8839A2 7574A2 6642A2 Mercury 1972-1990 Crankshaft 50 60 65 70 HP 3 cyl POLISHED!

Every crankshaft that passes through here is given a multi-step process to guarantee it to be in good, working condition. We’ve spent many hours perfecting this process to ensure that the crankshaft in this listing is essentially flawless:

• Journals, Mains, and Bearing Surfaces have been professionally cleaned, polished and inspected
• Rust-Free!
• Splines are not damaged in any way
• Threads are not stripped or worn
• Corrosion inhibited to protect it for years to come

Upon our inspection, we did notice that the lower bearing surface does show some bearing marks, but this will not affect the overall performance. 

Please note that we will not accept returns for this item. Please be absolutely sure this is the correct one for your motor prior to purchasing.

We have provided this cross-reference with the resources we have available in regards to fitment. This most likely will not fit every model for the years and horsepowers we have listed. We urge you to make sure this is the exact item you need by matching the part number to what is required for your motor. If you need help doing so, please contact us prior to purchasing and we would be happy to help!
