Mercury Lower Unit 1980-1986 35 40 45 50 60 70 HP

This lower unit is also interchangeable with the 1971-1979 40-70 HP Engines but this model has square cavitation plate and the 1971-1979 has the round. This unit will not fit the newer 90s model 3 Cylinder 50-60 HP Engines as they have a bigger gearcase. This lower unit was removed from a freshwater engine. The cavitation plate and skeg are in good condition. The paint on the skeg is rough but overall its ingreat condition but does have some scratches here and there as any used part would. The driveshaft spline count is11and the length of the driveshaft is 21 1/4". The spline count on the propeller shaft is13. This unit was drained and is free of any metal or water in the gear housing. The unit was pressure tested and is in need of a drive shaft reseal. The unit was also tested to make sure it was shifting in and out of gear properly and it is.
