Mounting battery

Mount the battery holder securely in a dry,
well-ventilated, vibration-free location in the

Multiple batteries

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

Propeller selection

Next to selecting an outboard motor, selecting
the right propeller is one of the most important
purchasing decisions a boater can make. The
type, size, and design of your propeller have
a direct impact on acceleration, top speed,
fuel economy, and even engine life. Yamaha
designs and manufactures propellers for ev-
ery Yamaha outboard motor and every appli-
cation.
Your outboard motor came with a Yamaha
propeller selected to perform well over a
range of applications, but there may be uses
where a different propeller would be more ap-
propriate.
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
22
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.
To check the propeller, see page 98.

Counter rotation models

Standard outboard motors rotate clockwise.
Counter rotation models rotate counterclock-
wise. Counter rotation models are typically
used in multiple motor setups and are marked
with an "L" on the gear case above the anti-
ventilation plate.
