MnPat1, can you tell me about the 17 P Revolution 4 prop? I was considering purchasing that prop but as it wasn’t recommended in the mercury prop selector I wasn’t sure if it was a wise purchase. I have a aluminum 19 p and am running 5520 rpm at WOT @ 47 mph. Dont mind losing speed as long as it isn’t greater than 5 mph. I’m going for better boat control in rough waters near piers and also better hole shot and bite at lower speeds in turns when taking the kids tubing
