Video Transcript for Yates Boat Trailers Bow Roller Review

What's up everybody, it's AJ with Today we'll be checking out the Yates bow roller. So this is going to be a replacement part that goes right here on the front of your trailer. Let's say yours is worn down or it's not spinning like it's supposed to anymore because it's been out in the weather so long. It's an easy part that you can replace and get back up, running as new. Let's check it out.

Now what this is gonna do, is it's gonna go right here on your trailer and you can roll it, so that means when you're pulling your boat on there, and let's say the bow hits it, it's gonna roll up like that and it'll be just fine, it'll roll all the way. Acts as a stopper too, so as it hits this, it's better than it hitting the trailer and scratching up your boat. Also, when it's just sitting on there and you've got to tie it down, if your boat is to move and travel up and down, it's gonna hit this instead of the metal parts of your trailer, so that's, again, just gonna save your boat from getting all scratched up and damaged. It's made out of a thermal plasticized rubber. So it's gonna be a little more soft than regular polyurethane and has a little more of a structure than rubber does, so it's a nice in the middle of both of those.

I also wanna point out that the material it's made of isn't gonna leave marks on your boat. So some of the other ones, if it was just made rubber, and you we're to come up here, pull your boat up and hit it kind of hard, it might leave black marks here on the bottom of your boat. This isn't gonna happen with this one, there's not going to be any scraps or issues. Now I'll give you some measurements. It's going to be three inches and three quarters long, that's the width here.

And then it's also gonna have a diameter here where the hole where you gonna put the bolt in is going to be a half inch. So that way you can just get the right hardware to make sure it's gonna go through your trailer and your roller. Now you also can get these in a couple different colors, they also will come in blue and black. So if you don't want the yellow one that we we're installing today, there's two other options at might match your boat trailer a little bit better. It's really easy to install.

You just take this bolt out. Check out how we did it, Ready to install our new roller here, we're just going to set it into place. We're gonna use the existing hardware from the old one that we took out. Just slide it through the holes in the middle, mash it up on the other side. Now, something that would suggest is if you aren't getting ones with the bells on the side, and you see this the old one we took off. It did have those, so this bolt's a little longer than it should be so it's gonna stick out. You can get different sized hardware to run through that where there's not as much sticking on both sides, but this will still work like this. So we have the washer on this end, push there, and then we're gonna put a washer and nut on the other side. Just gonna get started by hand and I'll come back with tools and tighten it down. Got a ratchet and a wrench on here, just need to go ahead and tighten it down. So I went in, tighten it down, made sure the bolt head and nut here are tight, but this can still freely spend 'cause we're gonna need that when you go to put the bolt on. Overall, super easy to replace and get this part back up and running. and I liked this one because it's not gonna scuff up the boat either. So you don't have to worry about making any marks and now this rolls like it was supposed to again, it's gonna all work with that trailer and make it easier to get that boat up there. Well, I think that does it. Thanks for hanging out. I hope this helped..

Yates Bow Roller for Boat Trailers - TPR - 4" Long - 1/2" Shaft - Yellow - YR450Y

Replace the standard rubber bow roller on your boat trailer with this yellow thermoplastic rubber version from Yates. TPR material is stronger than rubber and softer than polyurethane, and it won't leave marks on your boat.


It says 4" long. It is not. 3-3/4" and that leaves too big a gap on both sides. the rubber one I had was the right size, this Yates roller is not.

This bow roller is 3.75 inches long to fit with a 4 inch wide bracket. I am having our product page updated so that it is clearer on the size. I checked and I do not have a wider 4 inch roller to offer.


Far superior product compared to what was on there (old 19 year-old rubber rollers). To do my ShoreLand'r trailer, I hooked up the trailer to my pickup, chocked the wheels, jacked up the front end of the boat while keeping the winch line hooked up, and unbolt the old roller. Then simply install the new roller, check your bolts, and your ready to hit the water. Thanks!


