Sealey do a good 10 tonne hydraulic puller , I got one recently and found it very good. I think I'm right in saying that you can get a 30 tonne hydraulic puller but I suspect they will be fairly expensive. Sorry to point this out if you already know but you must resist the urge to go mad with the bar on the hydraulics or the seals will fail. It should be finger pressure only. ( Thats why I had to get a new one!)
Hope this helps.
Best to make your own to fit your own props.
Or have them made.
All that is required is a 2 flat plates, correctly cut and drilled, and 3 long bolts.
I have made prop pullers to fit all the boats I have had.
Ebay about £14. I used one to take my 28 inch prop' off after ten years.
Gently heat the boss with a blow lamp for about 15 minutes and it will pop' off nicely!
