Periodic maintenance

EWM01872
These procedures require mechanical
skills, tools, and supplies. If you do not
have the proper skills, tools, or supplies
to perform a maintenance procedure,
have a Yamaha dealer or other qualified
mechanic do the work.
The procedures involve disassembling
the motor and exposing dangerous parts.
To reduce the risk of injury from moving,
hot, or electrical parts:
Turn off the engine and keep the key(s)

and engine shut-off cord (lanyard) with
you when you perform maintenance un-
less otherwise specified.
The power trim and tilt switches oper-

ate even when the ignition key is off.
Keep people away from the switches
whenever working around the motor.
When the motor is tilted, keep away
from the area under it or between it and
the clamp bracket. Be sure no one is in
this area before operating the power
trim and tilt mechanism.
Allow the engine to cool before han-

dling hot parts or fluids.
Always completely reassemble the mo-

tor before operation.
