NOTICE
Failure to take proper precautions when servicing the outboard motor can cause damage to the parts
or the outboard motor.
To prevent the parts or the outboard motor from damage, be sure to take the following precautions:
• When removing parts that are to be reused, keep them arranged in an orderly manner so that they
may be reinstalled in the proper order and orientation.
• Be sure to use special tools where instructed.
• Make sure that all parts used in assembly are clean and also lubricated when specified.
• When use of a certain type of lubricant, bond, or sealant is specified, be sure to use the specified
type.
• When removing the battery, disconnect the negative cable first and then the positive cable. When
reconnecting the battery, connect the positive cable first and then the negative cable.
• When performing service to electrical parts, if the service procedures do not require using battery
power, disconnect the negative cable at the battery.
• Do not expose connectors and electrical parts to water, which will cause electrical systems
problems.
• Always be careful not to drop electrical components (ECM, relays, etc.) or handle them in a rough
manner.
• Whenever you remove oil seals, gaskets, packing, O-rings, locking washers, locking nuts, cotter
pins, circlips, and certain other parts as specified, always replace them with new ones. Also, before
installing these new parts, be sure to remove any left over material from the mating surfaces.
• Never reuse a circlip. When installing a new circlip, take care not to expand the end gap larger than
required to slip the circlip over the shaft. After installing a circlip, always ensure that it is completely
seated in its groove and securely fitted.
• Use a torque wrench to tighten fasteners to the torque values when specified.
• Remove grease or oil from screw / bolt threads unless a lubricant is specified.
• After assembly, check parts for tightness and proper operation.
NOTE
• To protect the environment, do not unlawfully dispose of used motor oil, other fluids or batteries.
• To protect the Earth's natural resources, properly dispose of used motor parts.
