Parts/Kit Overview

The R&D Yamaha FX-140/FX CRUISER Stage 1 Performance Kit was developed to significantly improve handling and overall engine performance with easy to install entry-level performance parts. Each component part listed can be installed and used as a stand-alone product. The R & D FX-140 Stage 1 Kit has been in the testing and development stages for two years, creating a ride plate and sponson kit combination that will eliminate the annoying hunt or bow search noticed while riding at top speeds. The addition of the R&D Stage 1 Performance Kit will transform the FX-140 or FX-140 Cruiser into one of the best handling watercraft on the water. Order up some fun today!

  • The R&D Performance Ride Plate is increased in length over stock and has a steeper rocker section, which will add top speed and eliminate the hunt or bow search noticed in the stock ride plate. Also, smoother and tighter turns can be carved and straight-line stability is significantly increased.

  • The R&D Sponson Kit is a two-stage design and has 3 adjustable positions. The unique blend of a long bullet shaped 6 degree backing plate and a short (GP 1200 R) style sponson blade will significantly improve low and high speed cornering capabilities, and add unmatched straight line stability.

  • The R&D Solas 13/19 Impeller will increase hook-up, acceleration and top speed performance.

  • The R&D Power Plenum Breather Kits unique design will flow much more air than the O.E.M. filter. O.E.M. filters are notorious for becoming over oil saturated causing sluggish low-end power and a loss of up to 500 RPMs! The R&D replacement breather will never over oil saturate, making it the only replacement choice! Easy to install in 5 minutes, adds a great sound tone, and adds RPMs.

  • The R&D Power Plenum Twin Flame Arrester Kit will add a noticeable gain in low-end throttle response over the O.E.M. flame arrester, and adds a high performance sound to the FX-140!

  • The R&D pump shoe sealer kit will seal up the FX-140s pump shoe and pump inlet to promote reduced cavitation, much better hook-up, and add top speed performance.

  • The R&D FX-140 pump cone was designed to increase bowl pressure in the pump venturi nozzle. The R&D pump cone reduces cavitation and increases pump efficiency.

  • The R&D FX-140 Aquavein Intake Grate will reduce overall pump cavitation and add a 2-3 mph average top speed in choppy water conditions over the O.E.M. intake grate.

  • The R&D FX-140 steering nozzle kit was developed to work in conjunction with the Solas 13/19 or higher degree impellers! The larger bore and lack of straightening veins will help to raise RPM levels through tight turns!

NOTE: For proper RPM and performance of the Solas 13/19 Impeller, it will be necessary to bore the O.E.M. Nozzle out plus 1 mm (.040).