This is the easiest upgrade you'll ever make to you boat trailer! It takes all of 5 minutes to install. I bought this to replace the old (my boat is a 97 and I believe this was the original rubber roller) that was making black marks on the boat. No more marks with this roller and it was a perfect fit! Shipping was fast. Best price around. There is no reason to ever use a rubber roller again. I just wish I did it sooner.



We needed to purchase 5
rollers for our boat trailer but were unsure of a couple details. I called etrailer's help line, was connected with Greg S. We knew we wanted to try Yates TPR rollers. Greg was very helpful and patient with me on the phone.
Completed the order late in the day (about 3:00 pm). I asked if they would ship the following day and he assured me they would. Checked email just before supper and had an email from etrailer that our order had shipped same day. Had the rollers in two days.
Excellent service. Will use them again.

Ron M



Rollers are performing as expected and as advertised. Would use them again


Johnny Lightning delivery!!! Fit perfect. High quality


I use this as a hose roller and it works great.
Wish it was deeper grooved but since this is not what it's made for it still works fine.


Works well, does exactly what I wanted it to do.


IN the past the black rubber rollers did not last a year before getting a flat spot or two, making it hard for them to rotate. After one full year this roller shows no sign of wear, much less any flat spots.


Much better than the black rubber roller I originally had which would leave marks on the nose of my boat. I intend to replace all the rollers on my trailer with the ones made of this non-marking material - I'm so tired of scrubbing black tread marks off the hull.


This is an outstanding roller. Just had to get that out right away. My trailer had the factory black rubber rollers that had totally worn out and were about to fall off. I wanted something, if possible, that was more dense and much tougher than the rubber rollers. I have an aluminum V bottom boat and the aluminum V is very tough on the rollers. I came across this on eTrailer and the price was just a fraction of what the local marine supply wanted for trailer parts. Local markup is definitely quite shocking when you see eTrailer's prices! Bottom line, this is an outstanding roller. It's very tough, the v shape helps center my boat so it rides more level, and it just looks good too. I couldn't be more happy and will not go anywhere else for the parts I need.


I’ll start be giving a huge AWESOME JOB TO THE STAFF, for the great service. I ordered the Yates keel and bow rollers to replace all the old black rubber on a stainless steel Boston Whaler trailer that I built for a friend about 18 years ago. The local suppliers didn’t have everything I needed in one place. So I checked online and found and ordered keel rollers, end caps, bow roller with bell ends. Confirmed the order about 3-4 in the morning Hawaii time and learned the order was shipped less that five hours latter. And the box was sitting outside my door two days later. Damn that’s fast, especially to Hawaii. Being a first time buyer , that’s one hell of a first impression. With pricing and shipping can’t be beat. Very much appreciated.


Oh yeah, Im supposed to review the product too. Well, Yates TPR rollers good product, good price and exceptional service!!!

Mahalo and God Bless,

George D.


Good product-good description online. The new product replaced an old damaged boat part. Easy to order-shipped timely and easy to track the new product from initial order to delivery. I always enjoy dealing with etrailer on ordering products--really helps to have such good support services from etrailer. Thanks


Nothing too technical about the part itself. A simple swap out of the old parts. Matched the dimensions of the OEM parts so the installation went smoothly. Deliver from etrailer was excellent and prompt. Will definitely continue doing business with etrailer! The best online vendor for providing installation videos and answering technical questions. Keep up the good work!


A solid bumper bumper?, not honeycombed like the competition. Some idiot had put a 3" bumper on a 4" fork on my trailer before I bought it. It beat up the front of the boat over time. Since I just repainted the boat I felt I needed to get the bumper back to what it was designed for. This solved the problem. Hardest part was spreading the fork back to the 4" width.


YR45Y Seems to be a good quality product material wise. The bolt shaft hole was off centered 5/16" (I measured) which may cause flatspotting from the boat bow over time if it doesn't roll true when impacted. I also ordered the beveled end cap rollers as well that seem just fine. Fully assembled on the trailer you can see the offset in alignment in the center roller vs. The endcaps.


