I've got a 1972 18'3" Sutphen Gran Sport (very similar design to Donzi 18) and I need some help in selecting the proper prop. I've got an unusual engine/drive package, a Volvo/Penta AQ311, which is a 350ci small block with 307hp (stock power rating, but now features a a high-rise exhaust system), turning a Volvo 280 drive (long-shaft(?) with a hydromotive nose cone). I've got no starting point here, as the last prop was stolen...Any info would be great. Oh yeah, and if anyone has a 24 foot Donzi "Spitfire" they wish to sell... (C;
