6 MONTH WTY 1994 & UP Mercury Force 20" Lower Unit 30 40 50 HP 2:1 Ratio

This lower unit was removed from a freshwater motor, is in excellent condition, and is ready for installation.  All you have to do is add oil! We took the time to professionally clean and inspect this item to give you confidence in your purchase. This unit spins and shifts smoothly with no binding and the prop shaft is straight.  The driveshaft splines are showing slight wear.  When drained of oil, it was clean and had no traces of water or metal.  The paint has been stripped off and a coat of primer applied so you can make it any color you want!  From the top of the water pump to the end, the driveshaft measures approximately 21-1/2" long and has a 14/13 spline count. All of the splines are in great shape and the skeg is not cracked or broken. This unit was pressure checked with a new impeller installed.  There are pre-drilled holes in the cavitation plate that will not affect performance.  We are offering a 6 MONTH WARRANTY on this lower unit with a core return so that you can purchase with confidence!
