5.2.1

Planning

It's important to consider the harness routing when preparing to install the
actuator. The actuator harness on all configurations must have enough slack
to accommodate both the steering movement and the trim/tilt movement.
The minimum bend radius for the harness is 3.5" (90 mm). See section 5.3
for more information on the harness.
NOTE
On a multi-engine system, write down the serial numbers before installing
the actuators and note which is port and which is starboard. You will need
this information when configuring the system later, and they may be hard
to see once installed.
5.2.2 Actuator installation
Find the assembly drawing on the subsequent pages that matches your
engine application. You will need to refer to it as you follow the
installation procedure.
NOTICE!
Take care not to damage the actuator shaft when handling and installing
the actuator. Scratches and dings may result in water entering the
actuator and damaging it.
Procedure
1. Remove any caps, plugs, or screws from the engine's steering arm and
tilt tube. Check that the tilt tube and the threaded hole for the tiller bolt
is clean and free from rust or burrs.
2. Install the internal tooth terminal of the ground strap to the engine
midsection (see section 5.2.3) and hang the strap over the transom,
underneath the tilt tube. It is easier to access the midsection mounting
hole before the actuator is installed.
3. Thread the adjuster nut (item 10) onto the starboard side of the tilt tube
as far as it will go.
4. Liberally grease the support rod (item 9) with a quality marine grease
and slide it through the engine tilt tube.
5. Review the assembly drawing to determine the orientation of the
actuator (item 13), the tiller bolt (item 2), and self-locking nut (item 1).
Grease the tiller bolt and, while holding the actuator in position, fully
thread it into the steering arm and through the pivot plate. Install the
self-locking nut finger tight to hold the actuator in place. Tighten the
tiller bolt to the indicated torque.
6. While holding the head of the tiller bolt with a wrench, tighten the nut
(item 1) to the indicated torque.
WARNING!
Failure to correctly install the tiller bolt and self-locking nut may result in
loss of steering, which could lead to a collision and/or ejection from the
boat, causing property damage, personal injury, and/or death.
