Propeller selection
The performance of a boat and outboard
motor will be critically affected by the size
and type of propeller that is used. Propellers
greatly affect boat speed, acceleration,
engine life, fuel economy, and even boating
and steering capabilities. An incorrect choice
could adversely affect performance and
could also seriously damage the engine.
Use the following information as a guide for
selecting a propeller that meets the operating
conditions of the boat and outboard motor.
Propeller size
The size of the propeller is indicated on a
propeller blade, on the propeller boss end,
and on the side of the propeller boss.
a
Propeller diameter (in inches)
b
Propeller pitch (in inches)
c
Propeller type (propeller mark)
Selection
When the engine speed is at the full throttle
operating range, the ideal propeller for the
boat is one that provides maximum perfor-
mance in relation to boat speed and fuel con-
sumption.
