Yamaha 20" Lower Unit 4-Stroke Inline 4

Yamaha 20" 4-Stroke Inline 4 lower unit for 1999–2010 outboards, 75 80 90 100 HP. Inspected, serviced, and tested for proper function. Gears are replaced only if bad — good OEM gears are retained. Please note: All of the splines on the driveshaft and propeller shaft are in good condition, with little signs of wear. This lower unit does not come with the trim tab, propeller, or propeller hardware. Upon inspection, we did notice a little ding on the skeg, but this will not affect the overall performance. There is some scuffs and scratches in the paint on the unit, but this is entirely cosmetic.
