The Sierra 118-4249 is a precision-engineered lower unit drain screw designed specifically for Johnson/Evinrude E-Tec outboard motors. This essential maintenance component features an integrated magnet that captures ferrous metal particles suspended in the gear oil, helping to protect your lower unit from premature wear.

Key Features:

• Built-in magnet captures metal debris and contaminants from gear oil
• Allen head design for secure installation and easy removal
• Precision-manufactured to meet OEM specifications for reliable performance
• Direct replacement for OEM part number 318544

This drain screw is compatible with all Johnson/Evinrude E-Tec outboard motors and OMC stern drive applications. The magnetic tip provides an additional layer of protection by trapping metallic particles before they can circulate through your lower unit, making oil changes more effective at removing harmful contaminants. Interchangeable with Johnson/Evinrude 318544, Mallory 9-72660, and OMC 318544/912624.
