Introduction

Product description

W elc ome to the i nstallat ion guide f or the Ra ymarine u niversal
inboard/outboard drive (also known as an I/ O or stern drive). This
product is intended to operate the boat’ s steering mechanism as part
of a Raymarine autopilot system.

This drive is only designed to drive cable operated, power
assisted steering systems. Any attempt to install an I/O drive to a
