Kawasaki 440 / 550 Extended Jet Pump Nozzle

(5 customer reviews)



Our Extended Jet Pump Nozzle is 1″ longer than stock 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 sensitive. The ProWatercraft Jet Nozzle has a couple mm smaller ID than the stock 85mm. Why did we make it smaller? Generally the size of the thrust outlet should be 4-6mm smaller than the steering nozzle. On the 550 (depending on the year) the thrust nozzle is 65mm and the stock steering nozzle is 85mm, 20mm difference! What we did is make it only 2mm smaller, but with it being 25mm( approximately 1″) longer this will help the rider feel the steering without having it become over sensitive.

Let’s talk about the inside shape of the pump nozzle,  does it matter? Yes! Typically steering nozzles are “bell” shaped. However the inside bell shape disrupts water flow which makes turning aggressive and not smooth. Our designer has come up with the best shape for this standup. When compared to stock you should feel a smoother transition into the turn and less hook in the middle of the turn. So, overall turning smoothness will improve.

Another advantage you will get is our proven hydrophobic surface. This is like ceramic coating on your vehicle; water just shoots off in record time! This hydrophobic surface speeds up the water, which you should feel acceleration and gain some top speed. Who would of thought a steering nozzle could offer so much? We did, we test, we ride and we will find an advantage to offer you!

    This nozzle worked great on my 550SX and really woke up the steering!! I also paired it with the ProWatercraft 440/550 ride plate (which is also a 5-star product). Can’t say enough good things about this company!! Highly recommended products all around.
