Installing the Base on Your Boat

Decks up to 7/16" thick

Where access to the underside of the deck is not available, the mounting base can be mounted using wellnuts. Use the base as a template to mark locations and drill four 1/2" holes. Mount the base using four 1/4"-20 x 1 1/2" truss head screws and four wellnuts. Tighten the screws so the wellnuts are firmly compressed as pictured.

Decks thicker than 7/16"

For decks thicker than 7/16", or where the underside of the deck is accessible, mount the base with screws, nuts, and washers. Use the base as a template to mark the locations and drill four 9/32" holes. Use four 1/4" -20 x 2 1/2" truss head screws and four each flat washers, lock washers, and nuts. Fasten the base to the deck as pictured.

NOTE: Wellnuts cannot be used on decks thicker than 7/16".
