Yamaha Replacement - LF250 Counter Lower Units

Yamaha LF250 Counter-Rotation Replacement Lower Units

Marine Parts Co. supplies direct-fit replacement lower units for Yamaha LF250 counter-rotation outboards. These units are designed to replace LF250 models equipped with dual water intakes as well as early LF250 units with side water intakes. Each lower features a water-cooled bearing carrier for added durability and consistent cooling performance, making them a dependable choice for long-term use.

The units are finished in black for a clean, universal look, but can be painted to match your engine if desired. Built to OEM specifications for counter-rotation applications only, these replacements ensure strength, reliability, and an exact fit to keep your Yamaha running at peak performance.
