prop help/recommendation

[dishwillow]

I have a 2002 VP 3.0 GSM with VP SX drive on a 2002 Glastron. The current prop, and the one that came on the boat, is an aluminum 14.8 X 75. WOT is 5000 - 5100 RPM.

By my understanding, I should be in the 4200-4600 RPM range. In order to get there, I should increase to a 19 inch prop. Am I understanding the mechanics correctly?

I do plan on upgrading to stainless. Anything else I should be considering?
