Counter Rotation Models; Start-In-Gear Protection; Engine Oil Requirements - Yamaha F350 Owner's Manual

Specifications and requirements
pitch propeller for a heavier load. If you carry
loads that vary widely, select the propeller
that lets the engine run in the proper range
for your maximum load but remember that
you may need to reduce your throttle setting
to stay within the recommended engine
speed range when carrying lighter loads.
Yamaha recommends to use a propeller suit-
able for the "Shift Dampener System (SDS)".
For further information, consult your Yamaha
dealer.
To check the propeller, see page 111.

Counter rotation models

Standard outboard motors rotate clockwise.
Counter rotation models rotate counterclock-
wise. Counter rotation models are typically
used in multiple motor setups and are
marked with an "L" on the gear case above
the anti-ventilation plate.
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
18
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 112 and 112.

Yamaha outboard motors or Yamaha-ap-
proved digital electronic control units are
equipped with start-in-gear protection de-
vice(s). This feature permits the engine to be
started only when it is in neutral. Always se-
lect neutral before starting the engine.
