Sierra 118-4228 Prop Spacer for Johnson/Evinrude Outboard Motors

The Sierra 118-4228 is a splined aft propeller spacer designed for Johnson/Evinrude outboard motors. This essential propeller hardware component aligns and secures the propeller to the shaft, helping to maintain proper prop positioning when the inner hub loses its original shape.

Key Features:

• 13-tooth spline design works with tab washers to prevent nut loosening
• Nylon construction for durability in harsh marine environments
• Bears reverse thrust loads to prevent inner hub from sliding aft
• Large surface area provides superior alignment and load distribution
• Meets or exceeds OEM quality specifications

Compatibility:

• Johnson/Evinrude 40 HP (2 cyl) 1984-2005
• Johnson/Evinrude 48 HP 1987-1996
• Johnson/Evinrude 50 HP (2 cyl) 1975-2005
• Johnson/Evinrude 55 HP 1976-1979
• Johnson/Evinrude 65 HP (2 cyl) 1980-1985
• Johnson/Evinrude 75 HP (3 cyl) 1975-1985
• Johnson/Evinrude Sprint/Formula E 1986-1992

For optimal performance and propeller longevity, Sierra recommends removing and greasing the propeller spacer at least once or twice per year to prevent seizing.
