Good overall used OEM condition with normal cosmetic wear consistent with previous freshwater marine use.

The housing appears structurally sound, and the skeg is intact with no obvious major impact damage visible. The cavitation plate appears straight.

The propeller shaft splines and input shaft splines appear to be in good condition, and the U-joint assembly rotates smoothly by hand.

Cosmetic condition includes normal scratches, scuffs, oxidation, staining, paint fading, and paint loss from age, removal, storage, and previous use.

As with any used sterndrive, we recommend inspecting and servicing the gear oil, seals, bearings, water pump, bellows, U-joints, and other normal wear components before installation.
