There are online shops, with all sorts of Beneteau used parts, in France. They are cheap and ship.

And no one wants to venture a guess as to the right diameter and pitch to the prop without seeing the old one. Well, if I hadn't have lost the old one, I wouldn't need a new one!

I want to go sailing again. HELP!
can you help me do you think?

Have Arpege prop

I repowered my 1972 Dufour Arpege about 3 years ago and
have the original prop.
Do you want it.

lawsonmitchell OK. Here's where I stand. I've ordered the 25mm prop nut, lock washer, and anode from Beneteau. ($50.00) I've been advised they'll fit. When they arrive, I'll go swimming to confirm fit. If that works out, I've found a 12 x 8 LH with a 1 1/8 inch bore ($200.00) and a bronze reducer bushing ($86.00) to take the bore down to 25mm. If it all works (we'll see) then I'm back out sailing for $386.00. Less than an new prop, new shaft, new cutlass bearing, new stuffing box and new coupling... say $900.00-$1,000.00

Wish me luck!

On a vessel of that age, might he need these anyway ? I would think that loosing a prop, while the engine was running might have caused damage to these parts with the assoc. vibrations caused by a loose prop nut/prop.

75R20 Sounds to me like a used shaft in SAE (US demenisions) is your best way to go, as it will give you much more in options as far as props and hardware. It may not be what you want to do, but lets look at what went wrong in the first place;
1. You lost all the hardware that holds on the prop
2. The zinc is no longer attached ?
3a. The prop fell off while under way ?
3b. The prop is gone.
5. The prop shaft is damaged ?
6. The prop shaft threads are damaged ?

Buy a shaft and prop and move on, and perhaps increase your mantinence on the shaft/prop/zinc assembly in the future.
Good luck

tommays I made a call also and the issue is it does NOT pay for them to have a metric machine setup as its so rare for them

Fstbttms I just got off the phone with the manager of Bay Propeller, which is one of the largest prop repair facilities on the West Coast. He told me that metric-bore props are not something they sell! I am shocked. He said that you will likely not be able to find a new, metric-bore prop and that the bore reducer is the best way to go. I asked him about new nuts and he said they also would be hard to find, although they could fabricate something if push came to shove.

Well, I guess you learn something new every day. Maybe your best bet is to go with a larger standard prop and a bore reducer. Regarding the nut, you can buy the Beneteau prop nut and the zinc that goes on that. For additional protection, does sell limited clearance shaft zincs that will fit in the very small length of exposed shaft your boat has.

lawsonmitchell Fast Bottoms,

You say, "There is no compelling reason to not use a prop designed to fit on your 25mm shaft." I agree. But no one I've talked to yet (about 30 different shops) knows where to get metric prop nuts. A couple are looking into it. And I can't find any online. Do you have any resources? Also, the anode will have to mount on the prop nut as there is only about 1/2 inch of exposed shaft available between where the prop ended and the stern tube begins.
