Looking for some help on what prop I should be looking at for overal good performance. My boat is a Rinker 232, 4200 pounds dry, with a non vortec 5.7 2 barrel carb, alpha 1 Gen 2 with 1.62 gears. I have ran the boat one season now, and I think I am leaving some performance on the table. I am running a 19p 4 blade solas, max RPM is around 4100 WOT, at typically 38mph ish. I spoke with a person with the same boat and prop who changed his carb to a 4 barrel and can hit upper 40?s no problem. I do plan on doing a carb swap to a 1409 this winter. Question is I know 1.62 gears are typically not in 5.7 mercs. Are the gears going to hold me back that much once I do a 4 barrel? Should I be trying a different pitch based on my gears? Motor has healthy compression across all 8 cylinders too. Thanks for your time!
