Parts/Kit Overview

The Sea-Doo GTX 4Tec N.A. 155 H.P. Performer Kit was developed and tested to deliver a noticeable increase in top speed performance, while enhancing low and mid-range performance. The R&D GTX 4Tec Performer Kit also increases straight line stability, along with added low and high speed cornering stability! The R&D Performer Kit is very easy to install and each part in the Performer Kit can be used individually as a “stand alone” product. With the R&D Sea-Doo 4Tec Performer Kit you can expect to receive a noticeable performance gain, with great reliability, at a very reasonable cost. The R&D GTX 4Tec N.A. (155 H.P.) Performer Kit applies to 2003/2004/2005 models. NOTE: The Sea-Doo GTX 4Tec models do not have any form of stock variable trim system. R&D Performance offers a fully adjustable automatic trim system that is one of the finest parts that can be bolted on and preference adjusted to give the rider of any caliber or weight the type of ride they want!

  • The R&D GTX Aquavein Intake Grate will keep your Sea-Doo GTX’s pump loaded and hooked up to improve handling and top speed performance. Improved straight-line stability and smoother, tighter turning capabilities will be noticed instantly! Also, there is no speed loss with the R&D Aquavein Grate. In fact, speed improvements have been noted.

  • The R&D 2.5 degree Pump Wedge Kit was developed for the new Sea-Doo GTX 4Tec model to reduce hunting or bow searching at top speeds. The R&D Pump Wedge Kit will increase straight-line stability and will a 1 mph boost in top speed!

  • The R&D GTX 4Tec N.A. Power Plenum Filter Kit was designed and developed exclusively for the new Sea-Doo 4Tec 155 H.P. naturally aspirated models. The R&D Filter Kit will sound good, look great, and will add up to 100 peak rpm’s to your tachometer reading, which will add up to 1 mph to your top speed performance.

  • The new R&D/Solas 11/19 Impeller Option has a sleeker 4-blade design, with a high-performing polished finish. Reduced cavitation, increase acceleration and a top speed improvement of 1 mph can be expected.

  • The R&D O.P.A.S. Removal Kit was developed for closed course, and off-shore competition to improve turning, rough water handling, and top speed.

  • The new R&D GTX 4Tec Pro Series Sponson Kits main feature includes an ultra strong cast aluminum CNC machined backing plate, which is far superior over plastic backing plates with furniture inserts for threads! The R&D Sponson Kit offers 2-position sponson blade adjustability, which will guarantee this kit to out perform any other 1 up, 2 up or 3 up. The R&D Pro Series Sponson Kit offers a smoother more predictable ride with much better low and high speed turning capabilities. Track tested and race proven!

NOTE: The Sea-Doo 4Tec Performer Kit development, tachometer, and top speed information posted was gathered after an initial 5-mile warm-up to stabilize engine temperatures. All testing was performed exclusively with Chevron 91 octane pump gasoline at 500 feet above sea level. Ambient air temperature during testing in May was between 90 and 110 degrees. These test results may change as we continue to gather data, and monitor O.E.M. stock boat speed averages, and production impeller consistencies. The information posted in the R&D Performer Kit are averages. In many cases we hear of feedback from Sea-Doo owners with performer kit packages reporting of higher speeds than posted.
