CHECKING POWER TRIM FLUID (SINGLE-RAM TRIM SYSTEMS)
1. Place outboard in the full down/in position.
2. Check the fluid level in the trim pump reservoir. The level should be
between the "MIN" and "MAX" level marks on the reservoir.
3. If necessary, remove the yellow fill cap and add Power Trim and Steering
Fluid until the level in the reservoir reaches the "MIN" level mark. It is
acceptable to fill the reservoir beyond the "MIN" level mark, but do not
overfill past the "MAX" level mark.
