Remove all cotter pins from the pivot bar for blades and shaft. Salvage these
cotter pins if possible.
Pull pivot bar from the blades. It will be noticed on some propellers that one end
of the pivot bar is tapped for a bolt. Thread the bolt into this end of the pivot bar
and pull the bar by means of the bolt, on other types, the pivot bar may be
tapped out with a drift punch and hammer.
For both fixed and folding propellers:
Remove the shaft nut, which is counter sunk inside the propeller hub on folding
props and exposed on fixed props. To remove the shaft nut, a ½” square drive
handle with extension is required for folding props; a socket for fixed props.
To remove the propeller, leave the propeller retaining nut in place, but installed
about one or two turns loose from the fully tight position (to protect the threads).
The puller shaft should never bear directly on the end of the propeller shaft. As it
bears on the propeller retaining nut, a spacer of brass, aluminum or copper
should be used to protect the nut. The puller must be installed straight and
centered carefully so that its maximum effectiveness can be realized. Place the
claws of the prop puller behind the propeller hub and withdraw the propeller.
6.8
Installation of the Propeller
Ensure that the bore of the propeller is free from dirt and corrosion and that the
end of the shaft is clean. The keyways of the propeller and shaft must be free
from burrs. Place the propeller on the shaft with the keyways in the shaft and
propeller in line. The key should fit snugly at the sides with a 0.0111 minimum
clearance at the top. Do not force the key in as this may cause the propeller to
be forced off center. The propeller, locking nut and the cotter pin are then
assembled on the shaft. Check to ensure that the propeller is correctly aligned.
6.9
To Check Propeller Alignment
Clamp a piece of thin metal or wood on the propeller strut so that it just touches
one blade of the propeller. Rotate the shaft and propeller by hand. Any variance
in the track of the blades will be indicated by either a gap between the next blade
or that blade striking the indicator. If the propeller is found to be out of line, it
should be checked and balanced by a marine yard.
6.10 Exhaust System
The exhaust system utilizes a horizontal type muffler. In operation, the engine
water pump draws water through the engine intake port, circulates it through the
engine block then into the muffler. The water is mixed with the exhaust gases in
