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 back up onto the trailer. Pull into the latch just above idle until you hear the click. Once you hear the click you know the latch has secured and locked the boat to the trailer.

Step 5 

Pull forward into the dry water’s edge and tighten the bolt for a secure fit. (Please note the latch should be able to pivot slightly when you apply force, but do NOT leave floppy loose.)

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 bought this last year and have loaded and unloaded my boat maybe 50 times since installing it. I am happy with it overall but I do have too mention to make sure you hook a safety chain to the boat before you pull up from the landing. I seriously wrecked my prop and lower unit because it didn’t lock. This unit has failed to lock on four other occasions. As long as I attached the safety chain on before I pull up the landing, I feel safe. Other than that, I am very happy with the unit. It does leave white markings on the front of the boat when you drive up to lock it.

I bought one after seeing it at the boat show. Of course I was skeptical at first because everyone says their instrument is the best thing since sliced bread. This time I am thrilled with this purchase it is the best. My friends are jealous and have been taking videos. I will never own another boat trailer that does not have this attached. I am amazed that manufacturers don’t offer to put it on your trailer when you order your boat. That’s not a big problem though it took less than 5 minutes to install and adjust.

Able to retrieve my boat and keep my feet dry. No more climbing out on the trailer tongue. These should be on every boat trailer!

I installed this on my boat trailer and it is an absolute must have. Makes loading and unloading so much easier and safer! Fishing the Green Bay this weekend and loading in rough water on the Fox River, this made load so simple! Can’t recommend highly enough!

This is a must for your boat trailer!!! Was planning to buy one of these since I fish a lot by myself. At my age at 62 at the time always had to climb over the bow of the boat to hook the trailer strap to the bow of the boat!!! After my stroke two years ago this is the cats meow after I got it!!!! Can't believe more people young or old haven't bought one of these???? Great product, been a life saver and it's worth the money!!!👍👍👏

Got this for my Dad last Christmas and he has loved it so far. He has a 19ft Crestliner with a roller trailer and musky fishes by himself quite often. Actually broke his hand because the boat flew off the trailer launching it a couple of years ago. Laid him up for 9 weeks. Now he just hits the lever while in the boat and drives it to the dock. He's a dentist so he kind of needs those hands. Well worth the safety, the convenience is just the cherry on top

Great product. Easy to install. Easy to use. Wish I would have purchased one of these apparatuses many boats ago.
