m           Honda Outboard motors are designed to give safe dependable
service if operated   according  to instructions.    Read-and  understand  the
Owner's   `Manual before operating    the Outboard     Motor. Failure to do so
could result in personal injury or equipment      damage.

To ensure     safe operation-

    Understand       the operation       of all controls,   and know how to stop the
    engine quickly-        READ THlS OWNER'S MANUAL                  CAREFULLY.
    Do not exceed the boat manufacturer's                power recommendation,      and be
    sure the outboard        motor is properly mounted.
    Never permit anyone to operate the outboard                   motor without      proper
    Stop the engine immediately             if anyone falls overboard.
    Do not run the motor while the boat is near anyone in the water.
    Exhaust      contains    poisonous       carbon monoxide      which can cause un-
    consciousness        and may lead to death. Never run the outboard in a clos-
    ed garage or confined          area.
    Gasoline is extremely         flammable      and is explosive     under certain condi-
    tions. Refuel in a well-ventilated           area with the engine stopped.
    Do not smoke or allow flames or sparks where the engine is refueled or
    where gasoline is stored.
    Do not overfill the fuel tank. After refueling make sure that the fuel tank
    cap is closed properly and securely.
    Be careful not to spill any fuel while refueling.           Spilled fuel or fuel vapor
    may ignite. If any fuel is spilled, make sure that the area is dry before
    starting the engine.
    Do not remove any guards, labels, shields, covers or safety devices;
    they are installed for your safety.

It is your responsibility to choose a
boat suitable for the engine (2 horse-

manufacturer's    power recommenda-
tion. Damage and injury may result.
Two shaft lengths are available     for
the BF2A, either long or short, to

1. Installation   Position

Install at the stern at the center line
of the boat.

2. Installation   Height

For proper propellei depth and engine
cooling, the boat's transom height
must match         the motor's    shaft
length. The short shaft motor re-
quires a transom height of about 15
in. The long shaft motor requires a
transom of height about 20 in. Once
the boat is in the water and loaded,
check proper motor depth by looking
at the anti-cavitation plate: with the
motor not running, the plate should                              CAVITATION
be about 100 mm (4 in.) below the
surface of the water.
During operation, check to be sure the anti-cavitation plate remains under
water at all times and that water flows from the water check hole.
Excessive or imbalanced loading will affect the motor's water depth.
Loading too far forward will raise the motor out df the water, reducing
engine cooling. Loading too much or too far rearward will push the motor
deeper, reducing performance.

CAUTION:   Insufficient water      supply   (anti-cavitation plate   out of the
water) may cause overheating      that will damage the outboard      motor.

3. Motor   Attachment
Attach the stern bracket to the transom and tighten the clamp screws.
l While operating     the boat, check
  the tightness  of the clamp screws
l Tie a rope through the hole in the
  stern bracket and secure the other
  end of the rope to the bo,at. This
  will prevent accidental   loss of the

1. Engine   Oil Level

l Engine oil is a major factor affecting    engine performance     and service
  life. Nondetergent   and low quality oils are not recommended,      because
  they have inadequate     lubricating properties.
l Running    the engine with insufficient       oil can cause serious engine

Use Honda 4-stroke oil or an equi-
valent     high detergent,     premium
quality motor oil certified to meet or
exceed U.S. automobile         manufac-
turers'     requirements    for Service
Classification     SF CC/CD or SG.
Motor oils classified SF CC/CD or SG
will show this designation         on the
container.                                 -20

area. SF CC/CD or SG low-30             is
 recommended          for general,    all-
temperature use.
 1. Position the outboard motor vertically, and check the oil level in the oil
    level inspection window.
 2. If the oil level is down toward the lower level mark on the window, fill
    up to the 0.4 e (0.42 U.S. qt.) mark on the dipstick.

