HJ waterjets are generally suitable for 6-20m craft, depending on the number of waterjets used, hull displacement, and the vessel’s application.Ĭontrol systems range from fully manual, to manual hydraulic to the electronic blue ARROW control system. HamiltonJet’s smaller range of waterjets – 8 models ranging from 200mm to 400mm diameter impellers. This will drop RPM and increase performance.The current HamiltonJet waterjet range includes models for power inputs from 260 to 900kW (350hp – 1200hp), with integrated features such as intake and transition duct for easy installation, as well as steering and reverse components. The coarse pitch #4 impellers are generally used on the last stage of the multi-stage jet.įor the best performance upgrade to an older three stage jet, change the third impeller (back impeller) to a #4, and replace the nozzle with a 92 mm Pozzi nozzle. The big block power plants (8.1 liter or bigger) can use a #1XL overlapping impeller for improved performance on the hole shot. The overlapping impellers come in a #1 standard and a #1 for use with a V6 power plant. The remaining four impellers come in four different pitch sizes: #2 is a 22-degree pitch, #3 is a 23-degree pitch, #4 is a 24-degree pitch, and #5 is a 19-degree pitch impeller. These impellers are designated #1 on multi-stage jets.

There are three different 'overlap' impellers that are used on the first stage of multi-stage jets. These impellers come in various pitches and styles. These impellers are open face, stainless steel axial flow impellers that are nicely made and very rugged.
