I picked up a carryover Lund Impact 1775 w/ Mercury 115 Pro XS. I really like the boat it handles waves like a champ for a 1775 but the dealer definitely rigged it with the wrong prop. It currently has a Merc Spitfire 4 blade 12.5" 19pitch but according to the prop selector program on mercury's site I should be running a 13-13.5" 17pitch prop. Anybody out there with experience have any prop suggestions as far as best performance vs cost?