Very good product....still going strong


Our boat trailer is old, and we were surprised to find parts at such a great price.

Susan W.


wonderful, would purchase from Yates again, if I needed anything


Excellent durability still looks like n ew


Jack and roller arrived on time and no visible damage on either.


great service at lowest price I could find on the internet. Arrived early and fit like a glove...who could ask for more.



No problems, good product.


I am always pleased and satisfied with anything I have ordered from Etrailer. Best selection of products. Best product views, photos and multiple angle photos of products makes it easy to see the true scope of the products. Best descriptions of products. Complete listed dimensions of products makes it easy to know the exact size of the item.


Great product and hard to find something that was an exact fit to replace the original trailer component. It fits a 4 inch bracket, but the piece actually measures about 3-3/4 inch wide. Does not leave marks on my hull either.


This works great. I bought the end caps and the whole thing gives me a much larger target to hit when pulling my sailboat onto the trailer.


I purchased a Bow Roller for my boat trailer. It was a direct replacement of my OEM roller at about a third of the cost. Now after I install it I can again secure my boat snuggly against the trailer. For me it was the Best Value.


Bought some rollers to make a boat lift. Product was exactly what I wanted. Delivery was better than I expected. You helped to make the project go smoothly and I thank you!

Jeff S.


Really well. 100 improvement over old boat lift

  • Aluminum Hull Boat Destroyed Keel Roller on Boat Trailer
    Most rollers for boat trailers are made from rubber or thermal-plasticized rubber (# YR450Y is the latter). These materials are used because they are soft enough to not damage the hull of the boat but tough enough to withstand normal use in both salt water and marine applications. If the keel on the boat dug into the roller and destroyed it that way then it could be that you need additional rollers to support more of the weight. Or it could be that the roller being used wasn't quite the...

  • Bow Roller Recommendation for a Trailer with a 3-5/8 Inch Wide Bracket
    You would want to go with the 3 inch Yates Bow Roller for Boat Trailers # YR300Y. This would fit well on your bracket that is 3-5/8 inches with only a little over a 1/4 of an inch of gap on either side of the roller. A 4 inch roller would be too wide and wouldn't fit.

  • How To Stop Scuffs On Hull Of Boat When Using CE Smith Multi Sport Boat and Kayak Trailer
    If you replace the bow roller with one that is non-marring then that should fix any issues with scuffs on the hull of the boat. For this, I recommend the Yates Bow Roller for Boat Trailers part # YR450Y for 4" wide or part # YR300Y for 3" wide.

  • Recommendation for Replacement Bow Stop Roller Measuring 4 Inches with 1/2 Inch Hole
    Hey Craig, thanks for your recent order with We really appreciate your business. I have a couple different options that would work for you. Yates offers the thermoplastic rubber bow roller in yellow, # YR450Y, and blue, # YR450B. The thermoplastic rubber material is stronger and softer than the standard polyurethane rollers and it won't leave marks on your boat. These rollers measure 3-3/4 inches long and are made to be used in 4 inch wide brackets with 1/2 inch diameter...

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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...

  • Recommended Bow Roller for Boat Trailer
    Based on your attached image, but double check your measurements before ordering, I suggest the CE Smith Bow Roller for Boat Trailers, # CE29542. This 3" PVC roller is of non-marring material, so it won't leave scuffs or marks on your boat. It is stronger and longer lasting than rubber and works in fresh water and in saltwater. If you check the width and discover a 4" (actual length 3-3/4") would be best, then I suggest the Yates Bow Roller for Boat Trailers, # YR450Y. This yellow...

  • 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.

  • Replacement Bow Roller Bracket, Shaft and Roller
    We don't have any bow rollers that will fit a roller larger than 1/2 inch in diameter so the best recommendation I could make would be to replace your current setup with something like the part # CE31005PG for a bracket, part # CE10700A for a new roller shaft, and then part # YR300Y for a roller.
