Mercury 135 150 175 200 HP V6 1976 & Newer 20" Lower Unit 1.87 Ratio 6 MONTH WTY

This lower unit is in great condition and ready for install. From the base of the water pump to the end of the driveshaft, it measures approximately 21 3/4" long.  There are 8 splines on the driveshaft and 15 on the propeller shaft. All the splines are in perfect shape and are not damaged in any way. Please note that this does not come with the trim tab, propeller, or the propeller hardware. The paint is a little banged up, but this is entirely cosmetic. This will come exactly as pictured. Purchase with confidence!

We have drained the unit of oil and this will need to be added prior to installation.