                                     LOWER LEVEL 0.2 P(0.21 U.S. qt.)
2. Fuel Level
Remove the filler cap and check the fuel level. Refill the tank if the fuel
level is low.
NOTE: Open the vent knob before removing the fuel filler cap. When the
vent knob is firmly closed, the cap will be difficult'to    remove.
Your engine R  `s +esigned     to use any gasoline that has a pump oc-
tane number (-        ) of 86 or higher, or that has a research octane number
of 91 or higher.2Gasoline pumps at service stations normally display the
pump octane number.
We recommend that you use unleaded fuel because it produces fewer
engine and spark plug deposits and extends the life of exhaust system
Never use stale or contaminated           gasoline or an oil/gasoline mixture. Avoid
getting dirt, dust or water in the        fuel tank. Use of a lower octane gasoline
can cause persistent "pinging"            or heavy "spark knock" (a metallic rapp-
ing noise) which, if severe, can          lead to engine damage.
CAUTION:      If "spark   knock" or "pinging"     occurs at a steady engine
speed under normal load, change brands of gasoline.         If spark knock or
pinging persists, consult your authorized     Honda dealer. Failure to do so is
considered    misuse,   and damage caused by misuse is not covered          by
Honda's Limited Warranty.
Occasionally you may experience light spark knock while operating under
heavy loads. This is no cause for concern, it simply means your engine is
operating efficiently.

                   FUEL FILLER CAP                         FUEL TANK

After refueling,     be sure to tighten     the fuel tank cap firmly.
w             Gasoline     is extremely    flammable   and is explosive   under   certain
l   Refuel in a well-ventilated     area with the engine stopped. Do not smoke
    or allow flames or sparks in the area where the engine is refueled or
    where gasoline is stored.
l   Do not overfill the tank (there should be no fuel in the filler neck). After
    refueling,  make sure the tank cap is closed properly and securely.
l   Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may
    ignite. If any fuel is spilled, make sure the area is dry before starting the
l   Avoid repeated or prolonged         contact with skin or breathing  of vapor.
If you decide to use a gasoline containing alcohol (gasohol), be sure its oc-
tane rating is at least as high as that recommended by Honda. There are
two types of "gasohol":    one containing ethanol, and the other containing
methanol. Do not use gasohol that contains more than 10% ethanol. Do
not use gasoline containing methanol (methyl or wood alcohol) that does
not also contain cosolvents and corrosion inhibitors for methanol. Never
use gasoline containing more than 5% methanol, even if it has cosolvents
and corrosion inhibitors.
l Fuel system damage or engine performance problems resulting from the
  use of fuels that contain alcohol is not covered under the warranty.
  Honda cannot endorse the use of fuels containing methanol since
  evidence of their suitability is as yet incomplete.
l Before buying fuel from an unfamiliar station, try to find out if the fuel
  contains alcohol; if it does, confirm the type and percentage of alcohol
  used. If you notice any undesirable operating symptoms while using a
  gasoline that contains alcohol, or one that you think contains alcohol,
  switch to a gasoline that you know does not contain alcohol.

3. Other   Checks

Check   the following   items.
@ Propeller, shear pin and cotter pin. Check for looseness or damage.
@ Steering handle. Check for impaired operation.
@ Stern bracket. Check for damage.
@Tool kit. Check for missing spare parts and tools (page 27).
@ Anode metal. Check for looseness, damage or excessive corrosion.

The anode metal helps to protect the outboard motor from corrosion
damage; it must be exposed directly to the water whenever the motor is in
use. Replace the anode metal when it has been reduced to approximately
one half of its original size.

CAUTION:'    The possibility  of corrosion damage   increased   if the anode
metal is painted over or allowed to deteriorate.

                                    5. STARTING        THE ENGINE

CAUTION:     To prevent damage to the outboard from   overheating,   never
run the engine with the propeller out of the water.

1. Open the fuel cap vent knob 2 to 3 turns.

2. To reverse direction,     turn the motor 180,   and then pivot the steering
   handle as shown.

CAUTION:    When operating    in reverse, proceed with     caution   to avoid   hit-
ting any under water obstruction     with the propeller.
4. Tilting   the Motor

Tilt the motor to prevent the propeller and gear case from hitting bottom
when the boat is beached or stopped in shallow water.

1. Stop the engine and turn the fuel valve lever off.
2. Close the fuel cap vent knob.
3. With the motor in the forward position, raise the motor using the carry-
   ing handle. The spring-loaded tilt lever will automatically   move into
   position and hold the motor when it reaches approximately 75'.
4. Adjust the steering friction bolt to keep the motor from moving.

