STEERING SYSTEM OVERVIEW
STERN DRIVE STEERING
Your typical stern drive (outdrive) vessel uses a rack or
rotary style helm located steering system. This system
transfers helm mechanical energy to the engine. There is
a hydraulic steering cylinder as part of the engine along
with a steering pump which sends fluid force to the stern
drive steering arm changing the course of the boat,
depending on the direction the steering wheel is turned.
Since the steering system is the primary link for engine
control it must be periodically inspected and maintained.
The hardware at both the helm and engine locations must
be checked regularly for tightness and/or leakage.
Refer to the steering manufacturer’s literature in the owner’s
packet for more information along with the following
illustration.
