Inspecting engine idle speed

ECM01691
NOTICE
This procedure must be performed while
the outboard motor is in the water.
Inspect the engine idle speed using the 6Y8
Multifunction tachometer or digital tachome-
ter that is equipped on the boat. Results may
vary depending on whether testing is con-
ducted with the outboard motor in the water.
1. Start the engine and allow it to warm up
fully in neutral until it is running smooth-
ly.
2. Inspect the engine idle speed. If the en-
gine idle speed is out of specification,
consult a Yamaha dealer or other quali-
fied mechanic.
Idle speed (in neutral):
650–750 r/min (VF250XA)
700–800 r/min (VF200A, VF225A,
VF250LA)
