421-5275 Mercury 1974-1985 Crankshaft W/ Bearings 7.5 (75) 9.8 (110) HP POLISHED

• All crankshafts are professionally polished and inspected.
• We now use a 2 step process to clean and polish these crankshafts, including hand polishing and powder blasting. This helps in the inspection of the journals and bearing surfaces.  
• We take pride in selling parts that are like new and in great usable condition.  

• This crank does have some slight pitting on the drive end.  This will not affect the performance of this part.  
• There is no scoring on the journals or bearing surfaces.  
• The splines in the drive end show no signs of wear.  
• The threads on the flywheel end are in great condition as well.
• This crank does come with the Main Bearing Assembly (1938A6) and the Upper Ball Bearing (20861).
