Parts/Kit Overview

The R&D Yamaha GP 800R Performer Kit was developed to improve overall handling, reduce pump cavitation, and increase top speed performance without engine modifications! The entire Performer Kit installs quickly and easily with basic hand tools. The R&D GP 800R Performer Kit is 92-Octane pump gasoline safe.

  • The R&D GP 800R Ride Plate is extended and re-angled over stock to reduce porpoising while adding top speed. The R&D GP 800R Ride Plate is the only aftermarket design to dominate in Offshore, National, and World Championships, and to be used and endorsed by Factory Yamaha racing teams for 3 years!

  • The R&D Aquavein Intake Grate Kit will substantially reduce cavitation, increase overall handling dramatically and add a 3 to 4 mph average top speed in choppy water conditions!

  • The R&D Pump Shoe Sealer Kit was developed to quickly and easily fill the large casting pockets left in the Yamaha GP 800Rís pump shoe inlet. Installing the R&D Pump Shoe Sealer Kit and resealing the pump shoe will reduce low and high-speed cavitation, which will increase overall handling!

  • The R&D Anti-Cavitation Cone was developed to reduce low speed pump cavitation, which will increase acceleration and pump efficiency.

  • The R&D/Solas 11/14 Impeller replaces the O.E.M. impeller with a sleeker, better performing 3-blade design! Improved low-end response and increased top speed performance of 1 mph plus!

  • The Yamaha GP 800R Power Plenum Air Filter Kit will eliminate the O.E.M. air box and replace with a large volume, high flow, high performance design! The R&D Power Plenum will add to low-end response and acceleration. The R&D design also allows easy access to high-speed fuel turn jets!

NOTE: The O.E.M. power valves are manufactured from a cast aluminum material and are notorious for shearing or breaking after 40-50 hours, creating costly engine damage! R&D manufactures a redesigned 6061-T6 Billet aluminum Power Valve, and Power Valve Lifter Arm Kit that adds low-end power, and assurance against breakage! Part # 332-12002
