ACME Harmonic Prop Puller The Harmonic Prop Pullers are designed for a variety of shaft sizes from 1" to 2 1/2". Please note: There are two possible prop end, thread size options for 1 1/4" diameter shafts on inboard wake/ski boats (e.g., Malibu, Axis, Centurion, Supreme, Tige, ATX, Pavati) will likely have a 3/4-10 thread size instead of the standard 7/8-9 thread size. If your inboard wake/ski boat has a 1 ¼” diameter propeller shaft, the thread size of the shaft should be verified, because it impacts choice of prop nuts, prop nut kits and Harmonic pullers. Acme Part #5005 is a Harmonic Prop Puller with a 3/4-10 thread size (this puller is commonly used on 1”, 1 1/8” and some 1 ¼” diameter shafts which have the non-standard ¾-10 thread size)Acme Part #5018 is a Harmonic Prop Puller with a 7/8-9 thread size (this puller is commonly used on 1 ¼” shafts with the standard 7/8-9 thread size e.g., Nautique, MB Sports) If your wake/ski boat has a 1 1/4" shaft, it is important to verify the thread size at the propeller end of the shaft. You may need the 1 1/4" Special Nut Kit (#5266MAL), or the non-standard nut, part #5003, or the non-standard 5005 Harmonic Prop Puller.
