SeaStar HA5418 Back Mount Kit for SeaStar Front Mount Helms

The SeaStar HA5418 Back Mount Kit is designed for boats being upgraded to a SeaStar front mount helm. When a front mount helm replaces an older steering system, the new helm's mounting pattern does not always line up with the existing dash holes. The HA5418 kit covers those leftover holes for a clean, finished look on the dash while also adding extra rigidity to the mounting area, which helps support the new helm during steering.

This kit is intended for boats that are upgrading from SeaStar Solutions rotary mechanical steering (Safe-T, Big-T, or rotary NFB), a pre-1991 SeaStar helm with a square mounting flange, or SyTen steering. In these cases, the HA5418 kit is the correct choice because it covers the old holes without requiring the dash cutout to be enlarged. Boats upgrading from SeaStar Rack & Pinion or Morse mechanical steering instead require the dash holes to be enlarged, and may use the separate HA5405 Backing Ring Kit rather than this kit.

The kit has a polycarbonate outer construction with a foam backing and is finished in black to blend in with most dash and helm setups.
