1. COMMON MODEL INFORMATION
MOTOR SELECTION
Secure and correct outboard motor set-up is
essential for safe boating and good performance.
Follow the installation instructions provided in this
guide.
I NOTICE I
Do not use an air impact tool to tighten or loosen
the transom bolts. Using an air impact tool
to tighten
or loosen the transom bolts can generate enough
heat
to damage the bolt threads. The air impact tool
can also produce enough tightening torque to
damage the boat transom.
Before installation, be sure the outboard motor does
not exceed the recommended maximum
horsepower for the boat. Refer to the boat's
certification plate for recommended maximum
horsepower. For most applications, the outboard
motor should provide 80% of the recommended
maximum horsepower for the boat. If the
certification plate information is not available,
contact the boat dealer or manufacturer.
Refer to the dimensional drawings in the
appropriate
Honda Marine Shop Manual to be sure
there is nothing on the boat that will interfere with
outboard motor tilt-up and steering.
On a dual motor installation when the minimum
distance between motors is used, the engine cover
of one motor June interfere with the adjacent motor
if only one motor is tilted up when the boat is
steered full right or full left.
1 NOTICE I
Do not tilt one motor up when the boat is steered full
right or full lee, or the engine cover June be
damaged.

BOAT TRANSOM BOAT TRANSOM
Install the outboard on the center of the transom
securely, and be sure the boat is well-balanced.
PLATE
As a general rule, the outboard should be mounted
so the anti-ventilation plate is parallel to and on the
same plane as the boat bottom or slightly higher.
If the boat transom angle is less than
8" (4" on
BF8D/9.9D, BF15D/BF20D and BF25A/30A; 12" on
BF200A/225A), the anti-ventilation plate will not be
parallel to the boat bottom when trimmed to the
lowest hole.
5 in.
With the boat loaded and unmoving, and the
outboard perpendicular to the water, ensure a
minimum 5 in. clearance exists from the idle
exhaust ports to the water level.
Refer to the boat specifications for details.
