Honda 99 Outboard Owners Manual

							CONTROLS AND FEATURES 
The gearshift/throttle control lever controls 
engine speed and selects F (forward), N 
(neutral), or R (reverse) gears. 
Moving the control lever 30” from N (neutral) 
selects the gear, and further movement 
increases engine speed. 
A friction adjuster near the base of the control 
lever adjusts the operating resistance of the 
control lever (p .45). 
Less friction allows easier control lever 
movement. More friction helps to hold a steady 
throttle setting while cruising.

							CONTROLS AND FEATURES 
Steering Friction Lever 
STEERING FRlkTlON 
LEVER 
The steering friction lever adjusts steering 
resistance. 
Less friction allows the outboard motor to 
turn more easily. More friction helps to 
hold steady course while cruising or to 
prevent the outboard motor from 
swinging while trailering the boat. 
Tilt Lever 
The tilt lever enables the outboard motor 
to be raised for shallow water operation, 
beaching, launching, or mooring. 
To tilt, move the lever to the TILT 
position, then raise the outboard motor 
until the tilt mechanism engages at 30”, 
45”, or 7 1’ (p.48). 
INSTRUMENTS 
Fuel Gauge 
FUEL GAUGE 
A fuel gauge is built into the cap of the 
portable fuel tank.

							CONTROLS AND FEATURES 
INDICATORS 
Oil Pressure Indicator 
(R type) 
0-I type) 
OIL PRESSURE iNDICATOR LIGHT When the green light is lit, oil prcssurc 
is 
OK. 
If oil pressure becomes low, the green 
light will go off, and the engine protection 
system will limit engine speed. 
Remote controls are also equipped with a 
buzzer that sounds when the green light 
goes off. 
Low oil pressure indicates that the engine 
oil level is low, or that there is a problem 
with the engine lubrication system. Overheating Indicator 
CR type) 
If the engine overheats, the red light will 
come on, and the engine protection 
system will limit engine speed. 
Remote controls are also equipped with a 
buzzer that sounds when the red light 
comes on. 
Engine overheating may be the result of 
clogged water intakes. 
22  
						

							CONTROLS AND FEATURES 
Cooling System Indicator 
COOLING SYSTEM INDICATOR 
Water should flow from the cooling 
system indicator while the engine is 
running. This shows that water is 
circulating through the cooling system. 
If water stops flowing while the engine is 
running, that indicates a cooling system 
problem, such as clogged water intakes, 
which will cause engine overheating. 
OTHER FEATURES 
Overrev Limiter 
The engine is equipped with an overrev 
limiter to prevent the possibility of 
mechanical damage from excessive 
engine speed. 
The overrev limiter may be activated 
during operation, limiting engine speed, if 
the outboard motor is tilted excessively, 
or when ventilation occurs during a sharp 
turn. 
If the overrev limiter is activated, check 
the trim angle of the outboard motor. 
Automatic Choke (R type/HS 
type1 
The engine is equipped with an automatic 
choke so that the choke system operation 
does not need when starting the engine. 
Anodes 
ANODES 
The anodes are made of a sacrificial 
material that helps to protect the outboard 
motor from corrosion. 
There are two anodes on the gear case.

							CONTROLS AND FEATURES 
Portable Fuel Tank 
The portable fuel tank has a capacity of 
3.2 US gal ( I2 a) and has a fuel gauge 
built into the cap. Fuel Cap Veut Knob 
VENT KNOB 
SE 
The cap is provided with a vent knob to 
seal the portable fuel tank for carrying it to 
and from the boat. Open the vent knob 2 or 
3 turns before starting the engine (p.34). Fuel Priming Bulb 
OUTLET END 
A priming bulb is built into the fuel hose 
that connects the fuel tank to the outboard 
motor. 
Before starting the engine, squeeze the 
priming bulb until it feels firm. This will 
ensure that fuel is supplied to the engine 
(P.35).

