Worx Racing cast aluminium pump shoe is a direct replacement for the stock plastic pump shoe that easily distorts and breaks under high speeds in race applications or under huge load from freestyle engines. Pre drilled and tapped for easy installation this is a must have upgrade for your modified stand up to allow use of larged winged aftermarket intake grates that provide maximum efficiency to your jet pump without sacrificing reliability. Suits all Yamaha Superjets and most aftermarket hulls
