1970-79 Mercury 20" Lower Unit 90 115 125 140 150 HP Inline 6 FOR PARTS/REPAIR

This does have cosmetic flaws in the paint, such as scratches and scuffs. This does not come with the trim tab. The driveshaft measures 20-3/4" from the top of the water pump to the end of the shaft, making this a long shaft. There are 15 splines on the propeller shaft and 8 splines on the driveshaft. The shafts on the unit are straight. We did perform a pressure check on this, and everything held. We still reccomend that this lower unit have a new seal kit and impeller installed. Please note that there are some chips out of the cavitation plate, as well as the skeg. It does shift in and out of gear smoothly.

Due to shipping restrictions, lower unit are shipped without gear oil, please add before use. Purchase with confidence! 

Because we have this listed for parts or repair only, we virtually cannot accept returns on this lower unit. Please confirm closely that this is the correct one for your motor prior to purchasing.
