The information presented in this section is
intended as reference only. It is not possible
to provide complete instructions for every

WARNING
Overpowering a boat could cause se-
G
vere instability. Do not install an out-
board motor with more horsepower
than the maximum rating on the capac-
ity plate of the boat. If the boat does not
have a capacity plate, consult the boat
manufacturer.
Improper mounting of the outboard mo-
G
tor could result in hazardous condi-
tions such as poor handling, loss of
control, or fire hazards. For permanent-
ly mounted models, your dealer or oth-
er person experienced
rigging should mount the motor.

Mounting the outboard motor

The outboard motor should be mounted so
that the boat is well balanced. Otherwise, the
boat could be hard to steer. For single-en-
gine boats, mount the outboard motor on the
centerline (keel line) of the boat.
For twin engine boats, mount the outboard
motors equidistant from the centerline.
For triple engine boats, mount the center out-
board motor on the centerline (keel line), and
the port side and starboard side outboard
motors equidistant from the center outboard
motor.
Consult your Yamaha dealer or boat manu-
facturer for further information on determin-
ing the proper mounting location.

occur, which will reduce propulsion due to
excessive propeller slip, and the water in-
takes for the cooling system may not get ad-
equate water supply, which can cause
