Today we're going to review part #yr3143-4. This is a Yates bow roller for boat trailers. This roller is constructed of a heavy duty rubber compound. It is made in the USA. This roller will replace the worn out bow roller on your boat trailer it does help in loading and unloading of the boat and it does support the front of the boat as it sits on the trailer. It also helps to absorb the road shock while the boat is being towed.

I'm going to do a few measurements on this. The length of this roller is 3 inches. The diameter is also 3 inches and this roller is designed to fit on a 3 inch wide bracket that will use a half inch diameter shaft. And that should do it for part #yr3143-4.

Preferred purchasing this item for my Shore Lander boat trailer, simply because of the ease of locating this item. This roller fits perfectly and was installed in a matter of minutes. Your delivery was faster then I expected.


Just what I ordered, just what I needed and just what I expected. Thanks and God bless.


Good service & good price


Exactly the roller I needed. Very happy with the quality!


Just what I needed to replace my rotten and broken bow roller on my boat trailer.


As always, I was able to find exactly what I required from, and in a very timely fashion, at a fair price. is a very upfront, honest, and conscientious dealer of some of the best "parts" on the market. I put my faith in them and their products each time I need something for my cars, boats, or trailers. Thank you

Product exactly what was needed.


The roller worked well and is of high q uality.


Part failed after 18 months even with boat/trailer being garage kept. OEM lasted 22 years.


Everything worked great. Thanks


Was as described

Had problem


Item arrived quickly and was easy to swap out.


I am very happy with Etrailer. This is my 3rd order in the past 4 years and all parts have to do with a early 70s shoreline boat trailer which carries a 1975 Seacraft Safari. The personnel are very helpful and shipping excellent. Very pleased with the tires and wheels I got in 2011. I will be finishing up installing the parts I got this year in the near future when I pull my boat. I will let you know if I have any issues.


Great price.durable shipping.i couldnt ask for better service.they also include tracking info so you feel at ease where your item is.very well done.thanks steve.h



Its doing great


Fit perfectly to replace the 3" Bow Roller that was deteriorating on my trailer.


etrailer is always an excellent resource for not only "advise" on their
products likes, but orders, and shipments arrive on time.
Their techs and customer service specialists are very knowledge, and if they
don't carry the product you need they won't sell it to you, they'll refer you to
another and integrity... They also followup on your satisfactory, in which many Companies ignore.

Thank you again


Just what I expected, just as described, just not like other companies online orders.

Perfect replacement for my 1950 trailer that had been made using washing machine rollers!

Nice working with caring people too.
I thought my order may have gone missing from my doorstep and called customer service to see what could be done. I was assured it would be taken cared of, then I found it had been delivered to the wrong address down the street.


What's to say? Good, solid, black rubber bow roller. Looks like their picture. Takes a 1/2" bolt or pin.

Chad P.


No problems. Still like new!


I bought two 3" and two 4" long rollers for a project and they worked well. You can't beat the price and etrailer ships fast. Good quality and no complaints.


I needed to replace the rollers on my jet ski trailer, but I had to replace them with rubber ones as the ones on my trailer were hard plastic and were rubbing away the finish on my ski. I am in Australia and was not able to find these in rubber anywhere at a reasonable price til I cam across etrailer. I received them today after sending them via my parcel forwarding company and I am very happy with what I got.


just what I wanted at half the price of others. they look like a good sold rubber material. have already installed and worked great.

Robert L.


great never even had a mark on it after a full season in the slip


Perfect fit and VERY easy to install on my Bass Tracker Pro Team 185 trailer tongue.



Still works perfectly!!


Good product, easy to exchange.


My little boat trailer needed some rollers and these fit on the 3" center rail perfectly. A few brackets and bolts and I'm ready to go fishing!


Great quality product for my boat trailer. 3 inch heavy rubber bow roller, perfect fit, and at an amazing price. Super fast service and delivery of my order. Very very satisfied with, I will use them for all my future parts needs.

