STORING OUTBOARD MOTOR

When storing your Yamaha outboard
motor for prolonged periods of time (2
months or longer), several important pro-
cedures must be performed to prevent
excessive damage. This is especially
important for your oil injection-equipped
outboard motor due to the lean oil ratios
used at idle prior to shutting the engine
off for the season. It is advisable to have
your outboard motor serviced by an
authorized Yamaha dealer prior to stor-
age. However, the following procedures
can be performed by you, the owner, with
a minimum of tools.
