4.3 System checks

At this point the system must be checked for fluid level, possible leaks, air
removal, and possible interference. Perform all the checks in this section and
correct any deficiencies before considering the installation to be complete.
NOTICE!
All these checks should be performed with the power assist off to avoid
any potential damage due to high steering forces.
WARNING!
Failure to perform these checks and correct deficiencies may result in
loss of steering control, leading to a collision and/or ejection from the
boat resulting in property damage and/or personal injury or death.

Air removal check

4.3.1
Remove the fluid fill cap from the helm.
While turning the steering wheel, observe the fluid level in the helm
pump. If the level rises and falls as you turn the wheel there is still air in
the system. Repeat the purge procedure until there is no obvious fluid
level change in the helm.
Pull on the rudder, engine leg, or anti-cavitation plate to manually move
the engine/rudder side to side. You should not be able to move the
steering cylinder more than 1/4" (1/8" is ideal). If you can, repeat the
purge procedure until you can't.

Fluid level check

4.3.2
• Helms mounted with the wheel shaft horizontal must be filled to the
bottom of the fill port.
• Helms mounted with the wheel shaft between 20° and vertical must be
filled to within 1/2" of the fill port as shown in figure 4-18.
