Carburetor
Power nozzle
The power nozzle is activated when the engine is operating at high speeds. To reduce the fuel consumption rate and the pollution of the exhaust gases, the carburetors of the F60 are set lean. Therefore, the air-fuel mixture becomes lean at high engine speeds, when greater output is needed. The
power nozzle supplies a richer fuel mixture at high engine speed to realize the optimal air-fuel ratio
to produce output.

Propeller selection
1
The performance of a boat and outboard
motor will be critically affected by the size
and type of propeller you choose. Propellers
greatly affect boat speed, acceleration,
engine life, fuel economy, and even boating
and steering capabilities. An incorrect choice
could adversely affect performance and
could also seriously damage the engine.
Use the following information as a guide for
selecting a propeller that meets the operating
conditions of the boat and the outboard
motor.
a Propeller diameter (in inches)
b Propeller pitch (in inches)
c Propeller type (propeller mark)
Selection
When the engine speed is at the full throttle
operating range (5,000–6,000 r/min), the
ideal propeller for the boat is one that provides maximum performance in relation to
boat speed and fuel consumption.

Propeller selection / Predelivery checks
Predelivery checks
1
To make the delivery process smooth and
efficient, the predelivery checks should be
completed as explained below.
Checking the engine oil
1. Check the oil level.
Checking the fuel system
1. Check that the fuel hoses are securely
connected and that the fuel tank is full
with fuel.
NOTE:
• If the engine oil is above the maximum level
mark a, drain sufficient oil until the level is
between a and b.
• If the engine oil is below the minimum level
mark b, add sufficient oil until the level is
between a and b.
Recommended engine oil:
API: SE, SF, SG, or SH
SAE: 10W-30, 10W-40, or 20W-40
Oil capacity:
Without oil filter replacement:
2.0 L (2.1 US qt, 1.8 Imp qt)
CAUTION:
This is a 4-stroke engine. Do not use premixed fuel and 2-stroke outboard motor
oil.
Checking the battery
1. Check the capacity, electrolyte level, and
specified gravity of the battery.
Battery capacity: 12 V, 70–100 Ah
Checking the gear oil
1. Check the gear oil level.
2. Check that the red and black battery
cables are securely connected.
Checking the outboard motor
mounting height
S69W1070
69W3D1X
1. Check that the anti-cavitation plate is
aligned with the bottom of the boat. If the
mounting height is too high, cavitation
will occur and propulsion will be reduced.
Also, the engine speed will increase
abnormally and cause the engine to
overheat. If the mounting height is too
low, water resistance will increase and
reduce engine efficiency.

GEN
INFO
General information
S69W1110
NOTE:
The optimum mounting height is affected by
the combination of the boat and the outboard
motor. To determine the optimum mounting
height, test run the outboard motor at different heights.

General torques
This chart specifies tightening torques for
standard fasteners with a standard ISO
thread pitch. Tightening torque specifications
for special components or assemblies are
provided in applicable sections of this manual. To avoid warpage, tighten multi-fastener
assemblies in a crisscross fashion and progressive stages until the specified torque is
reached. Unless otherwise specified, torque
specifications require clean, dry threads.
Components should be at room temperature.

Checking the compression pressure
1. Start the engine, warm it up for 5 minutes, and then turn it off.
2. Remove the lock plate from the engine
shut-off switch on the remote control box
or tiller handle.
3. Remove all spark plugs, and then install
the special service tools to each spark
plug hole.
NOTE:
• If the compression pressure increases,
check the piston and piston rings for wear.
Replace if necessary.
• If the compression pressure does not
increase, check the valve clearance, valve,
valve seat, cylinder sleeve, cylinder head
gasket, and cylinder head. Adjust or
replace if necessary.
Checking the oil pressure
1. Remove the cover.
2. Remove the oil pressure switch, and then
install an oil pressure gauge 1 to the oil
pressure switch installation hole.
CAUTION:
Before removing the spark plugs, remove
any dirt or dust that may fall into the cylinder.
Compression gauge 1:
90890-03160
NOTE:
Use a pressure gauge with an adapter that
has a 1/8 pitch thread.
4. Fully open the throttle manually, crank
the engine until the reading on the compression gauge stabilizes, and then
check the compression pressure.
3. Start the engine and warm it up for 5 minutes.
Minimum compression pressure
(reference data):
880 kPa (8.8 kgf/cm2, 125 psi)
4. Check the oil pressure. Check the oil
pump, relief valve, oil filter, and oil
strainer if out of specification.
5. If the compression pressure is below
specification and the compression pressure for each cylinder is unbalanced, add
a small amount of engine oil to the cylinder, and then check the pressure again.

Shimming
NOTE:
• Shimming is not required when assembling
the original lower case and inner parts.
• Shimming is required when assembling the
original inner parts and a new lower case.
• Shimming is required when replacing the
inner part(s).
Selecting the forward gear shims
1. Turn the taper roller bearing outer race
1 two or three times to seat the rollers,
and then measure the bearing height (M)
as shown.
NOTE:
“F” is the deviation of the lower case dimension from standard. The “F” mark a is
stamped on the trim tab mounting surface of
the lower case in 0.01 mm units. If the “F”
mark is unreadable, assume that “F” is zero
and check the backlash when the unit is
assembled.
Calculation formula:
Forward gear shim thickness (T1) =
26.50 + F/100 – M
Example:
If “M” is 26.06 mm and “F” is (+1), then
T1 = 26.50 + (+1)/100 – 26.06 mm
= 26.50 + 0.01 – 26.06 mm
= 0.45 mm
3. Select the forward gear shim(s) (T1) as
follows.
NOTE:
• Select the shim thickness (T1) by using the
specified measurement(s) and the calculation formula.
• Measure the bearing outer race at three
points to find the height average.

2. Calculate the forward gear shim thickness
(T1) as shown in the examples below.

Example:
If “T1” is 0.45 mm, then the forward gear
shim is 0.42 mm.
If “T1” is 0.60 mm, then the forward gear
shim is 0.58 mm.
