Hi, I could use some prop help please..I have a 1987 21z donzi 454 330hp with a alpha drive.The motor says its rated to go to 4600rpms..Currently i have a 19p Quiksliver clever 3 blade on it..Its goes 59mph( gps) at 4200 rpm. I would like to know what i should go with to get my rpms up and speed. I was thinking 19 mirage pluss or 17....any suggestions

I get the lower pitch part. But I guess a better question is will a 19 cleaver get me more or less rpm than say a 19 mirage Pluss. I have no props that I can test around here so I must buy one to try one So I would like to get close as possible thanks
