To ensure maximum efficiency, Spurs extensive sizes enable you to match closely propeller cutter body hub diameters.

3/16"/5mm is included in measurement for space for installation to allow water flow through bearing. Additional allowance for end float may be necessary. Coupling spacers available to increase shaft length if necessary to fit cutter.

Should your shaft size not be shown, Spurs can supply to suit any shaft diameter from 3/4" to 7". Large vessel cutters available above these sizes.
