MJP 280 X Waterjet

The MJP 280 X is the smallest model in Marine Jet Power's X-Series of high-speed mixed-flow waterjets. Built around a duplex stainless steel mixed-flow pump, the X-Series is designed for speeds in excess of 50 knots, combining low weight, efficiency and corrosion resistance.

Key features

• Mixed-flow duplex stainless steel pump (the pump design has more than 18 million running hours)
• Hydrodynamically designed steering fin for responsiveness and steering efficiency
• Cast aluminium reversing bucket for shorter stopping distance and better manoeuvrability; narrow design reduces centre-to-centre spacing in multi-jet installations
• Interceptor integration: interceptor placement maximises stagnation pressure under the hull for extra lift; additional interceptors can be fitted on either side of the jet
• Optimised intake geometry for performance across the full speed range without compromising top speed
• All-inboard integrated hydraulic system with separated water and oil seals, eliminating external oil spill risk and compliant with clean-water regulatory requirements
