Do I stay the same??

[FSTHUH]

Hello, I have 18ft Monterey boat with Alpha One Sterndrive. Boat came with a stock 23p prop. I was going to upgrade to a Revolution 4 Prop. Do i stay the same pitch or since this one will be four blade to I switch to a lower or higher pitch? Thanks

Generally they suggest dropping one inch going to a 4 blade.
It would help to know your present max rpm and speed.
What are you trying to improve?
