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 engine.
Use the following information as a guide for
selecting a propeller that meets the operating
conditions of the boat and the outboard
motor.

ideal propeller for the boat is one that pro-
vides maximum performance in relation to
boat speed and fuel consumption.
