ROPELLERS
Propellers should be free of nicks, excessive
pitting and any distortions that alter them from
their original design. Badly damaged propellers
should be replaced, but those that are chipped,
bent or merely knocked out of shape can be
reconditioned by your marine dealer.
When doing extensive cruising, it is advisable
to carry extra propellers aboard.

HARACTERISTICS
Propellers have two basic characteristics:
• Diameter
• Pitch
Diameter is that distance measured across the
propeller hub line from the outer edge of the 360°
that is made by the propeller’s blade during a single
rotation. Pitch is that distance in inches that a
propeller will travel if rotated one revolution without
any slippage.
For example, a propeller with a 12-inch pitch, when
rotated 360° would, theoretically, advance 12 inches
through the water. Actually, no propeller applied to
any boat is 100% efficient. No 12-inch pitch blade
