Check the propeller

Check the area just forward

to
be sure
a fish

is not
wrapped around the shaft.
Operation At Recommended RPM
Check
with the local OMC dealer,
or a
propeller
shop
for
the
recommended

and intended
operation.
The correct
propel-
ler
should
be
installed
on the
engine
to
enable operation
at recommended
rpm.
Two rpm ranges
are usually given.
The
lower rpm is recommended
for large,
heavy
slow boats,
or for commercial
applications.
The higher
rpm is recommended
for
light,
fast
boats.
The wide rpm range will result
in greater
satisfaction
because
of maximum
performance
and greater
fuel economy.
If
the engine speed is above the recommended
rpm,
try

See
Chapter
1 for

terms,

For a dual engine
installation,
the next

propeller
may prove the
most
satisfactory
condition
for water skiing.

LOWER
UNIT
NEVER
remove
the vent
or filler
plugs
when the lower unit is hot.
Expanded lubri-
cant
would
be
released
through

plug
hole.
Check
the
lubricant
level
after
the
unit
has been
allowed
to cool.
Add only
OMC approved
gear lubricant.
NEVER
use
regular

grease in the lower

New propeller
ready for
installation.
On the smaller
horsepower
engines,
a
damaged
propeller
can
cause
excessive
vibration,
resulting
in failure
of more expen-

sive parts.
The modest
cost
of
a
new
propeller
is
therefore
justified.
Rebuilding
a
small propeller
is not
economical
when balanced
against
the minor
difference
of purchasing
a new
unit.
