What to Compare Before Buying
- Seat post fit: Check that your post uses a 3/4-inch non-threaded pin connection; the stated size alone does not establish fit with every post.
- Deck space: Compare the 7 x 7-inch plate with the mounting area and verify room for the specified center hole and below-deck clearance.
- Fasteners: Six screws are not included. Check what screws suit your mounting surface and installation.
Setup and Correct Use
The described installation uses a 2.5 to 3-inch center hole, at least 2.5 inches of below-deck clearance, and six screws. Confirm the location and clearance before drilling, and follow the applicable instructions for the boat and mounting surface.
Before You Decide
Confirm the post connection, plate footprint, deck opening and clearance, and plan for the six screws, which are not included.
