Edge Mount Kit Upgrade
Since the placement of the upper bracket is lower then a standard mount, an edge mount can be retrofitted only with another edge mount trim tab.

Edge Mount Tab to Troll’n Tab
The only Troll’n Tab kit that can upgrade from an edge mount trim tab kit is the TNT 12x12/24 DVNS A 12x12E trim tab can be upgraded to a 12x12 Troll’n Tab.

Note: In order to utilize the same mounting holes when upgrading from trim tabs to Troll’n Tabs, the trim tabs have to have been mounted with the hinges at least 3/8" (.95 cm) from transom bottom as recommended in Lenco installation instructions.
