Video Transcript for Yates Rubber Boat Trailer Parts - Bow Guard - YRJONBLOCK Review

Today we are going to review part number YRJONBLOCK. This is the Yates flat bow stop for boat trailers. This stop will replace the worn-out bow stop on your boat trailer. It is constructed off a heavy duty rubber material. This part is made in the USA. This stop will keep your boats bow in place when its loaded on your trailer.

The flat shape on this stop is designed for you to use with swift John boat inaudible. The stop will prevent the boat from hitting the trailer wench during loading and it provides a soft spot for the bow to bump up against the front of the trailer. I'll do a few measurements on this. We'll measure the base. The base on this is 2 and 7/8 inches wide and 3 inches tall.

Then we'll measure the span which will measure 5 and 3/8 inches. This stop is designed to fit on a bracket with a 1/2 inch diameter shaft. And that should do it for part number YRJONBLOCK.

Delivery was awesome; ordered and arrived two days later. Since my 16' aluminum Starcraft has a "flattened" upper bow from where a previous owner tightened the winch with stop against hull prior to pulling boat/trailer out of deep launch; this "jonblock" with flat surface was just what I needed. thanks.


Comments
As a follow up, the rubber jonblock on front of boat trailer continues to work just fine a year after purchase. Totally satisfied with this replacement of original trailer boat stop pad.

Great product at a great price. My problem was, with the roller on the front of my trailer and all the weight of the motor, trolling motor, and battery on the back of my boat, when I would travel down the road and hit bumps the front of my boat would jump up on top of the roller and then the winch strap would be loose and allow the front of my boat to slide back and forth. It fit very well where the original 3" roller was and even though I haven't tried traveling with the block in place, at least I can pull up on the front of my boat without it jumping over the block. I expect it will work exactly like I want it to.

Continental JB1612 Trailer and a Tracker 1542 Jon Boat. I have no idea why these don't come as standard. etrailer had far and away the best deal. Most places wanted some ridiculous price and/or an exorbitant shipping fee. Why I keep coming back to etrailer. Less than five minutes to switch out.

Great fit for my jon boat. Trailer had been fitted with a roller bow stop, which did not fit the jon boat whatsoever. The jon block fit perfectly on the trailer and mated up flush and secure with the boat.

5 stars all the way. I just installed my bow stop today on my boat trailer and it is awesome. Everyone that has a flat bottom boat on a trailer needs one of these. Thanks etrailer just what I needed. I am sending before and after pictures, so you can see how great it works. Thanks again

Obviously pretty simple, straight forward product, but nearly impossible to find at any local retailer in Houston area. Was glad to find here on etrailer's site and at a very reasonable price. Bought two for my Shoalwater trailer, perfect for squared bow as the photo shows. Excellent customer service on etrailer's part! Will definitely use again and recommend to friends.

Fast shipping and even faster installation. This took about 3 minutes to install and it fits perfectly. Here are some before and after pictures. I can't tell when I post this whether the before picture is first or second. Buy with confidence.

Still working great. The old hard bumper was dinging up my jon boat, but the rubber one from etrailer works great.

These were just what I was looking for They should come standard on every trailer that has a flat bottom boat

Was perfect for my jon boat. Had to make a new winch-stand w/ bow stop and it holds the bow perfect. And for around $15 +shipping it was the best price I found.

A must have for jon boat trailers. I purchased a new trailer and it came with a v-hull roller. My boat was getting wear marks from the tiny bit of surface space actually touching the bow. No matter how tight the winch was, the bow would still move side to side going down the road. This was taking the paint off and creating shiny spots. Thanks to this proper jon boat bow stop, my boat is secure for travel with no more bow wear.

Quick receive on this item. It bolted right on and is an improvement for a flat front Jon boat. I live on a river and have to speed onto the trailer and needed this bumper to spread the impact area on the bow. Not that it hits that hard, but you never know.



- YRJONBLOCK
by:

Though the YRJONBLOCK served its purpose it left a black stain on the hull of the fiberglass boat which is difficult to remove.

by:

Well made of strong durable material. Perfect product for flat bows on skiffs or Jon boats etc. Should be standard from the factory on trailers intended for them.

Holds the boat in place and doesn't mess up the finish

Bow stop. My Boston Whaler '13 Sport is not a vee-hull and it always bothered me that the bow-stop was this whimpy roller. As I was ordering parts to convert the trailer from rollers to bunks, I came across this heavy-duty bow block. I fit where the old roller was and what a huge difference and confidence booster to drive the boat on the trailer up against this beefy stop versus that whimpy roller. Thanks etailer.com for having these unique parts to make my boating experience all the more delightful

Seems like a good solid block and thats what I've been looking for a while. Never thought about looking at etrailer till I got an email for something else and found this also. Will have to do some rework to make it fit, but thats with most of my projects.I will send pics when I install it.


Comments
Been working great and was easy to adapt to fit where old roller was.

Provided a nice flat bumper for the front of the raft. This would work equally as well on a flat node jon boat.

Product described exactly as advertised. My bow hook actually “bumps” up to the block every time the boat is loaded. After one year of heavy use it is holding up better than I had expected. I’m a tournament angler and I take my boat out multiple times a month and transport it over long distances. This product has definitely been worth the purchase. My wife says if anything can be broken I will be the one to break it and so far this product has survived me and the abuse I’ve put it through.
