These guide-on posts make it easy to load your pontoon boat onto your trailer. They attach to the rear of your trailer and extend out of the water, providing a visual target to center the boat's pontoons around. Mounting hardware included.
Features:
Specs:
Note: Check with your state Department of Transportation for restrictions regarding maximum trailer width.
When your boat trailer has been backed down the ramp and is partially submerged, these 22" tall guideposts that are mounted at the rear corners of the frame will stick out of the water, giving you two highly visible targets to guide your boat between for loading. The galvanized steel support posts mount horizontally on top of or below your trailer's frame rail. Just slide the posts into the boat guide supports and secure the posts so that the distance between the bunks correctly matches the width of your boat.
Pre-Galvanized Steel
Pre-galvanized steel parts are stamped from a sheet of steel after it has already been galvanized. The edges of the pre-galvanized parts often lose their zinc coating during the stamping process. Because of the thinness of the coating less than 1 mm and the fact that the edges remain exposed, pre-galvanized parts can begin to oxidize and rust quickly, so its recommended that they be primed and painted.

These things work great. Putting pontoon on trailer during windy days was always an issue. With these guides the problem is solved
I attached these pontoon boat trailer guide ons yesterday. They made a huge difference when I trailed our 20' pontoon boat. They are more substantial than I expected and mounted easily in about 10 minutes with all included hardware.
E-trailer web site was very user friendly and they shipped immediately.
I received these post guides for my Yacht Club trailer to guide my 20 foot pontoon on to the trailer bunks. I installed them on Wednesday to the trailer about 2 inches from the inside of the pontoons. I did add some sections of hose over the threaded ends of the clamps to prevent any damage to the pontoons in the event that the boat would approach the trailer off center. My wife and I loaded the boat on the trailer this Thursday and it went on slick and easy as could be.
I have not used these yet and won’t be until spring as I live in MN. I will be installing them on my boat lift not on a trailer. I usually go out fishing alone. If there is any wind at all, even mild wind, it Is very difficult to keep the back part of the boat in the center of the lift while going to the front to turn the wheel to lift the boat up. I can hold the front of the boat in the center of the lift with one hand and turn the lifting wheel with the other hand. This should work well to keep the boat very close to exact center when coming in from fishing. I will adjust the Guide Ons so they are about 2” outside of the rear rim of the boat.
Purchased this item to use on my pontoon trailer when removing in the late fall. All hardware works as described...only issue are the pvc tubes that are provided: way too short. Backed the trailer down the loading ramp and the miniscule tubes disappeared under the water kind of negating the reason for buying this thing in the first place. Went to Lowes and bought a 6' length of pvc, cut it to the correct height to fit under the pontoon and all is good. Manufacturer: maybe have your ppl measure the undercarriage of a pontoon to get functional clearance on these pvc pieces? Just a thought.
The ordering was easy and quick. It arrived on schedule and it was easy to install. I did not use the product for a pontoon boat. I used it on my 22 foot off shore fishing boat trailer to act as a guide on the rear of the trailer when loading my boat. I did not use the tubing over the bracket. I installed rollers on the inside and mounted my trailer lights near the top of the brackets to keep them out of the water when loading and unloading the boat. It looks perfect and I know it will work well for my needs.
Product works great can put pontoon on trailer by myself no need to have friends hold ropes to guide on
The picture shown above has the bracket mounted backwards from the instructions in the package. The package instructions have the bracket facing inboard (not outboard as shown in your picture).

Hi Alexander, hopefully the instructions didnt cause too much trouble. The instructions are mainly a guide for attaching the guide-on post to the trailer frame. Whether the post is situated facing outboard or inboard is up to you, so you can mount it in whichever position best suits your trailer setup.
They haven't been installed yet but delivery was great
Not what I wanted, but it will work. Need a better description or picture with overall lengths of steel tube. Measurements need to be seen from inside and outside dimensions.
Just received the product looks like it will make loading my pontoon boat easier
Great product. I bought two sets. Shipment was extremely fastttttt. I glued the PVC cap on and ran a stainless steel self tapper on the inside of the PVC so they don't blow off when trailering unloaded even though Anna @etrailer said they SHOULD NOT...........I don't like the word SHOULD!!!

PERFECT !!!!!!!!!!!!!
the guides were lighter gauge than I imagined and a 25 ft. tritune boat is heavy enough that bends the guides when loading the boat in the wind.
good quality but for my application, too light.

Best addition I've made to my boat! Makes trailering the boat extremely easy when time to leave the water. My wife struggled to load the boat, but now does it with ease. Highly reccomend these guide ons.

A year later and this product still rocks!! Very awesome!
Easy to install and sturdy. Works great to help center up tritoon on the trailer.

Tritoon, eh? How do you like the tritoon in comparison to a pontoon? They look like they'd be super nice!
Just what I was looking for to aid our boat launching.
Easy to install.
Price is right.
Would like to see plastic closures for the open end of the frame.
DNR is all about weed transfer and small openings should be closed up.
It was always a hassle loading our tritoon without these guides, worked excellent the first time we loaded with them. They lined the toons up to the bunks on the trailer the first try!! I ordered these on a Wednesday and received on Friday.
After installing four (4), two forward and two aft on the trailer, they weren't capable of holding my tritoon inline with the trailer and bent over. I would not recommend this product for the use with a Tritoon.
The order came as described, and installation was very quick and easy, and I am extremely pleased with the product
These are a life saver for guiding the boat properly onto the pontoon guides. It was VERY difficult to do that before I bought these.
I ordered Two Sets for my Trailer the trailer is 24' long found that putting one set on the second cross member back, and one set on the third cross member from the back of the trailer. works fool proof for me. No accidental drive off. Very pleased with ths great product
I am very pleased with this product. These guides are really nice, well made, went on easy, and saved a ton of time. I used a slightly longer PVC pipe on the rear guides to help see them when the trailer was submerged. They're now 28" vs 22". Probably not necessary but I tend to overdo things. etrailer is now saved on my favorites for future needs.
The C E Smith post style guide-ons for my pontoon boats trailer were easy to install. My trailer has 5 3" C channel cross members. I installed the guide-ons on the 2nd an 4th cross members about 1 inch inside the pontoons.
Installation was simple.
Unbolts are a little long for my trailer frame but nothing my grinder can’t shorten.

Still a great product like the way the pontoon hits the guide and straightens itself out
