Throttle only button

‑ The throttle only button allows throttle

advancement without shifting the engine. The throttle only button

disengages the shifting mechanism from the control handle. The throttle

only button can be pressed and held in only when the remote control

handle is in the neutral position. While holding the throttle only button in,

move the throttle handle forward to assist in starting the engine.

•

Lanyard stop switch (if equipped)

‑ The purpose of a lanyard stop

switch is to shut down the engine when the operator moves far enough

away from the operator's position to activate the switch. A lanyard stop

switch can be installed as an accessory, generally on the dashboard or

side adjacent to the operator's position.

•

Control handle

‑ Operation of the shift and throttle is controlled by the

movement of the control handle. Push the control handle forward from

neutral with a quick firm motion to the first detent for forward gear.

Continue pushing forward to increase speed. Pull the control handle back

from neutral with a quick firm motion to the first detent for reverse gear.

Continue pulling back to increase speed.

IMPORTANT: Forcing the shift mechanism while the engine is not operating

can result in product damage.

GEAR SHIFTING

IMPORTANT: Observe the following:

•

Never shift the outboard into or out of gear unless the engine speed
is at idle. Shifting at higher than engine idle speed could cause
damage to the gearcase.

•

Do not shift the outboard into reverse when the forward motion of
the boat is greater than a no wake speed. Shifting into reverse at
higher boat speeds could cause the engine to stall, and in some
situations, this could cause water to be drawn into the cylinders,
resulting in severe engine damage.

•

Do not shift the outboard into reverse when the engine is not
running. Damage to the shift linkage could occur.

•

Your power package has three gear shift positions to provide operation:

forward (F), neutral (N), and reverse (R).

•

When shifting, always stop at the neutral position and allow the engine

speed to return to idle.

•

Always shift into gear with a quick motion.
