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.

Selection

operating range, the ideal propeller for the
boat is one that provides maximum perfor-
mance in relation to boat speed and fuel con-
sumption.
