- Thrust balanced impeller design to extend engine life.
- Pump casing, diffusers and impellers manufactured from quality corrosion resistant marine grade aluminium for long life.
- Polyester coated pump casing, exterior and interior for added corrosion resistance.
- Patented floating impeller neckrings front and back. The front neckring helps improve pumping efficiency, the back neckring helps extend seal life and dramatically reduce engine wear.
- Self priming from 6m for more versatile installation options.
- Large priming and drain port with bayonet fit plugs Plugs have safety retention system, plus are available with 1/4" tapping to accept pressure gauges or drain cocks.
- Low-oil protection on all models - engines won’t start or run if oil level is inadequate, thus protecting your engine.
