Maintenance
1. Drain screw
2. Gasket
TIP:
If the oil does not drain easily, change the tilt
angle or turn the outboard motor to port and
starboard to drain the oil.
7. Put a new gasket on the oil drain screw.
Apply a light coat of oil to the gasket and
install the drain screw.
Drain screw tightening torque:
F50B 28 Nm (2.86 kgf-m, 20.7 ft-lb)
F50HB 28 Nm (2.86 kgf-m, 20.7 ft-lb)
F60B 28 Nm (2.86 kgf-m, 20.7 ft-lb)
F60HB 28 Nm (2.86 kgf-m, 20.7 ft-lb)
F70A 27 Nm (2.75 kgf-m, 19.9 ft-lb)
F70HA 27 Nm (2.75 kgf-m, 19.9 ft-lb)
T50B 28 Nm (2.86 kgf-m, 20.7 ft-lb)
T60B 28 Nm (2.86 kgf-m, 20.7 ft-lb)
TIP:
If a torque wrench is not available when you
are installing the drain screw, finger tighten
the screw just until the gasket comes into
contact with the surface of the drain hole.
Then tighten 1/4 to 1/2 turn more. Tighten
the drain screw to the correct torque with a
torque wrench as soon as possible.
8. Add the correct amount of oil through the
filler hole. Put back the filler cap and the
88
dipstick. NOTICE: Overfilling the oil
could cause leakage or damage. If the
2
oil level is above the upper level
mark, drain until the level meets the
1
specified capacity.
