Fits 1" - 1-1/8" And 1-1/4" Shafts ACME 5008

ACME Prop Nut Kits include one nylon lock nut, cotter pin, and key.

Please note ONLY on the 1-1/4" Shafts that there are two possible prop nut options for 1 1/4" shaft sizes on inboard wake/ski boats.

For instance, the 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.

You may need the 1 1/4" Special Nut Kit (#5266MAL), or the non-standard nut, part #5003.

You can verify by measuring the overall diameter of your shaft threads (on the prop end). If your thread measures approximately .75" you require a 3/4-10 nut (#5003).

If your thread measures approximately .875 then you require a 7/8"-9 nut (#5023).
