Sht1 & 2. If removed, the Reverse Cylinder may now
be re-fitted to the Jet Unit in accordance with the
instructions at
Section 9.3.1 Reverse Cylinder: Refit to
the Jet Unit.
5.5.2 Reverse Duct Fitting

STEERING CYLINDER FITTING.
Refer to Section
9.5 Steering Assembly Re-Fitting and
Drawing CT-SJK-02-005 Steering Cylinder, Seastar
for the re-fitting of steering components.
1. The boat builder is to mount the Steering
Cylinder to provide equal travel on either side of
the centre position to ensure that the Steering
cylinder reaches the end of its stroke, in both
directions before the Steering Nozzle reaches the
limit of its travel.
2. Refit any Sensors attached to the Tiller. Refer to
the Overhaul Section of the Controls Manual.
PUSH PULL CABLE SYSTEM:
Refer to Drawing
CT-HLM-06-002 Helm Wheel Op-
tions .
1. This is a steering option and is not "Standard Fit"
for the HJ-241 Jet Unit.
2. If choosing a Push-Pull Cable, use a heavy duty
Rotary system or a Rack and Pinion system. For
lightest steering action, keep the number of
bends in the cable to a minimum and ensure that
bend radii are as large as possible. Make sure
cables are well lubricated prior to installation.
3. The cable should be connected to the lower hole
in the Tiller Arm for all single Jet installations. In
the case of multiple Jet installations, the outer
hole may be used to reduce the helm load if
necessary.
5.5.4 Assembling the Jet Steering
Tillers
The Jet Tiller as supplied, is pre-drilled for
attachment of the tie rod bolts. The Tiller has been
drilled with a series of holes in the surface of the
Tiller. These holes are spaced at 5º intervals.
Refer
to Drawing CT-SJK-02-005 Steering Cylinder, Seas-
tar in the drawings package.
The position for attaching the Tie Rods to the Tiller
to suit the different deadrise angles is at an angle
from the Jet centreline which is equal to the deadrise
angle. Attach the Tie Rod to the Tiller at the nearest
appropriate drilled hole on the Tiller. For correct
fitting and positioning of the Jet Unit Tillers and Tie
Rods for Twin and Triple Jet applications,
refer to
Drawing HJ-241-06-000 Steering Assembly General
Arrangment Sht2.
NOTE: Ensure that the Cotter Pin is fitted as shown
in Drawing HJ-241-06-000 Steering
Assembly General Arrangment Sht1 for all
applications of Tiller orientation.
SINGLE JET INSTALLATIONS:
Refer to Drawing
CT-SJK-02-005 Steering Cylinder,
Seastar for Steering Cylinder attachment.
Assemble the Cotter (taper) Pin in the Steering Crank
as shown in
Drawing HJ-241-06-000 Steering As-
sembly General Arrangment Sht1 & 2
TWIN JET INSTALLATION:
Refer to Drawings
HJ-241-06-000 Steering Assembly
General Arrangment Sht1 & 2 .
Ganged control of steering in multiple Jet
installations is achieved by swivel ended Tie Rod(s)
interconnecting the Jet Tillers. An adjustable length
Tie Rod is supplied to facilitate accurate centreing of
the Jets.
An“Adjustable Tiller” for Tie Rods can be fitted to
the Steering Shaft to facilitate steering tiller
adjustment to compensate for various hull
deadrises.
TRIPLE JET INSTALLATION:
Refer to Drawing
s HJ-241-06-000 Steering Assembly
General Arrangment Sht1 & 2.
One Steering Cylinder only is required which should
mount on to the “Adjustable Tiller” fitted to the
Center Jet.
