Setting Trim Angle While Running Engine at Idle
Speed
Submerging the exhaust relief hole on the outboard can happen
on some boats if you trim full in while running at idle speed,
resulting in, exhaust restriction, rough idle, excessive smoke,
and fouled spark plugs. If this condition exists, trim outboard up
until exhaust relief hole is out of the water.

submerged (wrong)
b - Relief hole above
waterline (correct)
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.
NOTICE
Operating the engine with the outboard in the tilt range can
damage the engine or the transom. If operating the engine in
the tilt range, such as in shallow water, do not exceed 2000
RPM.
1. Reduce engine speed below 2000 RPM.
2. Tilt outboard up. Make sure all the cooling water intake
holes stay submerged at all times.
3. Operate the engine at slow speed only.
Models with a three‑ram trim system: If engine speed exceeds
2000 RPM, the outboard will automatically return down to the
maximum trim range.
