Dealer tells me at level the LoadRite ball receiver sits 18.5” high.We have a 13 foot smokercraft as well, with a 15hp tiller, on an EZloader trailer. We are using a 5 1/4" drop and run perfectly level. Do not recall the height of our boat tongue, but we bought the draw bar to match after we lined up the truck and boat.
Good advice! However, this small boat and the geometries of the boat, trailer, and outboard to not support the use of a transom saver. We thought about this and searched around for solutions, but ended up being satisfied by keeping the motor from bouncing on the trim adjustment.
