Not sure if this will help but my 2007 214FS has an alloy 14.5 x 19 (rh) prop. The engin is a 270 hp Volvo 5.0 litre with SX outdrive. I have had 53 mph from it with 3 people on-board and half a tank. I was told by a good s/s prop vendor at a boat show that a stainless prop could give a further 5-10% improvement. There are several websites with prop pitch and size calculators. I have tried to get info from Volvo and Monterey. Volvo referred me to a dealer and Monterey haven't responded as far as I can see.
