The Drotto Boat Latch small model is very commonly used with Tracker, Nitro, G3 and all other boat and trailer setups that have a 3″ roller. The Drotto small model replaces a roller that measures between 3″ and 3 3/8″ wide. The best way is to measure the inside width of the actual bracket the roller mounts inside.
Drotto Small Model W Roller Specs
To install the Drotto Boat Latch small model simply back your boat and trailer into the water. Once your boat is floating simply let out some slack from the strap while keeping the safety chain attached. Push the boat back roughly 8 inches to give yourself room to work. Now remove the front roller or rubber V on your trailer. Once removed place the Drotto in its place and place the bolt through one of the 2 mounting holes. (typically the hole closest to the jaws is best) Now tip the Drotto to an angle that very closely matches the angle of the boat. Snug the bolt up. Now using your crank on your trailer crank the boat in until you hear the latch click, Now snug up the mounting bolt. This should be snug enough that the Drotto does not flop around, but you also do not want it real tight. It is best that it can move. Now that the Drotto latch is secure you can now install the release arm. Slide the thick spacer onto the side of the shaft you want the release arm to be on. Next slide the release arm on then install the coder pin to keep the Drotto handle secure. You are all set.
