9. Smear RTV Sealant [7] on the top of the Gasket
[17] and run a bead of RTV Sealant around the
internal corner of the prepared recess.
10.Ensure that all the Bolts [18] are liberally
smeared with RTV Sealant prior to fitting.
11.Install the Intake Block and secure in 3 positions
with Bolts [18], Nylon Insulating Bushes [19], Flat
Washers [6], Spring Washers [5] and Nuts [4].
Hand tighten.
12.Check for electrical isolation between the Intake
Block and the vessel Hull before fitting the
remaining bolts.
13.Fit the remaining Bolts [18], Nylon Insulating
Bushes [19], Flat Washers [6], Spring Washers
[5] and Nuts [4].
14.Torque load all the Bolts and Nuts incrementally
to the recommended torque.
15.Once the Intake Block is installed, check again for
electrical isolation and then fill any gap at the
edges and corners with RTV Sealant. Clean off
any excess Sealant and trim off any protruding
part of the Intake Block Gasket [17].
5.2.2 Transom Preparation
An area at 95º to the Jet Intake base has to be
prepared as shown on the appropriate Installation
Drawings.
FOR GRP AND WOODEN HULLS:—Drawing HJ-
241-08-001 Installation Details GRP Hull .
• An area of 95º to the Jet Intake Base has to
be prepared as shown on the Hull Prepara-
tion Drawing.
• An insert can be taped into the Hull mould
so the required area at 95º can be moulded
with the Hull.
• Alternatively, the area to be at 95º can be
cut from the Transom and re-fibre glassed
back at the correct angle. One method to
locate the cut-out Transom at the correct
angle is to install the Jet Unit, bolt the
Transom Plate assembly and Transom cut-
out into position on the Jet, then fibreglass
the cut-out back into the Transom.
FOR METAL HULLS:— If the Transom is not close to
the angle required, cut out the required area,
reposition at the required angle and re-weld back to
the Transom with any necessary inserts at the sides
and top.
5.3 EQUIPMENT PREPARATION
Do not unpack the Jet Unit until it is required for
installation. This prevents mechanical damage
and entry of foreign matter. Unpack carefully to
prevent damage and loss of small items.

The Jet Unit is shipped complete with the steering
components attached. It should not be necessary to
remove any steering components prior to
installation.
NOTE: For Hydraulic Steering options only, the
Steering Cylinder will be supplied separate to
the Jet Unit. The boat builder will be
responsible for attaching the Steering
Cylinder to the vessel on completion of the Jet
installation.
If problems occur with installation, refer to Section
9.4 Steering Assembly Removal and Overhaul and
Section 9.5 Steering Assembly Re-Fitting , drawings
CT-SJK-02-005 Steering Cylinder, Seastar and CT-
HLM-06-002 Helm Wheel Options for removal and
refitting instructions.
5.3.2 Reverse Components
Drawings HJ-241-07-001 Reverse Assembly Sht1 &
2 refer .
The Jet Unit is shipped complete with the Reverse
Cylinder and Reverse Duct attached. If, during
installation, the Reverse Duct needs to be removed,
refer to Section 9.2 Reverse Assembly Removal and
Overhaul for the removal and refitting procedure.
1. Remove any Position Sensors and Linkages
attached to the inboard end of the Reverse
Cylinder.
2. Take care to label all electrical terminals for
correct re-assembly.
3. Make every effort to remove sensors in such a
way that they can be replaced with minimum
disturbance to their original position. Refer to the
Controls Manual supplied with this Jet Unit for
further information.
