Outboard Rigging
Filling and Bleeding the Hydraulic Steering System
6. Rotate the steering wheel both clockwise and
counter–clockwise until air bubbles are no lon-
ger visible.
7. Remove the steering lock tool.
8. Turn the steering wheel clockwise until engine
is turned fully to STARBOARD and resistance
is felt.
9. Install the steering lock tool, P/N 357717, to
hold engine in full STARBOARD turn.
Use a shipping bracket screw to attach the long
end of the steering lock tool to the steering arm.
Attach the short end of the tool to the stern
bracket using the provided nut and washer.
10.Rotate the steering wheel both clockwise and
counter–clockwise until air bubbles are no lon-
ger visible.
11.Tighten both bleed valves to a torque of 84 to
120 in.lb. (9.5 to 13.5 N·m). Then turn the
purge unit OFF.
12.Disconnect the return lines of the power purge
from the two bleed valves of the steering sys-
tem.
13.Disconnect the hydraulic fluid supply line of the
power purge from the helm.’
14.Install the fill cap on the helm, tighten securely.
15.Perform Steering System Checks.
Steering System Checks
1. Turn steering wheel to PORT. After engine is
turned fully to PORT, apply enough force to the
steering wheel to exceed the pressure relief
valve pressure of the helm.
2. While pressure is maintained on helm, check
all PORT lines and fittings for leaks.
3. Turn steering wheel to STARBOARD. After
engine is turned fully to STARBOARD, apply
enough force to the steering wheel to exceed
the pressure relief valve pressure of the helm.
4. While pressure is maintained on helm, check
all STARBOARD lines and fittings for leaks.
5. Repair all leaks. Repeat steps 1 through 4
before continuing.
6. Cycle the steering system from full PORT turn
to full STARBOARD turn several times. Defi-
nite resistance should be felt when the steering
wheel is turned full PORT or full STARBOARD.
IMPORTANT: If definite resistance is NOT felt,
or if steering feels loose or “soft” wait 15 minutes
and repeat the bleeding process.
7. Check the fluid level of the helm pump and fill
per the manufacturers recommendation.
8. Check mechanical free play.
Some free play movement of the steering system
is normal. To check mechanical free play:
• Make sure the anti-ventilation plate of the gear-
case is approximately level.
• Make a mark in the center/rear of the anti-venti-
lation plate of the gearcase.
• Center a stationary object, such as a length of
threaded rod attached to a plate, behind the
mark on the gearcase to serve as a reference
point.
