Replacement prop nut.
3/4″ – 10 UNC fits shaft sizes 1″ to 1 1/8″
7/8″ – 9 UNC fits most shaft sizes 1 1/4″
Please note: There are two possible prop nut options for 1 1/4″ shaft sizes on inboard wake/ski boats (e.g. 2015 and newer Malibu, Axis, Centurion, Supreme, Tige, ATX) might have a 3/4-10 thread size instead of the standard 7/8-9 thread size.
If your wake/ski boat has a 1 1/4″ shaft, it is important to verify.
