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.

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 yet. Keep slightly loose so the latch can move just a little.

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.

Step 5 

Simply snug up the bolt that secures the latch. You DO NOT want it extremely tight, It should be able to pivot slightly with the boat.

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.

Delivery was timely, but I did not install the device on my trailer yet as my mobility is limited recovering from knee surgery. I will revise my post in few weeks.

I fish a lot by myself and this piece of equipment is a must. Upon loading my boat onto the trailer it's pull up until it clicks. No more running up to hook the wench on before the boat slips back. Even easier when there's 2 people. Back down trailer, pull boat on, "click", pull up ramp and get out of the way. Finish hookup clear of the ramp. Must have!

Once I figured out that I needed to back the trailer in a little further during the loading process the Drotto has worked as advertised. I was able to install it at home using a small jack to raise my Lund enough to remove the existing roller. It has definitely speeded up the loading process.

I replaced my BoatBuddy that I have used for many years with this one and it blows BB out of the water by how easy it works and performs. I love that you don't have to set anything. It's all automatic and a lot safer as you don't unlatch it till you're ready to back off the trailer.

This is one of the best investments you can make on your trailer Simple installation and makes it very easy to launch and load by yourself or with a driver. I use it on my 23ft Keywest. And it save me a lot of time at the ramp.

I have a new SeaPro 208 boat and the Drotto Boat Latch fit perfectly! I had boat carpet added onto the white pads for extra protection. This is an outstanding product; it makes loading and unloading the boat much easier at coastal boat ramps. I was so impressed with this product that I bought one for my crappie boat for fresh water fishing. Great products! Very well pleased!

I think it is really great as I fish a lot by myself and this makes launching and loading a breeze. My only disappointment is that after I bought mine the priced dropped 20 dollars and the offered free gifts. I guess I should have waited!! Oh well.
