Mercury 20" 1991-2006 Lower Unit 50 55 60 HP 3 Cylinder 2 Stroke 1 YR WARRANTY

This lower unit is in excellent condition. From the top of the water pump to the end of the driveshaft, it measures approximately 20-9/10" long and has 11 splines. The spline count on the propeller shaft is 13. All of the splines are in great condition with just slight wear on the driveshaft splines. When we opened this lower unit the gears looked great. The clutch had just some slight wear. The units oil was clean and free of metal and water. The shafts are straight and shift/turn smoothly with no binding.  We installed a new impeller and this unit was resealed and pressured checked. There are only very minor cosmetic flaws in the paint, such as scuffs and scratches, but this is purely cosmetic. Please note that this lower unit does not come with the trim tab, the propeller or the propeller hardware. 

Please remember to add oil before use.
