■ Transom Matching
Be sure that anti ventilation plate of
the outboard is below the water sur-
face when running with wide open
throttle.
In case the above condition cannot
be met due to the shape of your boat,
please consult your authorized dealer.
!
Overheating may occur if the Anti-ven-
tilation Plate is at a level higher than
the bottom of the boat, as a result of a
lack of cooling water.
If the height difference exceeds
10~30mm (0.4~1.2 in) engine power
performance is likely to be reduced
as a result of increased water resis-
tance to the gear case assembly.

■ Attaching the Clamp Bracket
After positioning the Clamp Bracket, fix it
with clamp screw then drill four holes in
the transom board, matching the holes
in the Clamp Bracket. Secure the engine
with the supplied bolts (M12×105mm)
and nuts, Be sure to use the washers.
Use the larger diameter washers inside
of the transom board and use the small
diameter washers outside of the clamp
bracket.
The mounting holes may be drilled be-
forehand by referring to the dimensional
drawing.
WARNING
!
● Mounting the outboard motor with-
out following this manual can lead
to unsafe conditions such as poor
maneuverability, going out of control
or fire disaster.
● Loose clamp screws and/or mount-
ing bolts can lead to the release or
displacement of the outboard motor,
possibly resulting in lost of control
and/or serious personal injury. Be
sure that fasteners are tightened
to the specified torque (30 Nm
(3.0kgf)13ft·lb). Check the fasteners
for tightness from time to time.
● Be sure to use outboard mounting
fasteners included in the outboard
motor package or their equivalents
in terms of size, material, quality and
strength.
Tighten fasteners to the specified
torque (30 Nm (3.0kgf)13ft·lb). Test
cruise to check if fasteners are tight-
ened securely.
● Outboard motor mounting must
be performed by trained service
person(s) using lift or hoist with suf-
ficient capacity.
