3. To release outboard back down to run position, tilt outboard up slightly
(approximately 15°), then pull up on the tilt release lever. Gently lower
outboard down to the normal running position.

Please follow the instructions below.
• Be sure that the water intake is submerged at all times and that water is
continuously flowing from the cooling water pump indicator hole.
• Be sure to run the engine slowly when using the shallow water drive.
Running at higher speeds will result in lack of control and may damage
the mounting bracket.
• Care must be taken while running in this tilt position not come in contact
with the bottom, or submerged objects, especially in reverse. This may
cause damage to the motor and/or boat.

Trim Angle Adjustment

The vertical operating angle of your outboard is adjusted by changing the
position of the tilt pin in the adjustment holes provided. Proper adjustment
allows the boat to achieve optimum performance, stability, and minimize
steering effort.
The following instructions explain how to set the best angle of the boat.
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.
The trim angle is adjusted by setting the trim position pin in the correct trim
position.
TRIM POSITION ADJUSTMENTS
•
Correct trim: The trim angle is optimum when the boat is parallel to the
water surface while running.
•
Trim down: If the trim angle is excessive, the bow will rise out of the
water and the speed will decrease. Furthermore, the bow may sway or the
bottom may slam the water while cruising. In this case, decrease the trim
angle by setting the trim position pin in a lower position.
