PREFACE
This Assembly Manual contains the infor-
mation needed to assemble the Yamaha
water vehicle correctly prior to delivery to
the customer. Since some external parts of
the water vehicle have not been assemblied
at the Yamaha factory for convenience of
packing, assembly by the Yamaha dealer is
required. It should be noted that the reas-
sembled water vehicle should be thor-
oughly cleaned, inspected, and adjusted
prior to delivery to the customer.
NOTICE
Because Yamaha constantly strives for
product improvement, the service specifica-
tions may be subject to change in the
future. If any change is introduced into the
specifications or assembly procedures,
Yamaha dealers will be notified by a techni-
cal bulletin.

BATTERY
WARNING
●Battery electrolyte is poisonous and dan-
gerous, causing severe burns, etc. Con-
tains sulfuric acid.
●Avoid contact with skin, eyes or clothing.
●Antidote: EXTERNAL-Flush with water.
●INTERNAL-Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg or vegetable oil. Call a physi-
cian immediately. Eyes: Flush with water
for 15 minutes and get prompt medical
attention. Batteries produce explosive
gases. Keep sparks, flame, cigarettes,
etc., away. Ventilate when charging or
using in an enclosed space. Always shield
your eyes when working near batteries.
●KEEP OUT OF REACH OF CHILDREN.
CAUTION:
Be careful not to place the battery on its
side. Before adding the battery fluid or
recharging, be sure to bring it out of the
battery compartment. When checking the
battery, make sure the breather hose is
connected to the battery and is not pinched
shut anywhere in the battery compart-
ment.

1. Fill:
●Battery electrolyte
2. Initial battery charging:
●Battery
WARNING
Turn the battery charger on after the bat-
tery is connected to the charger.
The sparking by connecting the charging
cable to the battery terminal can cause an
explosion to the explosive gases coming
out from the battery cells.
CAUTION:
Always charge the battery when the elec-
trolyte is poured into the battery for the
first time. Otherwise, the battery can cause
the lowering of performance earlier.
3. Inspect:
●Specific gravity of the electrolyte
Out of specification →Recharge.
NOTE:
Replace the battery if there are differences
of 0.025 or more on the specific gravity of
each cell’s electrolyte after recharging.
Filling steps:
●Remove all the filler caps using pliers.
●Fill with the specified electrolyte from
a jug.
●After the electrolyte is filled up as far as
the UPPER LEVEL a, allow the cell to
stand for 20 minutes. If after 20 min-
utes, the electrolyte level has dropped,
add more electrolyte up to the UPPER
LEVEL mark once again.
Charging steps:
●Connect the charging cable (+) and (–)
of the battery charger to the battery
terminals correctly.
●Charge the battery for 3 to 5 hours
with the rate of 1.9 ampere.
Specific gravity at 20˚C (68˚F):
1.28

4. Install:
●Filler caps
CAUTION:
Rinse off any electrolyte from the battery
case and wipe the battery dry prior to
installation.
OIL PUMP AIR BLEEDING
1. Bleed:
●Air
CAUTION:
●Do not run the engine if oil does not flow
out the air bleed screw. Inspect the oil
lines for proper routing and make sure
there are no restrictions in the line.
●Fill the fuel tank with 50:1 premixed fuel
using the recommended engine oil during
the first full tank of operation.
Air bleeding steps:
●Place rags around the air bleed screw
1to catch any oil that might spill.
●Fill the oil tank with the recommended
engine oil.
Recommended engine oil:
YAMALUBE 2-W or an
equivalent TC-W3 certified
outboard oil
●Loosen the air bleed screw 1two full
turns and make sure that both the oil
and air bubbles flow out.
●When there are no air bubbles left,
tighten the air bleed screw.
●Wipe up any spilt oil.

TROLLING SPEED
1. Measure:
●Trolling speed
Out of specification →Adjust.
Trolling speed:
1,300 ±50 r/min
Checking steps: (Vehicle on water)
●Start the engine and allow it to warm
up for a few minutes.
●Attach an engine tachometer to the
spark plug lead.
Engine tachometer:
YU-8036-A/90890-06760
●Measure the engine trolling speed.
2. Adjust:
●Trolling speed
Adjustment steps:
●Start the engine.
●Turn the throttle stop screw 1in or
out until the specified speed is
obtained.
Turn in Increase trolling speed.
Turn out Decrease trolling speed.
