ADJUSTMENT AND

MAINTENANCE

Periodic inspection, adjustment, and
lubrication will keep your Jet Boat in
the safest and most efficient condition
possible. Safety is an obligation of the
Jet Boat owner. The most important
points of boat inspection, adjustment
and lubrication are explained on the
following pages.

________________

●

Be sure to turn off the engines
when you perform maintenance
unless otherwise specified.
Otherwise, accident or injury
could result from unexpected
operation, moving parts, or elec-
tric shock.

●

If the owner is not familiar with
machine servicing, this work
should be done by a Yamaha
dealer or other qualified mechan-
ic. Improperly serviced compo-
nents could fail or stop operating
correctly, which could result in an
accident.

TOOL KIT

It is advisable always to carry the
Owner's Manual and tool kit with you
whenever you use the Jet Boat. To pro-
tect these articles from water, it is a
good idea to put them in a vinyl bag.

The service information included in this
manual is intended to provide you, the
owner, with the necessary information
for completing your own preventive
maintenance and minor repairs. The
tools provided in the owner's tool kit
are sufficient for this purpose, except
that a torque wrench is also necessary
for tightening nuts and bolts properly.

________________

Do not attempt to modify this Jet
Boat! Modifications to your boat
may reduce safety and reliability,
and may make the boat illegal for
use.
