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.

Perfect bow stop for a jon boat.




by:

Exactly as described and measurements were spot on. I used the Yates flat bow stop for my skiff driftboat trailer and the bow stop works as expected.




by:

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.




by:

I was thoroughly pleased with the Yates Flat Bow Stop. The stop fit perfectly in the bracket and we were able to adjust the stop to fit the bow of the boat perfectly. There was no gap at all between the boat and stop. I have had other stops before that did not fit as securely. We are really happy with the Yates stop.................We installed this on my brother-in-law's trailer and I didn't get any pics. If I get some pics, I will update the review.




by:

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




by:

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.

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.

The block worked very well thank you




by:

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.

Product arrived on time and serves the purpose of bow stop for flat bowed jon boat.




by:

Perfect. Just what I needed for the ole Jon boat.


Comments
Still going strong after a year.

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.




by:

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.




by:

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.




by:

Bumper arrived in a timely and good condition manner. The bumper is perfect , like they advertised. Mounts easy and my flat bottom is secured and protected. Gret product.




by:

I think this is going to work perfectly for my jon boat trailer. The rubber came in with some edges not trimmed properly,but I should be able to finish trimming the edges with a sharp knife. That is the only reason I didn't give it 5 stars. I also wish it was slightly softer rubber, but this maybe to prolong life. I was very pleased with etrailer's process from the beginning to end. Far better than some other retailers I've dealt with.




by:

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.


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

by:

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.




by:

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.




by:

This is what I was looking for, worded Great.




by:

Received it today as expected and it is just what I was looking for. Very happy!




by:

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




by:

Very fast shipping and the product was exactly as described




by:

Item arrived fast and on time. Exactly what I needed.




by:

Fast shipping and product works great on my 12 ft Skiff
