Boat Operation Section 2
In some situations, you might want to change the pro-
pellers to give your boat slightly different performance
characteristics. Changes to your boat’s configuration,
such as additional equipment or adding bottom paint,
can affect the type and size of propeller required.
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 when viewed
from behind the boat. Counter-rotating propellers
have significant advantages for the boat operator.
They improve slow-speed maneuverability, help can-
cel engine torque, reduce steering effort, and help
carry extra weight.
If you are considering a propeller change, the type and
pitch should be discussed with your Brunswick Com-
mercial & Government Products supplier.
Refer to the engine operator’s manual for detailed
information about changing your propeller.

DANGER
To prevent the engine from starting acciden-
tally, turn the correct battery switch to the OFF
position before changing a propeller.
