Video Transcript for What to Know About the Yates Bow Roller for Boat Trailers

What's up everybody, it's AJ with etrailer.com. 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..

Excellent



by:

My order came quickly and everything I ordered was in the same box. I installed everything yesterday. Etrailer was easy to do business with I will be back



by:

Product was exactly as described. The exact measurements of the product where very helpful, in fact that is why I bought from etrailer. Other websites did not provide as detailed information.



by:

The part came quickly, easy to install, has proved to be very sturdy, and does not mark up my sailboat hull.



by:

A great bow roller at an excellent price.In fact , I need 2 more 4 inch keel rollers ( blue ) that I hope they can sell me. This is a great place to get all of your trailer needs !!!



by:

I plow plastic pipe into the ground for livestock water. I bought these puppies to be pipe guide rollers on my cat dozer. They will keep the pipe in alignment as it comes off the spool and guide it into the ripper boot. Each spool has 2,000 ft in it. The first job is six miles long. Should work like a champ!



by:

Exactly as described, excellent customer service.

Thanks for the follow-up,So far, so good! Im still very happy with the products and more than satisfied with the customer service your company provides.Have a great summer!



by:

Perfect replacement,,, better than the original. Care was taken when packaging and shipping was very timely



by:

With this roller having a drop/lip about 1-1/8" in from the edge on both sides, our boat will rub on both sides as it comes up on the roller. Do you have a roller that is a smooth transition from the edges to the center? The 4" fits, but not the drop/lip coming to the center of the roller from each side. We would like to return it and get a different one if you have what we are looking for.
Thank you for your time

Part # YR4174-4 would be a better fit. It is still four inches long but doesnt have any differing grooves. Its all one smooth angle. I can have our customer service team reach out.



by:

The Bow roller and tail light converter arrived promptly and in exactly as described. The tail light converter is a blessing. My 1998 Toyota 4Runner now throws the correct signals to my boat trailer. Yeehaw!



by:

This was a great replacement for my old worn roller that was on my trailer and it got here quick also.

holding up great still looks brand new



by:

Great product and a great price. Shipping was fast. Upgrading my boat trailer and the existing bow stop was beat up from power loading. Now with parts from etrailer it is looking like new again.



by:

I was very impressed with the great service, excellent products, and end results after assembling my boat trailer with the parts ordered from Etrailer. Shipping was fast. Very reasonable prices. Will definitely order thru this company again and have already referred friends of mine to have them take a look at your site.



by:

Came fast, was what I ordered, considering how fast, I would have preferred slower shipping at less expense.

Still just fine



by:

The roller worked perfectly for the trailer I was redoing. I also bought a couple of other parts that I needed they have great products, quick shipping and excellent customer service. Will keep buying all of my trailer parts from here



by:

I keep my boatvin a heated shop here on our farm. So it's not exactly exposed to the elements. But since installing this rubber bow roller on my trailer i have pulled my boat more than 5 times and the rubber bow roller is showing signs of bad wear and for some reason a chunk of rubber has fallen off. We are heading out for a 4 day fishing trip soon and I just hope it lasts long enough to get me back home. Not exactly happy with it.



by:

I am a trailer sailor and always looking for ways to make the task of raising the mast easier. I am in the middle of creating a roller stabilizer A frame to keep my 30' mast from wandering to either side while raising it. This roller is part of my new system and I expect it to keep the mast centered upon lifting. However, it is still snowing here in The Rockies so the actual test is going to have to wait a while longer.

After some revisions to the yoke that holds the roller, it seems to handle the load of raising the mast very well. Overall, a good item for my needs.



by:

as you can see, I still have some parts to replace. But I ordered these parts at the beginning of this week. Used free shipping. Delivered Saturday, done Saturday afternoon. So easy. Looking forward to finishing this trailer. Will use etrailer again

  • Choosing A Replacement Bow Roller
    When choosing a replacement bow roller for your boat trailer, you want to measure the width and diameter of your current bow roller.

The Yates Bow Roller # YR450B is a great replacement for a bow roller that is 3-3/4 long with a 3 inch diameter. The # YR450B roller fits on a 4 inch wide bracket with a 1/2 inch diameter shaft.
