For those that have the 2013 model swivel board racks (i.e. came on a 2013 boat or had the 2012 racks that hit the tower replaced)

The detent depth doesn't appear to be great enough for the plunger pin to properly engage and "lock" the rack in place. Inspect the plunger pin when it is seated/locked and if there is more than a 1/8" gap, contact your dealer and use caution until fixed.

If your dealer is too far away and/or you want to take care of this yourself, you can take apart the swivel & drill out the detent so that the pin can fully engage.
