Checking the fuel line
1. Check that the fuel hoses are connected
securely. See “Fuel hose” (6-1).
This outboard motor is equipped with a 4-
stroke engine. Never use premixed fuel or
2-stroke outboard motor oil.
Checking the gear oil level
1. Place the outboard motor in an upright
position.
2. Remove the check screw “1” and gasket
“2”, and then check the gear oil level.
TIP:
If the oil is at the proper level, a small amount
of oil should flow out of the check hole.
3. Install a new gasket and the check screw,
and then tighten the check screw to the
specified torque.
Checking the shift link/shift cable
and throttle link/throttle cable/
throttle pick-up timing
Do not overtighten the friction adjuster. If
there is too much resistance, it could be
difficult to operate the remote control
lever, which could result in an accident.
1. Check that the gear shift operates
smoothly when the remote control lever
is moved from the N position to the F or R
position.
2. Check that the throttle operates smoothly
when the remote control lever is moved
from the F or R position to the fully open
position.
Checking the outboard motor
mounting height
1. Check that the anti-cavitation plate “1” is
aligned with the bottom of the boat “2”. If
the mounting height is too high, cavita-
tion will occur and propulsion will
decrease. Besides, the engine speed will
increase abnormally and cause the
engine to overheat. If the mounting
height is too low, water resistance will
increase, which will decrease engine effi-
ciency and performance.
