Quite simply, an engine or motor spins the driveshaft of the jet, attached to the drive shaft is an IMPELLER. Water flows in through the opening in the bottom of the hull, and the impeller increases the velocity of the water and it exits through the rear of the jet. This water flow leaving the rear of the jet pushes the boat through the water.
Alamarin-Jets are MIXED FLOW waterjets giving both AXIAL FLOW and CENTRIFUGUAL FLOW due to the tapered impeller design and also conical housing.
Alamarin-Jets have many unique features such as CONICAL HOUSINGS, COMBI-FRAME TECHNOLOGY, GREASE LUBRICATED REAR BEARINGS plus much more.
LONG TAIL installation is very useful when the need to move an engine further aft is required. It may be that deck space needs to be maximised or that weight distribution needs to be optimised, or that simply engine room space is minimal. With the traditional waterjet installation method this is very difficult to do. Sometimes though is not possible to have a long tail installation due to overall vessel length constrictions for example, hence the reason Alamarin-Jet developed the patented COMBI-FRAME TECHNOLOGY.
