Gear Shifting; Stopping The Engine - Mercury 150 Operation, Maintenance And Installation Manual

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.
• The outboard has three gear shift positions: forward (F), neutral (N), and
reverse (R).
• When shifting, always stop at the neutral position and allow the engine
idle speed to stabilize before shifting into another gear.
• Always shift the outboard into gear with a quick motion.
• After shifting the outboard into gear, advance the lever further to increase
speed.

Stopping the Engine

Reduce the engine speed and shift the outboard to neutral position. Turn the
ignition key to "OFF" position.
