BLUE FIT CHECK of PROPELLER:
The propellers are manufactured to close tolerances and therefore care
must be taken when handling and mounting. Prior to mounting it may be necessary to check the blue fit of the
propeller to guarantee a close fit to taper size. If the blue fit is unsatisfactory due to temperature differences, it
may be necessary to ream the propeller to suit. Therefore, please use the grinding paste supplied with the
propeller. It must be noted however that all blue fits will have been 70 to 80% of the taper length.
MOUNTING:
First slide the prop on the shaft without key. Mark the shaft with a grease-pen at the prop end. After
re-fitting the propeller with the key in the keyway on the shaft taper and correctly tightening the fastening nut very
strongly (torque-setting see page 10 ) the mark must no longer be visible. If not, the key is binding and the top or
the sides of the key must be filed down. Light must be shining through on the top of the key when looking into the
hub from astern. You may have to move your eye vertically to see it.
