Battery requirements

Specifications of Battery
Use a fully charged battery that meets the fol-
lowing specifications. The engine cannot be
started if battery voltage is too low.
For North America
For Oceania
ECM01063
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-
ceed the maximum CCA rating.
EMU36291
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.

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 83.
