Installation order of the components is critical. Took more than one try to get it right.

  1. Install the winch bases. The five machine screws are 10-24 x 2?".
  2. Install the two pan head machine screws holding the coaming return blocks to the cabin. The top machine screw is 1/4"-20 x 2-1/4A." The bottom machine screw is 1/4"-20 x 2"
  3. Install loosely the six machine screws securing the coamings to the cockpit sides.
  4. Install the three 10-24 x 2?" machine screws securing the coamings to the winch bases.
  5. Tighten the six machine screws holding the coamings to the cockpit sides, but not so much as to distort the wood or place excessive stress on the winch bases.
