Would this pull my prop?

Cheers. I will check out the various sizes available of gear puller. however 100mm should be enough to fit between the blades of my current prop.
 
It will work but it can be a sod of a job if it hasn't been off for a while. Loosen the prop nut a few turns so when it does come off it won't drop on the deck and damage it's self. If it is stubborn then hit the end of the puller along the line of the shaft not the back of the prop or a tap on the side of the prop boss while the tension is on may loosen it. Some heat will help as well.
 
I would not like to bank on it but worth a try. At least it will not cost a lot. You generally need to put some heat into the hub as well, or try ringing it with two lump hammers; at this point the inexpensive puller often springs off.
A yard might have an hydraulic version.
If you take the propshaft out with prop attached, loosen the nut and wallop the thing down onto concrete like a pogo stick.
 
How big is your prop?

these are light duty pullers but OK for once a year use.

I have a 150mm version and so far its pulled props off shafts upto 35mm dia and drums off windlasses. The technique I employ is to fit the puller finger tight, then load it up with a couple of turns on the nut with a spanner, then leave it for a while with a strap round it. Then, whack the side of the prop boss with a couple of copper mallets and ping! off comes the prop. So far it hasnt been beaten - but there's always a first time . . . .

edit: dont remove the nut that holds the prop on, just loosen it a turn or two

hire

I'd hire a hydraulic pulley set, mine is a sykes picavant the great thing is the amount of possible configurations. Once you start hitting the prop you risk damage !

You need to hit it in order to jar it loose; a wallop with a copper or deadblow mallet will cause no damage. Most of the work is done by the puller, the wallop just starts everything moving.
 
They're only going to work on teeny props. I use a 10 tonne hydraulic puller and heat. (21" dia props)

Wind in a couple of tonnes and heat the hub boss. Fifteen minutes of that and off they pop. With a sound like a gunshot!!

As others have said, just back off the prop nut by a small amount (1mm of space between prop and nut) as this stops the prop flying off. If its close enough the puller should stay attached too.

You shouldn't need to whack em with anything - with the right puller you won't need to.

That said, if you really feel the need to bash em, use a deadblow hammer only.

Never had to use a puller. Slacken the nut off until its level with the end of the shaft (to protect the threads), heat the prop hub until hot to touch but not mad hot, with blowlamp and then hit the end of the shaft with lump hammer. Usually comess off easily at first blow.

Prop puller

I think OP will be disappointed with that puller. Best bet is to make a puller for the job. You need a flat plate of steel fairly thick a circle would be good about half the diameter of the prop. Drill a large hole in the middle and weld a big nut on the prop side. Get a bolt to suit. This presses onto the end of the shaft.
Now get 2 or 3 or 4 U bolts that will fit around the base of the blades. Drill holes in the plate for the U bolts. You can use long bolts and a plate across in lieu of u bolts. If you are concerned about strength of the blades make a pair of plates that will fit behind the boss with a hole between the plates for the shaft connected to the main plate by long bolts..
Clamp the plate via the u bolts to the prop and start tightening the centre bolt. Put some tension on it. Then try heat or bash or both. A puller is all about how it attaches. the U bolts will be the best grip on the prop compared to the lugs of the commercial puller. good luck olewill
 
I use a similar one with much longer legs and it works fine. I set it up and wind it up until it is under pressure, then set a blow lamp on the prop' hub and leave it until the prop' pops off. No violence involved, therefore no damage.
 
I've done it many times with a cheap three leg puller on different boats upto 34', both two and three bladed props, with no real problems. As well as all the tips above, I place a large metal jubilee clip round the legs to ensure that they do not pop off and also serves to hold it in place while tightening everything up. Use of gentle heat is also required.

Good luck and let us know how you get on.
