1-8 GENERAL INFORMATION
POWERHEAD DIRECTION OF ROTATION
This outboard motor is designed with a L.H. (left hand) rotation
powerhead utilizing an offset crankshaft.
This design has the advantage of reducing the size of the motor
and keeping the overall motor’s weight closer to the boat tran-
som and therefore closer to the boat C/G (center of gravity).
Rotation of the driveshaft is accomplished through a crankshaft
drive gear and a driveshaft driven gear.
These gears are located beneath the powerhead in the same oil
bath location as the camshaft chain.
As the rotational direction of the driven gear will be opposite of
the drive gear, a left-hand rotation powerhead design was
adopted to retain a conventional, standard rotation (right-hand)
propeller shaft output.
