Installation

The information presented in this section is
intended as reference only. It is not possible
to provide complete instructions for every
possible boat and motor combination. Prop-
er mounting depends in part on experience
and the specific boat and motor combination.

WARNING

EWM01590

●

Overpowering a boat could cause se-
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-
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 in proper

rigging should mount the motor.

EMU33481

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 en-
gine boats, mount the outboard motors equi-
distant from the centerline. Consult your
Yamaha dealer or boat manufacturer for fur-
ther information on determining the proper
mounting location.

EMU26931

Mounting height (boat bottom)

The mounting height of your outboard motor
affects its efficiency and reliability. If it is
mounted too high, propeller ventilation may
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
engine overheating. If the engine is mounted
too low, water resistance (drag) will in-
crease, thereby reducing engine efficiency
and performance.
Most commonly, outboard motor should be
mounted so that the anti-cavitation plate is in
alignment with the bottom of the boat. The
optimum mounting height of the outboard
