Yes, it has an outboard. I have about 1-1/2” I can move the boat back. But the hull is already about 2” off the bunks. That is the way the trailer came from the mfr, and the trailer is made for the boat. I’m thinking of installing a Drotto auto catch to the trailer that will move the boat back about 1” (or so it appears). When I load the bait with gear, most of it is above the axles with some of it forward.Can you just move the winch post (or whatever the part is called that holds the winch on the front of your trailer) back to lower the tongue weight a bit? I assume your boat is either an outboard or inboard/outboard with most of the weight in the back. Moving it back even 4" could make a difference in tongue weight. Also you might want to weigh the tongue with and without a full tank of fuel.
I weighed the boat with a full tank. It is in the bottom under the cockpit but in front of the axles. I plan on adding a kicker outboard which will add about 100 lbs to the transom and lower the TW.
