Mercury 26 Spline Conversion Shafts for Arneson ASD-8 Drives
Convert Your Arneson ASD-8 to Mercury & Hering Propellers
AS Manufacturing proudly offers our precision-engineered 26 spline conversion shafts for Arneson ASD-8 surface drives. These custom shafts convert the original 25 spline Rolla shaft to the more common Mercury 26 spline, allowing you to run Mercury and Hering propellers without replacing your drive.
With original 25 spline propellers becoming increasingly difficult to source, this conversion provides Arneson owners with a practical solution and access to a much wider selection of performance propellers.
Each shaft is precision CNC machined in-house at AS Manufacturing using premium 4340 alloy steel and professionally heat treated for exceptional strength, durability, and long service life.
