INSTALL THE BRACKET
Mounting hardware is not supplied. Buy four 3/8-inch-diameter stainless-steel mounting bolts, long enough to reach through the transom with enough room to accept fender washers and locknuts. Garelick also recommends using a backing plate inside the transom. Coat the inside of the mounting flange and backing plate with a marine sealant such as 3M 4200 and squeeze some in each transom mounting hole. Bolt the bracket securely to the transom (you will need a buddy to help you tighten the bolts).
