1980-89 Mercury 20" Lower Unit 90 115 150 HP Inline 6 2.0:1 Ratio 1 YEAR WTY!

This Mercury lower unit was removed from a freshwater engine and is in great condition. There are some scuffs and scratches in the paint, but this is common amongst used parts. There are 8 splines on the driveshaft and 15 on the propeller shaft. All the splines are in great condition and are not damaged in any way. This does not come with the trim tab. There are pre-drilled holes in the cavitation plate for a planing fin. From the base of the water pump to the top, the driveshaft measures approximately 20.25" long.  Please not that the cavitation plate has been welded, please see pictures. We cannot ship our lower units with oil in them and the unit has been drained. This will need to be added prior to installation. Purchase with confidence!
