Counter rotation models
Standard outboard motors rotate clockwise.
Counter rotation models rotate counterclock-
wise and are typically used in multiple motor
setups.
On counter rotation models, be sure to use a
propeller intended for counterclockwise rota-
tion. These propellers are identified with the
letter "L" after the size indication on the pro-
peller. WARNING! Never use a standard
propeller with a counter rotation motor,
or a counter rotation propeller with a
standard motor. Otherwise the boat could
go in the direction opposite of that ex-
pected (for example, reverse instead of
forward), which could lead to an accident.

stallation, see page 89.
