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 were in excellent condition. There are scuffs and scratches in the paint, but this is very common in lower units. This does not come with the trim tab, propeller, or propeller hardware.  Upon our inspection, we did notice that the skeg has a slight bend, and holes drilled in it for a stablizer. There is also some minor chips, but this will not affect the overall performance. The unit has been drained of oil and this will need to be added prior to installation. Purcahse with confidence!

Driveshaft measures - 22-1/8" from top of water pump housing to top of the pin of the driveshaft.
Driveshaft spline count - 8
Prop shaft spline count - 15
