Nonsense. Most pullers need a sharp blow to jar the prop loose anyway.
Would this pull my prop?

I used a similar puller on a fixed 2 blade prop on a 1 inch shaft and spent half an hour heating, whacking and winding scary amounts of pressure on - nothing happened. I came back next morning to find the puller hanging at a jaunty angle and the prop backed off against the nut. I assume the heat had finally reached the joint, or else the prop fairies had been in overnight! I guess the moral is to be persistent and don't let the frustration make you do anything too rash, it will come.

One potential problem is the distance between prop and cutless bearing housing - on some boats, like mine, there is only a very small gap, and the legs of a Screwfix puller won't fit in the gap without being ground to fit.

I'll stick my neck out here, I would always jack off a prop rather than use a puller, I would never hit the prop hub, possibly the shaft end but in practice by jacking props I've never had to. Heat can help but a a jack can easily exert enough force to pull off a prop.
A simple rigid bar/box section, drill and tap two holes in the rear of the prop hub, screw in threaded rods, either use bar against shaft end or a short fat bolt threaded through bar to push on shaft end. It's gentle, can't slip, can't damage the prop and also works if you have a cutter fitted. It can be used for any number of prop blades. Heat the rear of the prop hub to around 100C and that will normally seperate it from the shaft to make it even easier.
