PERFORMANCE EXIT NOZZLE
The new R&D cast aluminum exit nozzle is designed
to fine tune the pump and prop to maximize
performance and rpm. The new R&D exit nozzle is
available in 2.5 and 5 degree up sweep angles. The 5 degree positive angle
lightens the nose of the craft and adds top speed; this is great for recreational
use. The 2.5 degree delivers improved performance in rough water conditions
by producing more nose pressure to drive the hull through the bumps; this
design is perfect for closed coarse and offshore competition. Both types are
available in bore sizes of 80, 80.5, 81, and 81.5. *Custom bore sizes from 80
to 90 available at no extra charge, specify size when ordering. The mainte-
nance free R&D cast aluminum and powder coated one piece construction
exit nozzle is the better alternative to a removable ring design. With the new
R&D nozzle the OEM reliability and safety is retained, because there is not a
removable ring sleeve to vibrate loose, falls out and gets wedged in the
steering nozzle creating a whole new definition to the term BUCKING.

RIVA FX-SHO/FZ PRO-SERIES
REDUCTION NOZZLE
Our Pro-Series Reduction Nozzle is ideal for
tuning your Yamaha pump combination to
maximize performance. Nozzle exit diameter can
be easily changed via interchangeable ring
system. Looking for more RPM or acceleration power? Insert a larger
diameter ring. Want more top speed or less RPM? Install a smaller diameter
ring. Nozzle includes three precision-machined stainless steel rings in
graduated sizes (81, 82 & 83mm). Additional ring sizes available.
Note: Nozzle eliminates water spout function to maximize performance and
conform to racing safety rules.

ANTI-CAVITATION CONE
The R&D Anti-Cavitation Pump Cone Kit will reduce
overall internal pump cavitation within the Yamaha's offset
reduction/compression nozzle design. The O.E.M.
reduction/compression nozzle is offset, while the O.E.M. pump cone/bearing
cap remains straight which causes uneven pressures within the pump and
reduction nozzle. The R&D Anti-Cavitation Pump Cone is offset and
reshaped to match the O.E.M. reduction nozzle offset promoting even pres-
sures, which will substantially reduce cavitation, increase pump hook up,
boost acceleration, and increase top speed performance.

MACHINING
MODIFICATION
R&D’s new SHO/FZR Anti-Cavitation
Transom Plate Machining Modification service is now available. The
engineers at R&D have been successful at reducing pump cavitation by
removing the restriction in the OEM Transom Plate. The OEM Transom Plate
has a 3mm taper that restricts water flow in front of the prop. Removing this
restriction significantly reduces cavitation and improves holeshot and hook
up with any prop type or diameter. The service includes line boring the
Transom Plate and blue printing the new pump shoe diameter to blend with
the R&D Aquavein Intake Grate, and the sealing surface of the transom
plate where it mounts the hull is also improved by plugging the OEM casting
pocket in the face of the Transom Plate with R&D’s Sure Seal Urethane
Material. R&D also offers the service to a new OEM Transom Plate available
for immediate shipping.

SLEEVE KITS
RIVA’s precision machined Billet Driveshaft Sleeve is a direct replacement for
the thin factory rubber hose that is prone to distortion and failure. Sleeve is
constructed of 6061 aluminum and is anodized to prevent corrosion. Kit
includes high quality silicon couplers and stainless steel clamps. This
upgraded sleeve kit is highly recommended for performance applications due
to increased pump pressure that accelerates failure of original rubber hose.
