TILTING UP AND DOWN

If the engine will be stopped for some time and the boat is moored in shallows, the outboard motor should

be tilted up to protect the propeller and casing from damage from collision with obstructions, and also to

reduce salt corrosion.

WARNING: Before tilting the outboard motor, follow the procedure under “Stopping Engine” in this section.

Never tilt the outboard motor while the engine is running. Severe damage from overheating can

result. Do not tilt the engine by pushing the tiller handle only because this could break the handle.

WARNING: Be sure all people are clear of the outboard motor when tilting up and down, also be careful not

to pinch any body parts between the drive unit and engine bracket.

PROCEDURE FOR TILTING UP

1. Place the gear shifter lever in neutral and face the outboard motor forward.

2. Tighten the steering friction adjuster by turning it clockwise to prevent the motor from turning freely.

3. Hold the carrying handle and tilt the engine up fully until the tilt support lever automatically locks.

PROCEDURE FOR TILTING DOWN

1. Slightly tilt the outboard motor up.

2. Slowly tilt the outboard motor down while pulling the tilt support lever up.

3. Loosen the steering friction adjuster by turning it counterclockwise, and adjust the steering friction

according to operator preference.

Use the carrying handle to help lift the engine. Keep the power unit higher than the propeller at all

times otherwise water could run into the cylinder and cause damage. The outboard motor cannot be

tilted when in reverse position.

BOW DOWN

Too much trim-in causes the boat to “plow” through the water, decreasing fuel economy and making it hard

to increase speed. Operating with excessive trim-in at higher speeds also makes the boat unstable.

Resistance at the bow is greatly increased, heightening the danger of “bow steering” and making operation

difficult and dangerous.

NOTE: Depending on the type of boat, the outboard motor trim angle may have little effect on the trim of the

boat when operating.
