Video Transcript for Yates Rubber Boat Trailer Parts - Roller and Bunk Parts - YR300B-325B Review

Male: Today, we're going to be taking a look at a bow roller assembling. This bow roller assembly replaces the bow roller, end bells, shaft, and hardware on your boat trailer. Really helps ease loading and unloading of the boat. It's going to support the front end of the boat, as it sits on the trailer. It's going to help to absorb road shock, while the boat is being towed. The end bells are going to insure that your boat doesn't scrape along bolts or roller brackets.

The unit's constructed of a thermoplasticized rubber. That's TPR construction. It's s non-marking, non-scratching material that's stronger and more durable than traditional rubber. It's also more pliant. It's softer, more pliant than polyurethane.

It's going to be blue in color. All the hardware that it comes with is going to have a protective zinc finish on it, to resist rust and corrosion. The product's made right here in The USA. This is designed to be used with a three inch wide bracket. The bracket would install in-between the end bell and the roller on each side.

Brackets are sold separately. If we take a measurement of just the bolt or the center shaft, that's going to be five inches long, from the bottom of the bolt head, to the end of the threaded portion. Now, when it comes to the hardware, you're going to get the center shaft or bolt. You're going to get two flat washers, one for each side. You're going to get a nylon locknut. Taking a measurement of the roller length, just measuring that center piece there.

That's going to be about three inches long. The roller itself is going to have a diameter, at the widest point, of about three inches. That's on the ends. The end bell, at the widest point, that's going to give us a measurement of about four and a half inches. Then, the diameter at the attachment point, is about three and one eighth of an inch. The overall length, without the roller bracket installed, that's going to measure right around five and a half inches long. That's going to do it for today's look at the bow roller assembly.

As I have just received my item today I haven’t been able to put it on my boat trailer yet. It may be weeks from now but it appears to be just what I need. I like the material of the product it seems very well made. Ordering and delivery were both excellent. I have ordered items before and was very satisfied.

Well that is a bummer. May I ask why you were not able to use it?


by:

Very fast response to my order. Haven't installed the roller on my boat yet but I am certain that it will be an improvement over what I currently have.



by:

Fits good. Hull of semi V boat. Let you know in a few weeks how it does at the ramp.



by:

The plastic material did not hold up to heavy bow weight from 2002 Air Natique trailer config. After about 3-trailer loads, the inner wheel tore through and I ended up replacing with solid v-guide. Original roller was rubber but left black marks on white gel coat.



by:

Nobody else had these good looking blue rollers for my trailer...except etrailer.com. The bow roller was easy to install in about 5-10 minutes of time. The etrailer.com customer service is excellent!



by:

owned it for a year and this is exactly what I needed. I do believe I used stainless hardware instead of what was provided in the package



by:

  • How To Replace a Knot Autoflex Winch and Bow Roller Assembly On a Boat Trailer
    I do have a solution for you but we don't offer any integrated winch and bow roller setups like the Knot Autoflex. Therefore, you'd have to purchase a winch stand assembly like the CE Smith Winch Stand part # CE31013G which bolts onto the tongue and allows you to mount a winch like the Fulton F2 Fully Enclosed Trailer Winch part # FW20000301 and bow roller like the Bow Roller Assembly part # YR300B-325B when using the CE Smith Bow Roller Bracket for Winch Stands part # CE31005PG.

  • Non Marking Bow Roller for River Boat
    I like the non-marking rollers like the 4 inch bow roller part # TR450B-400B which fits a 1/2 inch shaft or the # YR300B-325B which is 3 inch wide and fits a 1/2 inch shaft. These two are the standard sizes commonly found so I'd measure what you have and go with the correct size.

    We don't carry the Knot Autoflex couplers, but we do have a solution that could work for you.
