PREPARATION:—After mounting the Intake Block
and making the Transom hole in the hull:-
1. Ensure that the Reverse Duct and Transom Plate
have been removed from the Jet Unit as shown in
Section
9.2.1 Reverse Duct Removal and
9.8 Transom Plate Assembly
Reverse Duct needs to be removed because the
Jet Unit is installed from inside the hull, and the
Reverse Duct cannot fit through the Transom
hole.
2. To fit the Jet Unit complete with the Intake Screen
attached, using approved lifting equipment, lift
the Jet Unit with the Intake Screen attached, into
the hull and position the Jet Unit so that the rear
of the Jet Unit passes out through the Transom
opening and the Intake Screen fits centrally in the
Intake Block hole. Should the Intake Screen
require removal during installation, refer to
Section
9.10.4 Screen
3. Check that the Jet Unit is correctly located in
relation to the Transom hole and that the Intake
Block fits neatly with the Intake casting. Correct
the hull preparation as necessary.
4. Check that the contours between the hull and the
Jet Unit Intake, at the front and rear are smooth
1
to within 1mm (

"). There should be no steps.
