Mercury 1976-2005 LONG 20" Lower Unit V6 135 150 +HP 2:1 Ratio 6 MONTH WTY OEM

This lower unit does have a 2:1 gear ratio and was removed from a freshwater engine. The impeller looked new so it was not changed. There are scuffs, scratches, and chips in the paint, but this is very common in lower units. There is a minor chip out of the skeg, but this is purely cosmetic. This does not come with the trim tab, propeller, or propeller hardware. This will come exactly as pictured. This lower unit does have a 4-3/4" big bullet. The unit has been drained of oil and this will need to be added prior to installation. Purchase with confidence!

Driveshaft measures - 21-1/2" from top of water pump housing to top of driveshaft.
Driveshaft spline count - 8
Prop shaft spline count - 15
