Engine Over-Speed Limiter
The outboard is equipped with an engine over-speed limiter which limits the engine maximum RPM. This will protect
the engine from mechanical damage.
Some causes of engine over-speed are as follows:
• Outboard mounted too high on the transom.
• Worn jet pump impeller or liner.
• Incorrect jet pump impeller clearance adjustment.
• Tilting the outboard out beyond a vertical position.
• Cavitation of the impeller due to rough water or obstruction in the boat hull.
• Blockage of the water intake.
When the engine over-speed limiter is activated, it will reduce ignition voltage to momentarily decrease the engine
speed. Excessive over-speed (above 5700 RPM) will result in cutout of the cylinders to prevent operation above
this limit.
Power Trim And Tilt
The outboard has a trim/tilt control called power trim. This enables the operator to easily adjust the position of the
outboard by pressing the trim switch. Moving the outboard in closer to the boat transom is called trimming in or
down. Moving the outboard further away from the boat transom is called trimming out or up. The term trim generally
refers to the adjustment of the outboard within the first 20° range of travel. This is the range used while operating
your boat on plane. The term tilt is generally used when referring to adjusting the outboard further up out of the
water. With the engine turned off, the outboard can be tilted out of the water. At low speed, the outboard can also
be tilted part the trim range to permit, for example, shallow water operation.
