Warm‑Up
Run the engine at a low speed for about three minutes for warm‑up operation
before cruising, permitting the oil to circulate throughout the engine, otherwise
the life of the engine will be shortened greatly. During warm‑up operation,
confirm that cooling water is discharged from its water pump indicator hole.
IMPORTANT: If cooling water is not discharged, and operation continues, it
may cause overheating, resulting in engine damage.

Gear Shifting
FORWARD
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).
• Remote control models—always stop at the neutral position to allow the
engine idle speed to stabilize before shifting into another gear.
