The HydroJet Pro is the next generation precision steering system for jet boats.If you own a Jet Boat you understand the fantastic performance and superior advantages over a traditional propeller driven boat. You have probably figured out the challenging low speed handling characteristics as well. This is the reason we created the most advanced steering system available for jet boats. The new HydroJet Pro allows for effortless tracking and superior control when launching, trailering and reverse steering
Predictable
The HydroJet Pro provides the most accurate and precise steering available on the market today. Similar thrust vectoring products remain in a fixed position or retract at unpredictable and variable speeds. This compromises the feedback and performance of a jet boat. Our system is designed to precisely extend and retract relative to the throttle position, offering precision maneuverability at low speeds without compromising the high-speed characteristics.
Innovative
Why sacrifice speed, handling and performance?
Our revolutionary design provides more effective surface area, while reducing the overall drag of the system. Leave old standards behind and join us in pushing new limits on the water.
Engineered for Performance
Designed by an aerospace engineer and manufactured in the USA, the HydroJet Pro ensures the highest level of quality and hydrodynamic performance.
•
UV Resistant HDPE Marine Seaboard Fins – When designing the best, we had to use the best. That is why our HydroJet Pro system comes with the most durable materials out there, specially designed for marine applications. So don’t worry about the jaw dropping high-speed turns you will now be able to make. Our fins can handle it.
•
Direct Throttle Link System – For increased drag reduction and better performance at faster speeds, we have connected the nozzle shift rod directly to our HydroJet Pro system. High quality powder coated aircraft grade 5052 Aluminum parts provide a complete integration with your watercraft.
•
All Stainless Steel Hardware – We provide the durable hardware necessary to keep the HydroJet Pro system on your boat for years to come. Corrosion and oxidation free guaranteed!
Worry Free
Customer satisfaction is our number one priority. For this reason, we offer a worry free 3 year warranty on our system. If you have a problem, simply call or email us. We will take care of it.
The Engineering behind the HydroJet Pro
Steering enhancer devices are not new when it comes to jet boats. Jeff Walkowiak came up with a true innovative and patented steering enhancer design back in 2004. Since then, thousands of jet boat owners saw the perks of having such a system on their boats. As jet boat owners ourselves, we believed that it was time for an upgrade to the design. We wanted to truly improve the handling of the jet boat in an effortless and effective way.
With other systems steering characteristics changes with speed. We believe that removes part of the fluidity and type of control a pilot is looking for when buying a jet boat. Do not get us wrong, other systems will indeed improve handling, but we guarantee that none of them does it as seamlessly as we do. By fully integrating our system with the thrust lever, we can provide consistent handling independent of speed. The boat will always behave the same way, and you can expect constant reaction at the turn of your wheel.
Other steering systems started to feel too much like training wheels. It is great to learn on them, but we outgrow their need in a matter of hours. Our system, provides effective steering at the most crucial times, while at the same time letting you take control as you please. We do not take away the jet boat feel and handling characteristics, we simply make sure you have control when you most need it.
Here is our fins will help you turn
Unlike propelled boats, jet boats require constant thrust for steering. The lower the thrust, the harder is to control. Because there is no keel, the boat spins around its center of mass. The further away the nozzles are from it, the bigger the moment and the easier the boat will turn.
The effectiveness of our fins is also dependent on the type of the flow across them. There’s 2 types of regimes when it comes to fluid flow:
Laminar flow: where the motion of the particles of the fluid is very orderly with all particles moving in straight lines parallel. When an object is placed in laminar flow, it will disturb the particles in the flow. This will increase the pressure in front of said object and reduce it behind. In this case, the generated pressure difference will create a side force on our fins helping you turn your watercraft.
Turbulent flow: is a flow regime where the particles are already disturbed, and are constantly sustaining a chaotic property changes. In other words, because the flow is already disturbed, the effect an object can have on it is very small. The more intense the turbulent flow that our fins will encounter, the less they will help you turn.
The effectiveness of the side force created by the fins is dictated by the amount of perpendicular area to the incoming flow. The more of the fin area that faces the flow, the bigger the exerted force will be, increasing the turning moment of your boat.
Reverse
Because while on reverse the fins will always see linear flow, they provide maximum effectiveness. In this position, the fins work essentially as individual rudders, increasing the handling immensely while backing.
Idle
At very slow speeds, < 2 knots, the flow over the fins is also entirely linear, indicating a 100% effective area. Slow maneuvering will mostly occur at this range, and it is at this range that our fins perform at their best.
Forward
Between 3 and 6 knots, most of our fins are still observing linear flow. It is in this range that boats operate in marinas, around anchored boats and while navigating through multiple PWC’s.
Above 6 knots, our fins start losing its effectiveness due to the turbulent flow (drag bucket) directly behind the boat. The faster the boat moves the more turbulent the flow will be. For speeds higher than 10 knots the flow observed by the fins will be entirely turbulent and only the integrated thrust vectoring from your nozzle with turn your boat. At this stage, our system is completely out of the way, letting you experience the true jet boat feel without ancient training wheels.
