TILTING OUTBOARD TO FULL UP POSITION

1
Stop the engine. Shift the outboard into forward gear position.
2
Take hold of the top cowl grip and raise outboard to the full up position.
3
Move the tilt lock to the lock position.

LOWERING OUTBOARD DOWN TO RUN POSITION

4
Lift outboard and release tilt lock lever. Lower outboard.

SHALLOW WATER OPERATION - TILLER HANDLE
MODELS
Tiller handle model outboards are equipped with a shallow water tilt feature that
allows you to tilt the outboard to a higher tilt angle to prevent hitting bottom.
Engaging Shallow Water Drive
1
Reduce engine speed to idle. Shift the outboard into neutral or forward gear
position.
2
Push down the shallow water drive lever (a).Tilt outboard up to the shallow
water drive position. Be sure the cooling water intake (c) is submerged.
IMPORTANT: While in shallow water drive position, do not operate the
outboard in reverse. Operate the outboard at slow speed and keep the
cooling water intake submerged.
3
To release down to run position, lift up the shallow water drive lever (b). Tilt up
the outboard to disengage the shallow water drive lock and lower it down.

SETTING THE OPERATING ANGLE OF YOUR
OUTBOARD
The vertical operating angle of your outboard is adjusted by changing the position
of the tilt pin (a) in the five adjustment holes provided. Proper adjustment allows
the boat to run stable, achieve optimum performance, and minimize steering effort.
Note: Refer to lists on the following page when adjusting the operating angle of
your outboard.
The tilt pin should be adjusted so the outboard is positioned to run perpendicular
to the water when the boat is running at full speed. This allows the boat to be driven
parallel to the water.
Arrange passengers and load in the boat so the weight is distributed evenly.
1
Too Much Angle (Stern Down - Bow Up)
2
Not Enough Angle (Stern Up - Bow Down)
3
Angle Adjusted Properly (Bow Slightly Up)
SETTING THE OPERATING ANGLE OF YOUR
OUTBOARD (CONTINUED)
Consider the following lists carefully when adjusting the operating angle of your
outboard.
Adjusting the outboard close to the boat transom can:
1. Lower the bow.
2. Result in quicker planing off, especially with a heavy load or a stern heavy boat.
3. Generally improve the ride in choppy water.
4. Increase steering torque or pull to the right (with the normal right hand rotation
propeller).
5. In excess, lower the bow of some boats to a point at which they begin to plow
with their bow in the water while on plane. This can result in an unexpected turn
in either direction called "bow steering" or "over-steering" if any turn is
attempted or if a significant wave is encountered.
Adjusting the outboard away from the boat transom can:
1. Lift the bow out of the water.
2. Generally increase top speed.
3. Increase clearance over submerged objects or a shallow bottom.
4. Increase steering torque or pull to the left at a normal installation height (with
the normal right hand rotation propeller).
5. In excess, cause boat "porpoising" (bouncing) or propeller ventilation.
