SPECIFICATIONS
The WMC 533 jet construction features are rugged composite materials for the main duct are incorporated. This gives light weight corrosion free main unit with the ability to mould the intake to the hull shape. The pump is a single stage mixed flow design which gives the most efficient performance for the flow rate and pressure to suit the vessel speed.
ENGINE SIZE
Diesel 600 to 1400 h.p.
Max. speed 1800 r.p.m.
Moment of inertia 1.89 kgm2 (45 lbft2)
IMPELLER DIAMETER AT INLET
533mm (21.1") left hand rotation. Range of impellers available to match power and r.p.m. Impeller clearance adjustment facility available as standard.
NOZZLE DIAMETER
Standard 343mm (13.5").
Other sizes available for optimisation.
BEARING
Front: Spherical roller thrust and radial
bearings, oil bath lubricated.
Rear: Water lubricated rear bearing.
Oil lubriacted as an optional extra.

CATHODIC PROTECTION
Comprehensive cathodic protection system terminating at single anode with easy access for maintenance.
MATERIALS
Parts moulded in rugged composite:
-Duct -Reverse deflector
-Steerable nozzle -Hand hole cover
Casting in Aluminum bronze ASA957:
-Bearing housing -Clamp-bearing
-Stator and Impeller
-3 or 4 blade mixed flow impeller 533mm diameter
-Hydrodynamic low loss intake grill (single point fixing)
Parts manufactured in stainless steel 316
-Shaft -Bolts, nuts etc.
-Wear ring (to resist abrasion)
CONTROLS
Control forces on steering and reverse are balanced and nominally zero. Hydraulic rams are built into the jet for simple operation and
complete power assisted systems can be matched to the particular boat requirements.
COUPLING
The shaft terminates in a tapered and keyed section and a coupling flange can be provided to match the desired intermediate shaft.

The WMC533 Jet Unit is
designed as a light weight
system principally for planing
craft. The construction of
the duct is from rugged
composite material making it
easily adapible for different
hull configurations or
multiple layouts. It is also
suitable for displacement
and semi-displacement hulls,
subject to hull shape and
application.
