Prop Puller; Below you will find some of the popular devices for prop pulling
There are 2 main methods, harmonic and straight pull through a clamp of some design. The straight pullers start with the “C” puller which is really only useful for the smallest of props. They then get more complicated to handle larger diameters and larger number of blades.
Even the straight puller can use a smart bang with a hammer to move a stubborn prop. Some recommend heat but this can be unwise. The prop may be able to handle it but anything close by like shaft glans, strut bearings may get damaged.

Acme Harmonic puller
The cheapest puller on the market. $40
This prop puller is affordable, easy to use, and effective. Works by screwing puller on to end of shaft and hitting the puller with a hammer. The vibrations the puller causes the prop to back off. Great to put in your weekend tool kit.
Hitting the Harmonic puller vibrates the shaft so loosening the prop, see video of a inboard with traditional shaft. Tighten the puller all the way then back it off 1/4 turn. It will back off more as you hit it and it vibrates. Use a heavy metal hammer 5 or 9lb.
C Clamp puller
Simple C clamp type of puller, works well for small props. There are many versions of this type on the market. Simple screwing on the handle tightens the clamp pulling the prop off the shaft. Sometimes a smart hit with a hammer will loosen a stuck prop.
For larger props the clamp may not get around the blades so you need a puller like the ones below.
Pro-Pull 1″-2″ Versatile Prop Puller
The scissor puller is very versatile with the pivot pins, but is expensive at $300 plus. See video below of this type in use underwater.
PRO-PULL Versatile propeller puller is designed to remove 2, 3, most 4 and some 5 blade propellers on inboard shafts ranging from 3/4” – 2.” It’s made of high strength heat-treated alloy steel and finished with
cadmium for protection. The threaded rods, pivot pins and handle are manufactured using the finest stress proof steels available. The shaft end of the puller has a recess to captivate and hold the propeller shaft in the center of the tool so it can’t slip off while in use. The offset design of the pivot pins keep the hook of the tool on the propeller hub and pulls through the center of the propeller shaft. Minimal clearance between the propeller hub and strut are required due to the unique puller design. This propeller puller requires no additional tools for operation.

Propeller pages from Australia has some interesting and informative information regarding props, including how to measure the pitch of your prop.
If you find the prop is turning while trying to loosen or tighten the nut, place wood between hull and prop.
