2004 2005 & UP Mercury Optimax 20" Lower Unit 75 90 115 HP 2.07 1 YEAR WARRANTY

This lower unit has a 2.07 to 1 ratio. As seen in the pictures, this lower unit does not come with the trim tab, the propeller, or the propeller hardware. We have taken the time to professionally strip and prime this lower unit, so it will be ready for a new paint job. There is some pitting around the housing and on the bearing carrier, but nothing that will affect performance. During our inspection, we did notice a tiny chip of the of the skeg and the cavitation plate, but this is purely cosmetic. We must note that upon inspection, the internal parts are in great working condition! Please note that we do not ship our lower units with oil. Upon receipt of the unit, this will have to be added before use.

Driveshaft measures approximately: 20-7/8"
