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!
