How To Determine Which Fulton Coupler Hinge Kit For Boat Traier


Hi, Im looking at getting a 91 Bass Tracker ProV 16FT boat and the trailer is a 91 Tracker Trailstar, I dont know what size the frame is on the trailer but I need to get a fold away hinge for it so it can fit in my garage. Could you help by telling me what size fold away Trailer Coupler to get.

You will want to measure the size of your trailer tongue to determine what size hinged coupler kit is needed. The hinged coupler kits fit the 2 x 3 inch, 3 x 3 inch, 3 x 4 inch, and 3 x 5 inch tongue size.

You will also want to make sure when installing the hinged coupler kit that the distance at which you install the hinge on the trailer tongue will still allow you to maintain the correct weight capacity and tongue weight for your boat and trailer.

The Fulton Fold-Away Coupler Hinge Kit, part # FHDPB330301, which you referenced, will fit a 3 x 3 inch tongue. The maximum distance (pivot length) you will want to mount the hinge on the tongue is 34 inches. This would create a 34 inch foldaway tongue on your boat trailer. At that distance the gross trailer weight capacity it can handle would be reduced to 3,500 lbs and the tongue weight would be 350 lbs. The hinge kit can be mounted up to 24 inches and still maintain the 5,000-lb gross trailer weight capacity and 500-lb tongue weight capacity.

For the best and safest ride, you want to install the Fulton coupler hinge kit so that the coupler ends up being about the same position as the original coupler to retain the same tongue weight and lessen the chance of failure.
