R&D has been working closely with Skat-Trak to develop the revolutionary Twin Prop (impeller) concept to work with existing R&D Engine and Performance Kit Packages. The Twin Prop concept works fantastic to eliminate detectable low speed or holeshot cavitation noticed on Pro Stock and Pro Limited Race Packages using the O.E.M. 6 vein pump assembly. The new Twin Prop design drives off the line much quicker than the traditional single prop, and offers a substantial increase in rough water hookup combined with the R&D Aquavein top loader scoop grate. R&D has done extensive testing to offer a range of pitch combinations that are packaged to work well using O.E.M. stock nozzle sizes for Pro Stock Classes where stock nozzles must be used. Stay tuned and call R&D for updates and specifications on this and other exciting new products and how they can be tuned to get the maximum performance out of your R&D Performance Kit. Note: All performance testing has been performed on High End Race Watercraft using MoTeC ECU Systems. Twin Prop combinations for stock and R&D Performance Re-flashed ECU’s will be developed soon.
