The adjustable type engine mounts permit
adjustment sideways as well as vertically. Vertical
adjustment nuts lock up or down on the threaded
vertical stud, with a slot provided to allow side to
side adjustment on the engine.
IMPORTANT: The large adjustment locknuts on
these mounts must be tightened properly to
retain alignment. It is also advisable to spray a
protective coating on the studs and nuts to
prevent corrosion.

EDUCTION
A reduction gear reduces the rotating speed of the
propeller shaft in relation to the engine RPM. This permits
the use of a larger propeller while allowing the engine to
attain its rated RPM, thereby increasing efficiency.

The reverse gear incorporates the clutch and
controls the rotation of the propeller. The position
of the clutch control or shifting lever indicates the
motion which the clutch and reverse gear are
transmitting. The center position of the lever
indicates neutral. Engine RPM should never
exceed 1000 when engaging or disengaging the
clutch. Higher RPM will result in unnecessary
wear and shortened life of the unit, and perhaps
breakage.
Marine reverse gears are hydraulically operated,
thereby making it imperative to periodically maintain
and check oil level. If the correct oil level is not
maintained, slippage occurs, causing damage to
the clutch plates. Too much oil will cause foaming
and erratic clutch operation. For additional
information see the Engine Operator's Manual.
