2006 & UP Mercury 20" Lower Unit 40 50 60 HP 4S BIGFOOT 2.33:1 EFI 1 YEAR WTY

This lower unit has a 2.33 to 1 ratio. As seen in the pictures, this lower unit does come with the zinc anode and trim tab. This does not come with the propeller or the propeller hardware. There are some scuffs, scratches, and missing paint, but nothing that will affect the overall performance as it is purely cosmetic. The skeg is straight. There is a slight bend on the cavitation plate, but again this will not hurt anything. There are minor dings in the skeg, but is common with lower unit. 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. This will make a great replacement for your motor! Purchase with confidence!
