When selecting a propeller, consider the following:
• Use an accurat e t achometer t o determine the
engine’s full-throttle RPM.
• The outboard should be trimmed for top speed.
• Select a prop eller that suits the customer’s
application an d allows the engine to run n ear
the mid point of th e full-throttle opera ting ran ge
when the boat has a normal load.
• Occasionally, one propeller will not cover a wide
range of boat application s — water skiing to
high speed performance boating. In such cases,
it might be necessary to have a p ropeller for
each situation.
• Refer to the Evinrude/Johnson Genuine Parts
and Accessories Catalog for p ropeller style s
and sizes.
• Right-hand p ropellers a re considered standard
rotation propellers. When propelling a boa t for-
ward, the propeller rot ates in a right-hand
(clockwise) direction as viewed from the rear.
• Left-hand pro pellers are considered cou nter-
rotation propellers. When propelling a boa t for-
ward, the propeller rotates in a left-hand (coun-
terclockwise) direction as viewed from the rear.
