Sometimes the trim tab may need adjustment on stern drive models.
Contact your Regal dealer for further information or consult your
engine manufacturer’s manual.
Turning
Once the boat has gathered headway, with the boat planing at the
correct bow angle and the stern drive unit and helm straight the
boat tends to stay on a uniform course heading. To assure the boat
trim angle is correct use the trim gauge as a guide while activating
the trim button on the remote control panel.
When the helm wheel is turned to the right or starboard, the stern
drive unit is turned in the same direction. e propeller’s discharge
force is directed to starboard forcing the boats stern to port. Water
owing past the hull strikes the stern drive gear housing in its
starboard side, creating additional turning torque. e stern starts
a move to port, forcing the bow to starboard.
If the helm is turned to the le or port the stern drive turns to port,
the stern of the boat goes starboard as the bow turns to port.
As the vessel operator gains experience, he will better gauge each
maneuver and speed situation. In this way he will understand the
handling characteristics of his boat. He needs to keep the safety of
his passengers in the highest priority.
Backing Down
Inboard/Outboard (I/O) boats do not have rudders. e boat uses a
steering system that directs the propeller thrust, by turning the stern
drive unit where the propeller is mounted. Normally maneuvering
the I/O boat is easier than a similar single screw vessel.
If your boat has the steering wheel and stern drive straight with
the control in reverse, the stern will be pushed a bit to port by the
reversing propeller thrust. is tendency to back to port can be
eliminated by turning the stern drive to starboard.
