Propeller selection

The performance of a boat and outboard
motor will be critically affected by the size
and type of propeller you choose. 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 motor.
Use the following information as a guide for
selecting a propeller that meets the operating
conditions of the boat and the outboard
motor.

Propeller size

The size of the propeller is indicated on the
propeller blade or outside of the propeller
boss.

Selection

When the engine speed is at the full throttle
operating range (5,000–6,000 r/min), the
ideal propeller for the boat is one that pro-
vides maximum performance in relation to
boat speed and fuel consumption.
