77389A2 77393A1 Mercury 1976-1979 Long Driveshaft 40 50 70 HP 11/13 Splines OEM

To ensure that you are receiving a good quality part, we have taken the extra steps to guarantee this driveshaft to be in excellent, working condition:

• Professionally Cleaned & Inspected
• Shaft has been professionally inspected for straightness
• 11/13 Splines
• Approximate Total Length = 30-5/8" long
• From the top of the key way to the top of the shaft it measures approximately 21-3/4" long
• Bearing surfaces have been inspected and are in good condition
• Corrosion inhibited to protect against rust

As seen in the pictures, this does come with the bearing. It rolls smoothly just like it should. There are some scuffs and scratches on the shaft, primarily around the key way, but nothing that will affect performance. The splines show minimal wera and are fully functional.

Matched against the standards of our competitors who pull it out of an engine and throw it online, the driveshaft you receive from us, won’t even compare. Purchase this driveshaft with absolute confidence!

Please note that we will not accept returns for this item, if ordered incorrectly or you changed your mind. Please be absolutely sure this is the correct one for your motor prior to purchasing.
