POSITIONING DIAGRAMS OF SPURS CUTTER BLADE IN RELATION TO PROPELLER BLADES
DIRECTIONS
1) Looking aft, position edge of cutter blade slightly behind leading edge of propeller.
2) Cutter will cut in any position; however, it becomes more efficient when positioned correctly.
3) Positioned correctly, cutter will also be more effective when reverse cut is made.
ALL PROPELLERS ARE LOOKING AFT
CUTTER BLADE POSITIONING with reference to the PROPELLER BLADES Arrows on propeller blades below point to leading edge of propeller. VIEWED LOOKING AFT.
Position 2" + behind leading edge Position cutters as shown
Position 1/4" - 1/2" behind leading edge Position cutter blade approximately 1/4" to 1/2" behind leading edge of propeller blade; the other cutter blade then falls approximately midway between other propeller blades.
Position 2" behind leading edge Position cutter blades midway between propeller blades.
EXAMPLE OF WRONG CUTTER BLADE LOCATION
When the cutter blade is forward of propeller blade, the line will lay on top of cutter blade during this revolution of propeller. It will not be cut until next revolution.
