Steering System Maintenance
A periodic inspection of all steering hoses, link-
age and helm assemblies should be made. Signs
of corrosion, cracking, loosening of fastenings,
excessive wear or deterioration should be cor-
rected immediately. Failure to do so could lead to
steering system failure that would result in loss of
control. Generally, periodic lubrication of all mov-
ing parts and connections with a light waterproof
grease is in order.
The uid level for the hydraulic steering should be
checked frequently and maintained at the proper
level. The steering uid level at the vent/ll plug
in the helm should be maintained at no less than
1/2” below the bottom of the ller cap threads.
When new or after repairs, hydraulic steering
systems may need to have all air purged from the
system. Only use hydraulic steering uid recom-
mended by the steering system manufacturer.
Difcult steering and premature seal failure can
result if the wrong uid is used in the steering
system.
Remove, clean and grease the engine support
tube and rod annually with quality marine grease.
Refer to the hydraulic steering manufacturer and
engine owner’s manuals for proper specications
and details on steering system service and main-
tenance.
