PROPELLER DISASSEMBLY
In order to remove the propeller you must first remove the zinc and the nut-locking
screws; then fasten a perforated washer, supplied only on request, on the zinc-holding
ring by means of five threaded grub screws (fig. 8). Screw the five threaded grub screws
(long enough and provided with five nuts) into the five threaded holes obtained in the
zinc-holding ring, making sure that all five threaded grub screws are tightened to the
bottom of their own threaded hole. Then lean all five nuts on the perforated disc which
acts as extractor (see fig. 8). Start unscrewing very smoothly the propeller-locking nut,
which will press against the washer (fig. 8) and check that all five extraction screws
work together with the same load to extract the propeller. Slowly unscrew the nut
and be careful not to overload the screws to prevent them from breaking. When, due
to nut unscrewing, stress is applied to all 5 screws, it may be helpful to knock lightly
on the propeller body with a plastic mallet. Said knocks will detach the propeller hub
from the propeller shaft.
