GEARCASE
PROPELLER SERVICE
When selecting a propeller, consider the following:
•
Use an accurate tachometer to determine the
engine’s full-throttle RPM.
•
The outboard should be trimmed for top speed.
•
Select a propeller that suits the customer’s
application and allows the engine to run near
the midpoint of the full-throttle operating range
when the boat has a normal load.
•
Occasionally, one propeller will not cover a wide
range of boat applications — water skiing to
high speed performance boating. In such cases,
it might be necessary to have a propeller for
each situation.
•
Refer to the Evinrude/Johnson Genuine Parts
and Accessories Catalog for propeller styles
and sizes.
•
Right-hand propellers are considered standard
rotation propellers. When propelling a boat for-
ward, the propeller rotates in a right-hand
(clockwise) direction as viewed from the rear.
•
Left-hand propellers are considered counter-
rotation propellers. When propelling a boat for-
ward, the propeller rotates in a left-hand (coun-
terclockwise) direction as viewed from the rear.
Propeller Hardware Installation
IMPORTANT:
Depending on propeller style, dif-
ferent thrust bushings, spacers, and cotter pin
keepers are used. See the
Evinrude/Johnson
Genuine Parts and Accessories Catalog for cor-
rect propeller hardware.
Apply Triple Guard grease to the entire propeller
shaft before installing the propeller.
Install thrust bushing onto propeller shaft with
taper of bushing matching taper of shaft.
If installing a propeller with an interchangeable
hub, assemble the propeller following instructions
provided with the propeller.
Align splines of propeller and shaft. Push propeller
until seated on the thrust bushing.
Install the spacer over the propeller shaft splines.
Wedge a block of wood between propeller blade
and the anti-ventilation plate.
Install the propeller nut and tighten to a torque of:
•
With Keeper – 70 to 80 ft. lbs. (95 to 109 N·m)
•
Without Keeper – 120 to 144 in. lbs. (13.6 to
16.3 N·m)
