STERN DRIVE PROPELLER ROTATION

Volvo Stern Drive Shown
Shown in the illustration above is a Volvo stern drive
with propellers. The outer propeller is a left hand; the
inner propeller is right hand.
Notice how the tip of the blade on the outer propeller
travels down and to the left. The tip of the inner propeller
travels down and to the right. The same holds true for
propellers when you lay them down. This is one way to
identify propeller rotation.
Advantages of featuring dual rotating propellers on the
drive unit is more efficiency and less steering torque.
