Our Prop Nut Kits includes one nylon lock nut, cotter pin, and key. Available for shaft sizes 1" to 1 1/8" or 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. 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). Show more
