cadmium plated bolt shipped with the engine.
a - Stainless steel tilt pin (Three-Ram trim system)
b - Bolt shipped with engine (Single-Ram trim system)
Trimming out or up can:
• Lift the bow higher out of the water.
• Generally increase top speed.
• Gain clearance over submerged objects or a shallow bottom.
• Increase steering torque or pull to the left at a normal
installation height (with the normal right hand rotation
propeller).
• In excess, cause boat porpoising (bouncing) or propeller
ventilation.
• Cause engine overheating if any cooling water intake holes
are above the water line.

Power Tilt Operation (Single-Ram Systems)

To tilt the outboard, shut off the engine and press the trim/tilt switch
or the auxiliary tilt switch to the up position. The outboard tilts up
until the switch is released or it reaches the maximum tilt position.
The hydraulic system is fully capable of supporting the outboard
during normal tilting operation. However, if trailering the boat in the
trim/tilt position, use an accessory outboard support device.

Power Tilt Operation (Three-Ram Trim Systems)

To tilt the outboard, shut off the engine and press the trim/tilt switch
or the auxiliary tilt switch (located on the cowl) to the up position.
The outboard tilts up until the switch is released or it reaches the
maximum tilt position.