							INSTALLATION 
Correct and secure installation is essential 
for safe boating and good performance. 
Follow the installation instructions 
provided in this manual. 
POWER REQUIREMENTS 
Before installation, check to be sure that 
the outboard motor does not exceed the 
recommended maximum horsepower for 
the boat on which it is to be installed. 
Refer to the boat’s certification plate for 
recommended maximum horsepower. If 
the certification plate information is not 
available, contact the boat dealer or 
manufacturer. 
For most applications, the outboard motor 
should have a horsepower rating which 
provides 80% of the maximum 
recommended horsepower for the boat. 
BOAT TRANSOM 
REQUIREMENTS 
Honda BF8D/BFPgD/BF9.9D and 
BFP9.9D outboard motors can be 
installed on a boat transom having a 
thickness range of 1.3 - 2.2 inches (35 - 
57 mm). 
INSTALLATION POSITION 
CENTERLINE 
Install the outboard motor on the center of 
the boat transom. The anticavitation plate of the outboard 
motor should be 0 - 2.0 inches below the 
bottom of the boat. With the boat in the 
water and loaded, the anticavitation plate 
should be about 3.9 inches below the 
surface of the water.

							INSTALLATION 
If the outboard motor is installed too low, 
the boat will squat and be hard to plane, it 
will tend to porpoise, and high-speed 
stability will be reduced. 
lfthe outboard motor is installed too high, 
that will cause ventilation. 
Optimum installation height varies with 
boat type and bottom shape. Contact the 
boat manufacturer for any special 
recommendations that arc unique to a 
specific model of boat. 
If the transom needs to bc modified to 
accommodate the outboard motor, contact 
the boat manufacturer and follow their 
recommendations for corrective action. ATTACHMElNT

Attach the stem bracket to the boat 
transom by tightening the clamp screws. 
Attach a rope from the boat to the hole in 
the stem bracket. This will help to prevent 
accidental loss of the outboard motor. 
You may further secure the outboard 
motor by bolting the stem bracket to the 
boat transom. Use the optional mounting 
bolt and nut kit or other good quality 
stainless steel bolts, nuts, and washers. 
Apply silicone sealant to the bolt holes.

							INSTALLATION 
TRANSOM ANGLE 
ADJUSTMENT 
Use the transom angle adjusting rod (p. 
33) to adjust the angle of the outboard 
motor so the propeller is perpendicular to 
the surface of the water. 
BATTERY CONNECTIONS 
BATTERY 
Honda BF8D/BFP8D/BF9.9D and 
BFP9.9D outboard motors produce a 12- 
volt, 12-ampere battery-charging current 
and are equipped for connection to a 12- 
volt battery. The battery-charging circuit 
is protected by a 20-ampere fuse located 
in the engine compartment. 
The outboard motor’s 12-volt output is 
intended for battery charging only. Lights 
and electrical accessories for the boat 
should be connected to the battery. The battery should be kept in a corrosion- 
resistant battery box that is securely 
mounted in a location away from the fuel 
tank and protected from water and direct 
sunlight. 
Types With Electric Starter 
These types are equipped with battery 
cables. The positive (+) cable has a red 
band at the battery connector. The 
negative (-) cable has a black band at the 
battery connector. 
For electric starter operation, use a 12- 
volt battery with an ampere-hour rating of 
at least 35 Ah. 
Types Without Electric Starter 
These types are equipped with a 12-volt 
dc battery-charging receptacle which can 
be wired to a 12-volt battery to power 
lights and electrical accessories for the 
boat.

(models without electric starter) 
- TO ACCESSORIES 
To prepare the outboard motor for 
connection to a battery, pull the cover out 
of the DC receptacle, connect your battery 
charging wires to the receptacle. Attach 
the connected DC receptacle on the holder 
on the tiller arm. 
The receptacle is provided with a cover, 
which should be attached when the

Connect the positive (+) battery cable to 
the positive (+) battery terminal, then 
connect the negative (-) battery cable to 
the negative (-) battery terminal. 
The negative (-) battery cable should 
always be removed from the battery when 
connecting or disconnecting the positive 
(+) battery cable, so tools cannot cause a 
short circuit if they touch a grounded part 
while being used on the positive (+) 
battery terminal fitting.
