepts any 3 inch to 4 inch bow roller or Y-stop. The bracket is made out of 11-gauge pre-galvanized steel that can be painted to match your trailer. The bracket has a bolt-on installation but does not come with the included mounting hardware. I attached a review video link below.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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 shaft...

  • 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...

  • 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.

  • 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.

  • What is the Closest Bow Roller Assembly Available for a 3-1/2" Wide Bracket
    No, we do not have a bow roller assembly that fits a 3-1/2" wide bracket. The closest that we have are for 3" or 4" brackets. 3" - Bow Roller Assembly # YR300Y-325Y 4" - Bow Roller Assembly # YR450Y-400Y
