[FONT="]I am looking at replacing/resizing my current prop. I purchased a 2013 Crownline 285 SS bowrider with 6.2L MPI Mercruiser 320 hp. This includes Bravo III drive with 2.2 gear ratio and Mercury 22.5 pitch duo props. The dry weight is 5600 lbs. and wide open throttle around 5000 rpms on light load. The current maximum MPG is 2.5 in the 25-35 mph range (10-14 GPH). How much could fuel performance improve increasing the prop pitch? What reasonable limit would prop pitch cause too much engine 'lugging'? Any other recommendations on prop sizing/fitting? Apologize if this is incorrect forum. Thanks, Allen[/FONT]
