Need prop advice for a 1995 380 Avenger
 

Hello looking to move to at least a 4 blade prop on my 1995 Avenger with stock 502s. Anyone have any test information or suggestions on upgrading to new props on this boat? Any information would be great, have heard of many people using different pitched prop set ups but all so different I am not quite sure where to start, thanks in advance for any help.
