■ Transom Height
Install the engine with the Anti-ventilation
Plate at a level 10~30mm(0.4~1.2in.)
below the bottom of the boat.
■ Transom Matching
Be sure that anti ventilation plate of the
outboard is below the water surface
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-
ventilation Plate is at a level higher
than the bottom of the boat, as a result
of a lack of cooling water.

■ 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

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.

● Mounting the outboard motor
without following this manual can
lead to unsafe conditions such as
poor maneuverability, going out of
control or fire disaster.
● Loose clamp screws and/or
mounting 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
tightened securely.
● Outboard motor mounting must
be performed by trained service
person(s) using lift or hoist with
sufficient capacity.
