WMC 450 Water JetThe WMC 450 water jet propulsion system has been designed for commercial use to give outstanding performance with boats up to 15 tonnes range for single jets. Proven construction features such as the glass reinforced plastic for the main static components are incorporated. This gives a light weight corrosion free main unit. The  pumps are of single stage mixed flow design which gives the most efficient performance for the flow rate and pressure to suit the vessel speed.
