Power Tilt Operation (Single-Ram Systems); Power Tilt Operation (Three-Ram Trim Systems) - Mercury 250 XS OptiMax Operation, Maintenance & Installation Manual

To limit trim in on models with a single‑ram trim system, use the 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.
