Power Trim/Tilt & Steering Fluid. Install and
tighten the reservoir cap. Turn the manual release
valve in until it seats. Cycle the unit up and down

down momentarily to release pressure. Check the
fluid level again and add fluid, if necessary.

check the fluid level. Test the unit by performing
the Pressure Leakdown Test on p. 367.
