Tighten the filler cap securely after
refueling.

If you should swallow some gasoline,
inhale a lot of gasoline vapor, or get
gasoline in your eyes, get immediate
medical attention.

If any gasoline spills onto your skin,
immediately wash with soap and
water. Change clothing if gasoline
spills on it.

CAUTION:@ Use only fresh gasoline that has been
stored in clean containers.

Gasohol
There are two types of gasohol: gasohol
containing ethanol and that containing meth-
anol.
Gasohol containing ethanol can be used
if ethanol content does not exceed 10% and
the fuel meets minimum octane ratings.
Gasohol containing methanol is not rec-
ommended by Yamaha because it can
cause fuel system damage or engine perfor-
mance problems.Recommended gasoline:
Regular unleaded gasoline with
a minimum octane rating of
86 (Pump octane number) = (R+M)/2
90 (Research octane number)

Checking the engine oil level again:
1. Launch the watercraft, and then start the
engine.
2. Run the engine at 7,000 r/min for
5 minutes or more and at trolling speed
for 2–3 minutes, and then turn the
engine off.
3. Remove the oil tank filler cap, wipe the
dipstick clean, insert it back into the filler
hole, and then remove it again to check
the oil level.
4. If the engine oil is below the minimum
level mark, add sufficient oil of the rec-
ommended type to raise it to the correct
level. If the engine oil is above the maxi-
mum level mark 3, extract sufficient oil
to lower it to the correct level.
NOTE:@
The engine oil should be between the
minimum and maximum level marks.

To check the engine oil level accurately,
be sure to adequately warm the engine
up.

Water separator
Check the water separator 1 for water.
Normally the water separator is empty. The
water separator retains any water entering
through the fuel tank breather hose if the
watercraft is capsized.
If water remains in the water separator,
drain it by removing the drain screw 2.
Place a drain pan under the water separator
to catch the draining water or use a dry cloth
to soak up any water that could spill into the
watercraft. If any water spills into the water-
craft, be sure to wipe it up with a dry cloth.
Be sure to install the drain screw after drain-
ing the water separator.
