matter is found in the filter, replace it. For re-

Yamaha dealer.
1.
Start the engine and allow it to warm up
fully in neutral until it is running smooth-
ly.
2-hp
model: Warm the engine with the
throttle in the start position or less. If the
outboard is mounted on a boat, be sure
the boat is tightly moored.
NOTE:
Correct idling speed inspection is only possi-
ble if the engine is fully warmed up. If not
warmed up fully, the idle speed will measure
higher than normal. If you have difficulty ver-
ifying the idle speed, or the idle speed re-
quires adjustment, consult a Yamaha dealer
