look from stern to stem. If the shaft rotates clockwise, the rotation is right-handed; 
by contrast, if it rotates counterclockwise, the rotation is left-handed). In order to 
change rotation of the MAX PROP

®

  WHISPER,  from  right-hand  rotation  to  left-hand 

rotation or vice versa, operate as follows referring to fig. 7.

• Unscrew the screws locking the zinc, and remove the zinc.

• Unscrew the screws locking the nut, and remove the nut.

•  At the aft edge of the hub there is a Seeger ring: remove it.

• Remove the transmission ring on which the zinc is fixed (zinc-holding ring).

• Once the zinc-holding ring has been pulled out, you can see there is an engraving on 

one tooth of the hub (aft side), and two teeth of the zinc-holding ring are marked 
with “L” (left) and “R” (Right), respectively.

•  If you reassemble the zinc-holding ring, placing the tooth “R” at the tooth of the hub 

where the engraving is stamped, you will have a right-hand propeller, if you rather insert 
the ring placing the tooth “L” at the tooth of the hub where the engraving is stamped, 
you will have a left-hand propeller (see fig. 7).

•  Insert the Seeger ring in its seat.

• Screw the nut and lock it with the nut-locking screws.

• Put back the zinc, and fasten it with the three special screws.
