ENOM00024-B

ENOW00006-0

Most boats are rated and certified in terms
of their maximum allowable horsepower, as
shown on the boat’s certification plate. Do
not equip your boat with an outboard motor
that exceeds this limit. If in doubt, contact
your dealer.
Do not operate the outboard motor until it
has been securely mounted on the boat in
accordance with the instructions below.

ENOW00009-0

z

Mounting the outboard motor without
following this manual can lead to unsafe
conditions such as poor maneuverability,
lack of control or fire.

z

Loose clamp screws and/or mounting
bolts can lead to the release or displace-
ment 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
(3.0 kgf) 13 ft-lb). Check the fasteners for
tightness from time to time.

z

Be sure to use outboard mounting fasten-
ers included in the outboard motor pack-
age or their equivalents in terms of size,
material, quality and strength.   Tighten
fasteners to the specified torque (30 Nm
(3.0 kgf) 13 ft-lb). Test cruise to check if
fasteners are tightened securely.

z

Outboard motor mounting must be per-
formed by trained service person(s) using
lift or hoist with sufficient capacity.

Keep the outboard motor in a vertical
position when mounting.

ENOM00025-B
