Specifications and requirements
17
specifications. The battery is an important
component necessary to obtain sure engine
starting and to maintain engine performance.
The engine may not start if the battery voltage
is too low.
For North America
It is necessary to meet only two of the three
specifications (CCA, MCA, and RC) in one of
the following combinations:
CCA/SAE and RC
MCA/ABYC and RC
For Oceania
It is necessary to meet the following specifi-
cations.
ECM01064
Do not use a battery that does not meet
the specified capacity. If a battery that
does not meet specifications is used,
the electric system could perform poor-
ly or be overloaded, causing electric
system damage.
Do not use a battery which exceeds the
maximum CCA rating. If the batteries
are used in parallel circuit, use new bat-
teries of the same type and make sure
that the total battery rating never ex-
ceeds the maximum CCA rating.

Mounting battery
Mount the battery holder securely in a dry,
well-ventilated, vibration-free location in the
boat. WARNING! Do not put flammable
items, or loose heavy or metal objects in
the same compartment as the battery.
Fire, explosion or sparks could result.

Battery cable
The battery cable size and length are critical.
Consult your Yamaha dealer about the bat-
tery cable size and length.

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.
