Boat Operation Section 2
Reducing propeller pitch and diameter will increase
acceleration and load carrying capability, with a slight
decrease in top speed. It will also increase the
engine’s full-throttle RPM at a rate of about 150 RPM
per inch of pitch change.
Increasing propeller pitch and diameter will
decrease acceleration and might increase top speed.
It will also decrease the engine’s full-throttle RPM at a
rate of about 150 RPM per inch of pitch change.
Your boat might be equipped with one engine that is
counter-rotating, which means that the port propeller
rotates in a counter-clockwise direction while in for-
ward gear when viewed from behind the boat. Coun-
ter-rotating propellers have significant advantages for
the boat operator. They improve slow-speed maneu-
verability, help cancel engine torque, reduce steering
effort, and help carry extra weight.
If you are considering a propeller change, the type,
pitch, and diameter should be discussed with an
authorized outboard servicing dealer.
Refer to the engine operator’s manual for detailed
information about propellers.
!
CAUTION
Mismatching propellers on a pair of counter-
rotating outboard engines could cause a loss of
directional control and could result in
catastrophic gearcase failure.
