550 Hull extensions

Kawasaki 440 & 550 Hull Extensions

The ProWatercraft Racing HFC Hull Extensions are a cap replacements for the Kawasaki 440/550. The stock 550 hull end caps eventually loose their bond and become water containers that weigh down the read end. With the replacement of the caps, you reduce the overall weight of the ski, integration of a rear exhaust, and add unmatched styling to your jet ski. These act as a hull extension, which reduces porpoising and increases the overall handling of the ski. Kawasaki 440/550 Hull [...]

Lip Front sponsons

36″ Upper Lip Front Sponsons on Kawasaki X2

Matt Goade from Retro racing worked with us to test our new upper lip front sponsons. Retro racing has a long background of adding perfect handling to their vintage skis from X2 to 440/550/650, etc. Matt and I are very surprised to how well the upper fin worked with the stock exhaust hole. “For an entry level rider, that stability is spot on”, Matt said. The install was easy because of the exhaust hole put the left side sponson in the correct spot [...]

Kawasaki pump shoe

Kawasaki HFC Pump Shoe

This ProWatercraft Racing pump shoe should fit Kawasaki 650sx, 750, 800, and X2 models with 140mm pump. The opening fits 140-145 mm to fit the stock Kawi pump that is similar to the 750/800.

On top of all that our product has a hydrophobic surface, which speeds up water. You will gain acceleration and top speed with all of [...]

SuperJet & Waveblaster pump shoe

Yamaha Superjet & WaveBlaster Pump Shoe (HFC)

Our PWR Yamaha SuperJet & WaveBlaster pump shoe was created from the OEM Yamaha Superjet pump shoe. We cut back the “shoe shape” to open up the intake to improve cavitation and hook up. Because, one of the more noticeable issues with the older Yamaha Super Jet and Yamaha Wave blaster is cavitation in the turns when the ski is really leaned over. The pump shoe is the best way to adjust this issue. The opening is 144mm to fit [...]

Kawasaki 440/550 HFC Pump Nozzle

This futuristic nozzle is a blend of old technology with a Jet fighter modern look. Here’s what we did: We extended the nozzle 1″ to offer better straight line hook up and drive. Also that longer nozzle will give you a tighter turning ratios, like a quick steer, but without making the turning action sensative. The ProWatercraft Jet Nozzle is a couple mm smaller ID, than stock 85mm Inner Diameter, why did we make it smaller? Generally the size of the thrust [...]
