You can get a fairly good idea by measuring the distance (A) inside in the bilge from the trim tab bolts that come thru the hull bottom to the transom inside surface, then on the outside under the boat measure the distance (B) from the same trim tab bolts to the outside transom surface. B – A = Transom thickness