CAUTION:     If the motor is tilted in the reverse position, crankcase oil will
enter the cylinder   and may cause difficult      starting   or may prevent the
engine   from being cranked.       If this occurs,      refer to the TROUBLE-
SHOOTING     section. page 36.

5. To return the motor to the normal RUN position, hold the motor by the

CAUTION:    Do not transport the motor in the tilted      position;   it may drop
suddenly causing damage to the boat or the motor.

CAUTION:      To avoid damaging    the motor, use the utmost care when
mooring the boat, especially  when its motor is tilted up. Don't allow the
motor to strike against the pier or other boats.


CAUTION:     To avoid damaging   the motor,   never use it as a handle   for lif-
ting or moving the boat.

l   High altitude   operation

At high altitude, the standard carburetor air-fuel mixture will be excessive-
ly rich. Performance will decrease, and fuel consumption will increase.
High altitude performance can be improved by installing a smaller diameter
main fuel jet in the carburetor and readjusting the pilot screw. If you
always operate the outboard motor at altitudes higher than 6,000 feet
above sea level, have your authorized Honda Outboard Motor dealer per-
form these carburetor modifications.

Even with suitable caburetor jetting, engine horsepower will decrease ap-
proximately 3.5% for each 1,000 foot increase in altitude. The effect of
altitude on horsepower will be greater than this if no carburetor modifica-
tion is made.

CAUTION:      Operation of the outboard motor at an altitude lower than the
carburetor  is jetted for may result in reduced performance,      overheating,
and serious engine damage caused by an excessively      lean air/fuel mixture.

    CAUTION:       Used motor oil may cause skin cancer if repeatedly   left in
    contact    with the skin for prolonged periods. Although  this is unlikely
    unless you handle used oil on a daily basis, it is still advisable        to
    thoroughly     wash your hands with soap and water as soon as possible
    after handling used oil.

NOTE: Please dispose of used motor oil in a manner that is compatible
with the environment. We suggest you take it in a sealed container to your
local service station for reclamation. Do not throw it in the trash or pour it
on the ground.

3. Gear Oil Check/Change

Oil Level Check
Check the oil level when the engine is in the vertical position. Remove the
level bolt and see if oil flows out. If no oil comes out, fill through the drain
bolt hole until the oil starts to flow out through the level bolt hole. If there
is water in the oil, the water will flow out first when the drain bolt is
removed, or the oil will be a milky color.

Oil Change
Remove the level bolt and drain bolt to drain the oil. Inject oil through the
drain bolt hole until it starts flowing out through the level bolt hole.
Reinstall and tighten the level bolt and drain bolt securely.

CAUTION:      If water is detected in the oil, the unit should   be inspected   by
an authorized    Honda outboard    motor dealer.

Recommended         Oil: API standard (GL-4 or GL-5)
                         SAE 90 outboard motor gear oil
Oil capacity:            0.059 (0.053 U.S. qt.)



4. Starter      Rope Check

Check the starter rope every 6 months or after every 100 hours of out-
board motor operation. Replace the rope if it is frayed.
5. Spark   Plug Service

1.  Remove the ,engine cover.
2.  Remove the spark plug cap.
3. Use the wrench supplied in the tool kit to remove the spark plug.
4. Visually inspect the spark plug. Discard it if the insulator is cracked or
5. Measure the plug gap with a feeler gauge.
   The gap should be 0.7-0.8          mm (0.028-0.031         in). Correct as
   necessary by bending the side electrode.
6. Check that the spark plug washer is in good condition, and thread the
   spark plug in by hand to prevent cross-threading.
7. After the spark plug is seated, tighten with socket wrench to compress
   the washer.

NOTE: If installing a new spark plug, tighten l/2 turn after the spark plug
seats to compress the washer. If reinstalling a used spark plug, tighten
l/8- l/4 turn after the spark plug seats to compress the washer.

8. Reinstall the engine cover.

l The spark plug must be securely tightened.     An improperly  tightened
  plug can become very hot and may cause engine damage.
l Use only the recommended   spark plug or equivalent. Spark plugs which
  have an improper heat range may cause engine damage.

