STERN-DRIVE OPERATION

22 ZT370 Operation Manual

PROPELLER SELECTION

The propeller converts the engine’s power

into the thrust needed to propel the vessel.

Careful selection of your propeller is very

important to proper vessel operation.

Propellers are identified by two numbers,

such as 15.75  20 left-hand and stainless

steel propeller. In the number sequence,

the first number is the diameter of the

propeller and the second is the pitch.

Left-hand is counterclockwise rotation for

front propeller. Right-hand is clockwise

rotation for rear propeller.

Pitch is the angle of the blades expressed

in the theoretical distance a propeller

travels in each revolution. If for example

the pitch is 20, each revolution of the

propeller pushes the vessel 20 in. through

the water. A 28 pitch is considered “higher”

pitched and a 20 pitch propeller is

considered “lower” pitched. A smaller pitch

propeller should be selected for water

skiing or for heavy loads.

Keep these guidelines in mind when

selecting a propeller:

• Your Yanmar Marine dealer or distributor

is most qualified to help you select a

propeller.

NOTICE

Never attempt to change propellers until

after determining the average load and

individual requirements.

• Engine rpm must be within the

recommended operating range. Refer to

the Engine Operator’s Manual.

WARNING

To prevent accidental start-up,

complete the following before installing

or removing the propeller:

• Put the remote control to the

NEUTRAL position.

• Put the main switch to the OFF

position and remove the key.

WARNING

Never use your hand to hold the

propeller when loosening the nut. Put a

wood block between the antiventilation

plate and the propeller blade to prevent

the propeller from turning.

Problems associated with propellers

include ventilation, cavitation and blow-out.

These problems have similar symptoms

and are best diagnosed by an expert. If a

propeller related problem develops,

consult your Yanmar Marine dealer or

distributor.
