Multiple batteries
To connect multiple batteries, such as for
multiple engine configurations or for an ac-
cessory battery, consult your Yamaha dealer
about battery selection and correct wiring.

Propeller selection
Next to selecting an outboard motor, select-
ing the right propeller is one of the most im-
portant purchasing decisions a boater can
make. The type, size, and design of your pro-
peller have a direct impact on acceleration,
top speed, fuel economy, and even engine
life. Yamaha designs and manufactures pro-
pellers for every Yamaha outboard motor and
every application.
Your Yamaha dealer can help you select the
right propeller for your boating needs. Select
a propeller that will allow the engine to reach
the middle or upper half of the operating
range at full throttle with the maximum boat-
load. Generally, select a larger pitch propeller
for a smaller operating load and a smaller
pitch propeller for a heavier load. If you carry
loads that vary widely, select the propeller
that lets the engine run in the proper range for
your maximum load but remember that you
may need to reduce your throttle setting to
stay within the recommended engine speed
range when carrying lighter loads.
Yamaha recommends to use a propeller suit-
able for the "Shift Dampener System (SDS)".
For further information, consult your Yamaha
dealer.
To check the propeller, see page 80.

Counter rotation models
Standard outboard motors rotate clockwise.
Counter rotation models rotate counterclock-
wise and are typically used in multiple motor
setups.
On counter rotation models, be sure to use a
propeller intended for counterclockwise rota-
tion. These propellers are identified with the
letter "L" after the size indication on the pro-
peller. WARNING! Never use a standard
propeller with a counter rotation motor, or
a counter rotation propeller with a stan-
dard motor. Otherwise the boat could go
