STEERING SYSTEM MAINTENANCE

A periodic inspection of all stern drive steering cables,
linkage and helm assemblies should be made. With
inboard models a periodic inspection of the helm pump
and reservoir, hydraulic hoses, the hydraulic cylinder, tie
bar assembly, bearing, seals, rudder angle sender and
rudder should be made. See Figures G4 - G6. Signs of
corrosion, cracking, loosening of fastenings, excessive
wear, or deterioration should be immediately corrected.
Failure to do so could lead to steering system failure and
corresponding loss of control.
The helm and cable assembly (if applicable) should be
so adjusted that the steering wheel is centered with the
drives or rudders in the straight ahead position. There
should be an equal number of turns to port and starboard
from the straight ahead position. If adjustment becomes
necessary, see your Four Winns dealer.
All cables, helm assemblies, and steering connections
should be periodically lubricated with a light, waterproof
grease or as indicated in the manufacturers information
provided in the owner's packet.
Inboard boats should also be inspected for leakage around
the rudder port seal. The packing nut(s) should be tight
enough to prevent leakage, yet loose enough so exces-
sive drag is not placed on the rudder shafts. Hard steer-
ing could otherwise result. If the leakage cannot be stopped
without exerting excessive drag on the rudder shaft, re-
placement of the seal is required.
To prevent water from entering into the boat, al-
ways be sure the lock nuts are tightened securely
to prevent the packing nuts from loosening.
Hydraulic steering systems must periodically have all air
purged from the system. Review the information provided
by the hydraulic steering manufacturer for proper specifi-
cations and details on system service and maintenance.
