2.4 Engine Power Tilt and Trim
All outboard engines have a tilt and trim feature.
Most outboard engines have tilt/trim switches built
into the engine shift and throttle controls that allow
the operator to control the position of the outboards
from the helm. Typically, a switch or switches on the
port control lever grip activates the tilt/trim for the
engines. Yamaha engine controls have two switches
on the cover that activate each engine tilt/trim in-
dividually. The maximum tilt angle on the Yamaha
F350 engines is preset at the factory. If necessary,
the maximum tilt angle can be adjusted by your
Scout or Yamaha dealer by reprogramming the set-
tings using the Yamaha engine diagnostic system.
Moving the outboard closer to the boat transom is
called trimming “in” or “down.” Moving the outboard
further away from the boat transom is called trim-
ming “out” or “up.” In most cases, the boat will run
best with the outboard adjusted so the hull will run
at a 3 to 5 degree angle to the water.
The term “trim” generally refers to the adjustment
of the outboard within the first 20o range of travel.
This is the range used while operating your boat on
plane. The term “tilt” is generally used when refer -
ring to adjusting the outboard further up for shallow
water operation or trailering. For information on the
proper use and maintenance of the power tilt and
trim, please refer to the engine owner’s manual.
THE ENGINE HOSES AND CABLES OR THE TRANSOM GEL
COAT CAN BE DAMAGED BY TILTING THE ENGINES TO THE
FULL UP POSITION WITH THE ENGINES TURNED TO THE
WRONG POSITION. MOST BOATS REQUIRE THE STEERING
WHEEL TO BE TURNED COMPLETELY TO STARBOARD BEFORE
TILTING THE ENGINES TO THE FULL UP POSITION. YOU
SHOULD MONITOR EACH ENGINE AS IT TILTS TO DETERMINE
BEST FULL TILT ENGINE POSITION FOR YOUR BOAT.
SOME AUTOPILOTS HAVE ENGINE POSITION SENSORS THAT
ARE MOUNTED TO THE HYDRAULIC STEERING CYLINDER.
WITH THESE AUTOPILOTS, THE ENGINE POSITION SENSOR
BRACKET COULD HIT THE TRANSOM WHEN THE ENGINES ARE
TILTED TO THE FULL UP POSITION AND CAUSE DAMAGE TO
THE ENGINE RIGGING, THE AUTOPILOT OR THE TRANSOM. IF
YOU HAVE AN AUTOPILOT INSTALLED ON YOUR BOAT, YOU
SHOULD MONITOR THE LOCATION OF THE ENGINE CABLES
AND AUTOPILOT BRACKETS AS THE ENGINES ARE TILTED
TO DETERMINE THE BEST ENGINE POSITION AND MAXIMUM
ENGINE TILT FOR YOUR APPLICATION.

2.5 Engine Stop Switch
Your boat is equipped with an engine stop switch
and lanyard. When the lanyard is pulled it will
engage the switch and shut off the engines. We
strongly recommend that the lanyard be attached
to the driver whenever the engines are running.
If an engine will not start, it could be because the
lanyard is not properly inserted into the engine
stop switch. Always make sure the lanyard is
properly attached to the engine stop switch before
attempting to start the engines.
Refer to the engine owner’s manual for more in -
formation on the engine stop switch.
