Replacement Yamaha Lower Unit Assemblies

The lower unit (or “foot”) of your outboard motor is the portion of the engine that sits below the surface of the water giving any motorized boat or outboard its momentum.

Bad outboard lower units can give the operator shifting issues, and other signs will include water in the gear lube, metallic particles on the drain screw magnet, clunking sounds when shifted, or the loss of the ability to shift into gears. The lower unit is cast with an aluminum alloy specifically developed to improve corrosion resistance, and it also has the strength and rigidity to withstand impacts with things like driftwood. If a part or component within the lower unit assembly isn't working or fails completely, you'll find yourself stranded on the water. Understanding how your lower unit works and how to service it is essential.
