I own a 23 regulator with a f225 Yamaha.The Yamaha Saltwater Series prop 15 1/4 * 17 tops out at 6000 rpm,right where I want it but its a heavy boat and basically underpowered in my opinion.I need more hole shot/midrange cruise and would like to try a 4 blade Merc Rev 4 blade but I am confused about the correct pitch?Should I go with the 15 pitch or 17 pitch?The Rev 4 balde is 14.6 diameter(smaller)Iwant to try my best to keep wot at 6000 and Im willing to sacrifice a little top end.If anyone with the same or similar boat has any info it would be a great help,thanks
