WORX KAWASAKI 750 SXI. Worx PN WR203. MAXILOADER INTAKE GRATE This was the first of the larger stand-up Jet Ski produced by Kawasaki and dominated racing for a number of years. Although larger than the previous 300, 440 and 550 models a similar hull design was used with the same result: poor hook-up in most conditions without an after market intake grate. Performance Benefits Designed initially when all of the pro riders were riding this model Kawasaki. This intake grate will transform your boats performance in all water conditions, with increased pump loading and allowing you to keep full power on even on those really tight turns. fits 750sx and sxi.
