Drotto Bunk Trailer Install

Video of the Drotto Bunk Trailer Install .

In this Drotto Bunk Trailer Install video we demonstrate how to install the Drotto boat latch on a bunk trailer. The Drotto boat latch is designed to replace the bow roller of your bunk trailer or roller trailer. There are many models and styles and variations of bow roller setups. Our Drotto boat latch is designed to replace your bow roller according to size. The 3″ model replaces your 3″ bow roller and the 3 3/4″ model is designed to replace a bow roller between 3 3/4″ and 4″ ( just add spacers or washers for larger rollers). The Drotto Bunk Trailer Install is simple in most cases. See below for further details on the Drotto Bunk Trailer Install process.

Step 1 

Locate the bow roller on your trailer. Here are only a few examples of bow roller setups below.

There are a number of different trailers. BUNK trailers and ROLLER trailers. The Drotto boat latch works on both styles of trailers. There are also a number of different bow rollers. The Drotto boat latch is designed to fit on the 3″, 3 3/4″ – 4″. refer to the “Drotto Boat Latch Sizes page” to learn how to measure your bow roller.

Step 2

Release the boat into the water. It is hard to move a boat on a bunk trailer, therefore we suggest simply launching the boat into the water.

Remove Boat From Trailer

Step 3 

Remove the single bolt holding the front roller on the trailer and remove the roller. Once roller is removed, replace it with the latch. Tighten the bolt snug, but not fully tight. The latch must be able to pivot a little with force, but not floppy.

Step 4 

Drive the boat very slowly back up onto the trailer or crank the boat back onto the trailer with your winch. You will then hear the click. Once you hear the click you know the latch has secured and locked the boat to the trailer. Then pull into the dry area and hook up your strap and chain for travel.

Double Roller Bow Stop Install

Here is a good visual if you have a double roller bow stop. In this version, simply remove the top roller, install the latch in place of the top roller and adjust the winch arm to line up the bow eye with the latching system. Another option is to remove the double bow stop completely and install the latch directly to the winch post.

I fish a lot by myself and am getting on in age. I needed something to assist me launching and recovering my 19 foot Skeeter. The boat2trailer large latch is perfect. It works as advertised and is the help I needed.

Seems like a very well built product, vert stout, was easy to mount. I have only used it twice but so far so good. I will repost in spring after many uses.

Works as good as they say it does if not better. I just need to learn my trailer depth when launching for an easier release. Picking up not so deep.

Products works as described, however I feel the company should be asking how wide the distance between the forks where the unit mounts to. I Purchased the larger unit that is only 3.625" wide. My trailers gap is 4.0" . Providing a wider unit instead of the customer buying stainless washers to make up the difference and a longer stainless nut and bolt to fit would have been nice.

Top notch company. I have owned three Drotto trailer latches. I have had them on both bunk and roller trailer without any issues. I won't own a boat without one. No more having my fishing partner or wife wade in the water to latch the boat. Makes easy for one person to unload and load if you by yourself. If I have ever needed a replacement part, it has only taken a couple of days to get.

Super easy install, high quality and it worked perfectly. Love it already, although I think my dry-footed friend loved it more. No more wading in to hook up the winch.

Amazing product. Best money I've spent for my boat. We can load the boat in about 15 seconds and be pulling out. Makes everything easier!

Almost perfect for my 2012 VS-621 Ranger boat. The boat is only 3" short of loading up on the trailer like it use to before B2T. Very acceptable.

Hands down the single best purchase for my boat, and immediate delivery was a bonus! Every boat trailer should have this!

Easy to mount. Catches the boat everytime, unless I drive over the top, not their fault! I like it!

The product works perfectly. I deducted one star due to the somewhat misleading shopping experience. I was lead to believe that shipping was free but upon checkout it became clear that it is free only if one enters a code at the very beginning of the process. Faced with a time issue and uncertainty over where to get the code, I was not able to find a way to completely start over and instead paid the shipping.

Well, only have used once. It was pretty hard to get latched the first time. Rough water really gave me fits. Relaunched and 2nd time it hooked up rather quickly. Hopefully will get easier each time I trailer boat.Put on tracker pro guide 16. Installed VERY easily. I bought their locks as it would be very easy to remove in parking lot. Hopefully it will keep honest people honest

package great shape, able to slid my Tracker 175 back far enough to mount on trailer, had to modify my winch hook but works like a charm. So much safer with this installed
