This lower unit was removed from a freshwater engine and is in excellent condition. From the top of the water pump to the end of the driveshaft, it measures approximately 20-7/8" long and has 11 splines. The spline count on the propeller shaft is 13. All of the splines are in great condition. When we opened this lower unit the gears look exceptional. Please note that this lower unit does not come with the trim tab. There is some scuffs and scratches in the paint, but this is common amongst used parts.  Please remember to add oil before use. You can purchase this lower unit with confidence!
