Predelivery check
To make the delivery process smooth and
efficient, the predelivery checks should be
completed as explained below.
Checking the fuel system
1.
Check that the fuel hoses is securely
connected and that the fuel tank is filled
with fuel.
c
C
Use pre-mixed fuel only.
Fuel and oil mixing ratio is 50:1. For
break-in period, 25:1 mixture shall be
used.
Checking the gear oil
1.
Check the gear oil level.
Checking the battery
(E, ET, WH)
1.
Check the capacity, electrolyte level, and
specified gravity of the battery.
2.
Check that the positive and negative bat-
tery cable are securely connected.
Checking the outboard motor
mounting height
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 over-
heat. If the mounting height is too low,
water resistance will increase and reduce
engine efficiency.
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 differ-
ent heights.
2.
Check that the clamp brackets are
secured with the mounting bolts.
