  • The R&D performance ride plate, which is specifically designed for the FX H/O 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 O.E.M. speedometer is relocated to the rear of the plate for higher speed accuracy.

  • 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 become over oil saturated, making it the only replacement choice! Easy to install in 5 minutes, adds a great sound tone, and adds RPMs.

  • The R&D FX H/O Power Plenum Filter Kit will add low end and mid range performance to the Yamaha FX H/O by replacing the restrictive flame arrester system with a high flow, high velocity air filter/velocity stack design combination! R&D Performance filters have been dyno tested on 4-stroke watercraft engines to in excess of 300 H.P.! R&D Power Plenum Filter Kits install quickly and easily, and add a great high performance sound to the Yamaha FX H/O!

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

  • The R&D Yamaha FX H/O Aquavein Intake Grate has been in the design, development and testing stages for 2 years! The new R&D FX H/O Aquavein will significantly reduce cavitation, increase acceleration, add up to 1 mph on top end performance, and keep the H.O. pump loaded and hooked up! Works great on aftermarket supercharged models as well.

  • The R&D/Solas 14/20 Dynafly Impeller will add new found RPMs and top speeds to the Yamaha FX H/O The Dynafly Impeller installs easily and is a great replacement over damaged O.E.M. impellers.
