prop puller-shoreham by sea?

boat safely laid up at shoreham and now trying to get prop off - at last managed to get blades off and prop nut off yesterday but prop hub not keen to come off shaft- hoping ideally to beg or borrow a prop puller or if not has anyone got a piccy of one so I can make one up or is there another way of freeing off the prop ?

prop first then cutlass bearing !
 
Re: prop puller-shoreham by sea?

Can't find a pic just now, but a self-built prop puller is basically two identical triangular plates (as thick as you can make them, at least 5 mm). On the middle of one side of one of these, a slot is cut so it slides over the shaft behind the prop. The end of the slot should be dead center of the triangular plate. Then drill three holes, one in each corner of the plates for 12 mm bolts (minimum size) . Get looong bolts, these go in the plate behind the prop, and the other plate fits on the shaft end. Put on the nuts, and tighten evenly.
A bit safer than the spider-legged pullers, who tend to fly in your face when they decide to slide of the prop core. Heating with a blowtorch helps, but not a good idea on a maxprop .

I had this precise tool made by Tony Woods Engineering of Harwich, who took all of two hours to finish it, from me arriving with cardboard templates to the finished item. Ordinary hub pullers would not work for me as there is only a small gap of about 7mm between cutless bearing and prop hub. These simple plates work just fine.

Word of warning. Do not be tempted to try a 3 legged puller on a 2 blade prop, there is a possibility you will bend the threaded section of the shaft.

The design suggested by Thalassa seems a good one. I have never had any luck with spider pullers. If the prop is removed, upending the shaft and bringing it hard down on a solid surface often does the trick (keep the loose nut on, to protect the thread).

I have a Gori 2 blade on my boat.
I spoke to the UK supplier at the boat show.

He said to put the pivot pins back in once you have removed the blades and the retaining bolt, put a metal bar behind the pins with a threaded hole then insert a long bolt on to the end of the prop shaft and off it should come.

I haven't tried it yet but must get on with it as the cutless bearing in the P bracket needs changing.

How did you get on removing the blades?
 
Re: prop puller-shoreham by sea?

Sometimes (?often?) the puller is not enough to start the hub off the shaft. One solution that has not yet failed is to tighten the puller as much as possible - if the legs slip, use a jubilee clip to hold them together - then give a smart tap to the end of the puller. If this doesn't work, see my signature!

If this doesnt work, then apply lots of heat to the hub, and repeat the above. So far I have never had to heat them though.

Clive G,

that sounds like a good idea - have managed today 2 borrow 2 different pullers which I shall try this weekend - removing the blades turned out to be easier than i expected - was advised by another member of my club to soak the grub screws with wd40 and plug holes with grease so that wd 40 trapped in and soaks in before trying to free off and glad to say it worked and was easy - even main nut came off straightforwardly but hub has won the battle so far - hence posting - once prop is of got to take it to see if teeth can be repaired where worn (certainly hope so as cost of new prop horrible) and then for the cutlass bearing! good luck
