If the jam nut and prop nut are installed properly,
the propeller should not loosen. If you tighten both
nuts holding only the propeller blade, the nuts

HAFTS
The shaft coupling is the connecting point
between the shaft and the transmission/engine
(Figure 4.12.2). The alignment should be set at a
maximum of .005" (0.13 mm). A slight
misalignment will cause loss of power, excessive
wear, noise and vibration and should not be
tolerated. When checking for parallel coupling
faces (the proof of proper alignment), use a feeler
gauge not more than .003 to .005 of an inch thick
(0.08 – 0.13 mm).

With coupling faces brought together by hand –
not bolted – the feeler gauge should be tightly
gripped at all points around the edges of the
couplings. Next, hold the engine coupling flange
stationary and rotate the shaft coupling flange
90 degrees in either direction. The feeler gauge
should still be tightly gripped at all points around
the edges of the couplings.
