6. If fluid is not visible in the reservoir, a leak exists in the power‑assisted steering system. Find the cause and correct.
Filling and Bleeding
IMPORTANT: The power‑assisted steering system must be filled exactly as explained to ensure that all air is bled from the
system. All air must be removed or fluid in the pump may foam during operation and be discharged from the pump reservoir.
Foamy fluid may also cause the power‑assisted steering system to become spongy, which may result in poor boat control.
1. With the engine stopped, center the sterndrive.
2. Remove the fill cap/dipstick from the power‑assisted steering pump.
IMPORTANT: Use only specified fluid in the power‑assisted steering system.
3. Add the specified fluid, as required, to bring the level up to the appropriate mark on the dipstick depending on the fluid
temperature.
