TRIM LIMIT PIN (SINGLE-RAM TRIM)
!
WARNING
Operating the boat at high speeds with the outboard trimmed too far under
can create excessive bow steer, resulting in the operator losing control of the
boat. Install the trim limit pin in a position that prevents excessive trim under
and operate the boat in a safe manner.

a - Adjustment holes
b - Nut
c - Trim limit pin
A trim limit pin, secured with a nut, is included on both sides of the heavy‑duty
swivel bracket. The location of this pin will determine how far down the
outboard can be trimmed. Three adjustment holes are present on each transom
bracket to adjust the trim limit.
1. Remove the nut from the trim limit pin on both sides of the heavy‑duty
swivel bracket.
2. Remove the pins from and install them into the desired adjustment holes.
3. Install and tighten the nuts.
OPERATING IN SHALLOW WATER
When operating your boat in shallow water, you can tilt the outboard beyond
the maximum trim range to prevent hitting bottom.
1. Reduce the engine speed below 2000 RPM.
2. Tilt the outboard up. Make sure all the cooling water intake holes stay
submerged at all times.
• Below 2000 RPM the engine can be trimmed or tilted to any range.
Caution is advised when operating the engine past the tilt range. Ensure
the water pickups are submerged.
• If the engine is below 2000 RPM and is in the trailer range, advancing the
throttle will allow the engine to achieve a maximum RPM of 4250. Engine
operation in this capacity (above the normal 2000 limit) should only be
used for loading or unloading the boat onto or off the trailer. It should not
be used during normal boat operation.
