Help Needed: Boat: 2013 22 SSX with sea legs, 115 Yamaha 4-stroke, and 25 inch toons Prop: Came with 13 pitch Yamaha aluminum. It was hitting the rev limiter and the GPS speed was 20mph Switched to a 15 pitch. Hit 5950 rpm at 22.5 mph Thinking of trying a 17 pitch. Any predictions or recommendations? My dealer says the 17 will slow it down. I was hoping to get 27-28 mph. I know the sea legs will slow it down. I just want maximum efficiency, etc.
