Proper Outboard Tilt Positioning During Periods of Non‑Use
With the engine turned off, tilt the outboard up to a point where the trailing edge
of the anti‑ventilation plate is angled higher than the leading edge.
With the engine off, the outboard tilt angle will:
• Help to eliminate or reduce engine smoke on start‑up. Tilting the outboard
up, allows oil in the cylinders to run down cylinders and return to the oil
sump. With the outboard level or tilted in, oil from the cylinder walls can
run down to the bottom of the cylinder and form a puddle behind the
piston/rings. The oil can then weep into the combustion chamber. When
the engine is started, the oil in the combustion chamber will burn, creating
smoke on start‑up condition. As the engine runs, the smoke will gradually
clear as the oil is consumed.
• Provides additional impact clearance for the gearcase/propeller, when the
boat is at rest in shallow water. Tides and wave action can vary the
waters depth and reduce the impact clearance between the gearcase/
propeller and the bottom.
