Tilt Pin Adjustment
1. The vertical operating angle of the outboard is adjusted by changing the position of the tilt pin in the adjustment holes
provided. Proper adjustment allows the boat to run stable, achieve optimum performance, and minimize steering effort.
2. 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.
3. Arrange the passengers and the load in the boat so the weight is distributed evenly.

Engine Overspeed Protection System
The system is activated if the engine speed should ever exceed the maximum allowable limit. This will protect the engine from
mechanical damage.
Anytime the engine overspeed system is activated, the system will automatically reduce the engine speed to within the
allowable limit. If the engine overspeed continues, the outboard should be inspected by an authorized mechanic.
NOTE: The engine speed should never reach the maximum limit to activate the system unless the propeller is ventilating, an
incorrect propeller is being used, or the propeller is faulty.