  • How to Determine the Correct Bow Roller Needed For a 1999 Tidewater Boat Trailer
    To select the correct Bow Roller or Bow Guard, see links, for your Tidewater boat trailer, you will need to measure to determine the proper size. The width of the roller and diameter of the shaft that the roller installs on will be needed. Most boats that use a roller use the 3 inch Rubber Bow Roller, # YR3143-4, that you referenced, at the point closest to the trailer winch. This roller accepts a 1/2 inch diameter shaft.

  • Replacement Option for 3-1/2" Rubber Bow Roller
    The closest thing we have to a 3-1/2" long bow roller is the # YR450BLK. This is 3-3/4" long x 3-1/4" diameter and made of thermal-plasticized rubber. If you don't want the thermal-plasticized rubber we have the # YR4174-4 which measures 3-7/8" long x 3-1/2" diameter. Both of these are made for a 4" wide bracket with a 1/2" diameter shaft.

  • Shaft Recommendation for a 3 Inch Bow Roller for Boat Trailers # YR3143-4
    The 3 inch bow roller # YR3143-4 takes a 1/2 inch diameter shaft such as # CE10700A. The Pal nuts are included. The length of this shaft is 5-1/4 inches long so you may need to trim it down a little. The cut will need to be straight and smooth so the Pal nuts will still fit on the ends. If a bracket is needed as well we have numerous options. I have included a link to them for you.

  • Availability of 3-Inch Bow Roller for Boat Trailer
    We do offer 3-inch bow rollers and all can be seen on the linked page. These are offered in various materials including basic black rubber like # YR3143-4 and non-marking thermoplastic compounds like part # YR300B. All fit on a 1/2-inch shaft like the one included in CE Smith Keel Roller Assembly # CE32003G.

  • Parts Found In Pictures for CE Smith Bow Roller Bracket # CE31005PG
    The Fulton Single Speed Winch # F142306 appears to be the closest winch that we have to the one in the picture with the CE Smith Bow Roller Bracket for Winch Stands # CE31005PG. It has a similar mount and frame connection with the crank handle and switch in similar positions. I cannot tell you exactly what winch was used for this photo as it is a manufacturer image and likely the winch may no longer be in production. This winch has 1,800lb capacity and includes a 20' strap with 9" handle....

  • Bow Roller Recommendation to Fit 4 inch Roller that is Too Long
    Looks like you have the part # YR450BLK-400BLK installed and are needing the next size down which happens to be the part # YR300BLK-325BLK. This fits the same 1/2 inch diameter shaft but is 1 inch shorter than what you have. Your bell ends being deformed would not be a good sign.

  • Replacement Keel Rollers for 1959 OB-70A Boat Trailer
    Thanks for the pictures! I have a couple of options for you to replace the keel rollers on your 1959 OB-70A Tee Nee trailer. The Yates Keel Roller for Boat Trailers item # YR8244-105EC are 8" long and work with a 5/8" Shaft. If you are able to reuse your current bolts or replace them you will also need the Roller Shaft with Pal Nuts for Boat Trailer Rollers item # CE10725A. If you are unable to reuse your current mounting hardware or find similar bolts we have the CE Smith Deep V Keel...

  • Replacement Keel Roller Brackets for a Tee Nee Boat Trailer with 3 Inch Rollers
    The 3 inch rubber bow roller, # YR3143-4, that you referenced is typically used at the front of the boat near the winch. The rollers that are usually used in the middle and rear are keel rollers. Often times, the v shape of the 3 inch bow roller is too deep for the middle or rear end of a boat hull. I did some research on your Tee Nee trailer and it looks like there are a few different styles that will affect the type of brackets that you will use. If you have frame rails that run perpendicular...

  • All Parts Needed To Add A Winch To A Kayak Trailer
    I included a winch that will be very comparable to what comes on the CE Smith Multi Sport Plus Boat and Kayak Trailer # CE48870, but we do not have that exact model. I should also mention that there is no hardware included in this list, but everything else is.
