Mercury 1976-1988 20" Lower Unit V6 135 150 HP 2:1 Ratio 1 YEAR WARRANTY! OEM!!!

This lower unit does have a 2:1 gear ratio and was removed from a freshwater engine. When we opened this up, we noticed that the gears look almost brand new. There are scuffs and scratches in the paint, but this is very common in lower units. This does not come with the trim tab. From the top of the water pump to the end of the preload pin, it measures approximately 22-1/8" long and has 8 splines. There are 15 splines on the propeller shaft. Upon inspection, we did notice some minor tooling marks on the prop shaft, but is still fully functional. Please see pictures. There are some dings around the edge of the skeg, but nothing that will affect performance. The unit has been drained of oil and this will need to be added prior to installation. Purcahse with confidence!
