The Worx Racing cast aluminum pump shoe serves as a superior alternative to the stock plastic pump shoe, which tends to deform or break at high speeds during races or when subjected to heavy strain from freestyle engines. This upgrade is essential for modified stand-up watercraft, as it comes pre-drilled and tapped for effortless installation. It enables the use of larger aftermarket intake grates with substantial wings, optimizing the efficiency of your jet pump without compromising reliability. Compatible with Yamaha Superjets and most aftermarket hulls.
