Operation
q
A continuous flow of water from the pilot
hole shows that the water pump is
pumping water through the cooling pas-
sages. If water is not flowing out of the
pilot hole at all times while the engine is
running, overheating and serious dam-
age could occur. Stop the engine and
check whether the cooling water inlet on
the lower case or the cooling water pilot
hole is blocked. Consult your Yamaha
dealer if the problem cannot be located
and corrected.

Shifting
Be sure the low oil pressure warning indi-

q
If the low oil pressure warning indicator
blinks after the engine starts, stop the
engine. Otherwise serious engine dam-
age could occur. Check the oil level and
add oil if necessary. Consult your
Yamaha dealer if the cause for the low
oil pressure warning indicator cannot be
found.
CAUTION:
Warm up the engine before shifting into
gear. Until the engine is warm, the idle
speed may be higher than normal. High
idle speed can prevent you from shifting