After each use in salt water or dirty water, thoroughly    clean and flush the
outboard motor.

1. Wash the outside of the outboard motor.with clean, fresh water.
2. Remove the propeller.
3. Stand the motor in a suitable container of water. The water level must
   be at least 4 inches above the anti-cavitation  plate.
4. Start the engine and run it slowly for at least 5 minutes.

                                                ANTI-CAVITATION   PLATE

l   For safety, the propeller must be removed.
l   Be sure the outboard     motor is securely mounted, and do not leave it
    unattended   while running.
l   Keep children and pets away from the area, and stay clear of moving
    parts during this procedure.

CAUTION:    Running the engine without    water can cause serious engine
damage due to overheating.     Be sure that water flows from the water
check hole while the engine is running. If not, stop the engine and deter-
mine the cause of the problem.

 7. Lubrication

 Wipe the outside of the engine with a cloth dipped in clean oil. Apply
 marine anti-corrosion grease to the following areas:

damage when the propeller strikes an obstruction.

1.   Remove the cotter pin and the propeller.
2.   Remove the broken shear pin and replace it with a new one.
3.   Install the propeller.
4.   Install a new cotter pin, and spread the ends as shown                   in the

CAUTION:      When replacing    the shear pin, be careful       not to drop the pro-
peller into the water.

Precautions   concerning   the propeller

The propeller rotates at high speed when the boat is moving. Before set-
ting off, therefore, check the propeller blades for damage or deformation,
and if there are any abnormalities replace the propeller. Carry a spare pro-
peller in case of an unforeseen accident on the water.
If a spare propeller is not available and an accident does occur, return to
shore carefully while running the engine at low speed.

9. Servicing    a Submerged          Motor

A submerged motor must be serviced immediately after it is recovered
from the water in order to minimize corrosion.
If there is a Honda outboard motor dealership nearby, take the motor im-
mediately to the dealer. If you are far from a dealership, proceed as
1. Remove the engine cover, and rinse the motor with fresh water to
    remove salt water, sand, mud, etc.
2. Drain the fuel tank into a suitable container.
3. Loosen the carburetor drain screw (page 351, drain the contents of the
    carburetor into a suitable container, then retighten the drain screw.
4. Change the engine oil (page 28). If there was water in the engine
    crankcase, or the used engine oil showed signs of water contamination,
    then a second engine oil change should be performed after running the
    engine for l/2 hour.
5. Remove      the   spark   plug.   While   pressing   the engine   stop   button;   pull the
     recoil starter several times to completely          expel water from the cylinder.

l When cranking    the engine with an open ignition       circuit (spark plug
  removed from the ignition circuit), keep the engine stop button depress-
  ed to prevent electrical damage to the ignition system.
l If the motor was running when it submerged,      there may be mechanical
  damage, such as a bent connecting    rod. If the engine binds when crank-
  ed, do not attempt to run the motor until it has been repaired.

6. Pour a teaspoon of engine oil into the spark plug hole, then pull the
   recoil starter several times to lubricate the inside of the cylinder.
   Reinstall the spark plug.
7. Attempt to start the engine. If the engine fails to start, remove the
   spark plug, clean and dry the electrode, then reinstall the spark plug and
   attempt to start the engine again. If the engine starts, and no
   mechanical damage is evident, continue to run the engine for l/2 hour
   or longer (be sure the water level is at least 4 inches above the anti-
   cavitation plate).
8. As soon as possible, take the motor to a Honda outboard motor dealer
   for inspection and service.

1. Drain the water from the extension case.
   While depressing the engine stop button to prevent starting, pull the
   starter rope several times to expel the water from the extension case.

l Do not rest the motor on its side until the water has been expelled from
  the extension   case, otherwise water will seep into the exhaust system.
l In cold weather, the water must be expelled from the extension case to
  prevent ice from forming in the water pump and water tube.

2. Drain the fuel
   1. Turn the fuel valve lever off.
   2. Remove the fuel filler cap and drain the gasoline from the fuel tank in-
      to a suitable container.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
