5.8 INSTALLING THE HSRX
REVERSE SYSTEM
Refer to Drawings HJ-241-07-001 Reverse Assem-
bly Sht1 & 2.
1. Prior to inserting the Jet Unit through the
Transom hole, remove the Reverse Duct as
instructed in the Overhaul Section of the Jet Unit
Manual.
2. After the Jet Unit has been mounted in the vessel
and the Reverse Duct has been re-fitted, connect
the HSRX Reverse Cylinder to the Reverse Duct,
ensuring that the Reverse Shaft Assembly is
orientated the same way as it was previously.
3. Ensure that the dot on the end of the Reverse
Shaft Assembly is positioned uppermost. If the
Shaft Assembly is 180° out of position, with the
Cylinder correctly mounted, the HSRX Reverse
will not work properly. To correct a wrongly
positioned Shaft Assembly, with the cylinder
correctly mounted, remove the pin which
connects the Shaft Assembly to the Reverse duct
and rotate the Shaft Assembly using an
adjustable wrench on the Shaft Assembly end
flats. Do not grip the Shaft Assembly itself as
surface damage on the Shaft Assembly will
damage the Cylinder Seals.

5.8.2 Cable Installation
The HSRX Reverse System is supplied with a cable
mounting plate (fitted to the end of the HSRX
Cylinder).
The recommended cable is the Morse 33c Supreme
(low friction) cable. The Cable Mounting Plate has
been designed to suit this cable.
A suitable controller is the Morse "S" Controller
which can be fitted with a
"Neutral Detent and
Engine Start Interlock" microswitch. This
microswitch prevents the engine from being started
with any other than the "Neutral" position selected
on the Reverse Controller.
Refer to Drawing CT-
CLV-01-003 Reverse Controller.
CABLE RUNS SHOULD NOT EXCEED 12m . Cable
runs above this length could result in a reduction in
Reverse Duct control quality.
MINIMISE THE NUMBER OF BENDS. The diagram
illustrates the ideal arrangement for a dual station
system. Total bend angle per cable in this system is
180º.
Do not exceed 360º per total as this will
result in excessive lost motion (backlash) .
Cable "Station Exchanger" systems may allow
reduced cable length and bends but tend to
introduce excessive lost motion (backlash)
themselves. For cable runs longer than 12m, refer
to
Section 5.8.4 Alternative Remote Operating Sys-
tems .
