Checking The Gear Oil; Checking The Battery; Checking The Outboard Motor Mounting Height; Checking The Remote Control Cable (Ed, Et) - Yamaha 55DEHD Service Manual

Checking the gear oil

1. Check the gear oil level.
Recommended gear oil:
Hypoid gear oil
API: GL-4
SAE: 90
Oil quantity:
610 cm 3
(20.62 US oz, 21.51 Imp oz)

Checking the battery

1. Check the capacity, electrolyte level, and
specified gravity of the battery.
Recommended battery capacity:
CCA/EN: 430 A
20HR/IEC: 70 Ah
Electrolyte specified gravity:
1.280 at 20°C (68°F)
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:
69D10055 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.
Checking the remote control cable
(ED, ET)
1. Set the remote control lever to "N" posi-
tion and the throttle lever to fully-closed
