•
Make sure that the drive unit and adaptor pin bracket do not
come into contact with any part of the engine, boat or steering
system.This includes any engine hoses that may have a

relative to the girdle tube (see Figure 18).
Installation for Mercruiser 95
CAUTION:
Before you install any of the autopilot components, make sure
there is sufficient space between the complete drive unit and the
engine manifold.
Use Raymarine installation kit D309 to install the I/O drive unit to
Mercruiser engines manufactured from 1994 onwards.
Install the I/O drive by following these steps:
1. Remove the existing pins securing:
•
the tiller and twin engine connecting bars:
•
the power steering ram to the tiller arm and twin engine
connecting bar.
•
the steering cable to the power steering ram.
Note: These pins are retained by split pins that may be hard to
remove. You will probably need someone’s help to hold the legs of the
split-pins together so you can remove them.
2. Fit the pivot assembly to the steering system as shown in
Figure 11:
•
use the new retaining pins (supplied with the installation kit)
•
secure these with the split pins (supplied)
