f302 formula 30ft with twin stock 454 330hp with trs drives. currently have 25p quicksilver on are these to big?

I think their too big. I had a 30 Scarab same combo and ran a 21P, 3 blade cleavers.

i think your right

I have a 33' Fountain, similar weight boat w/ same motor/drive combo. Came with 23P, now I have 25s. I went a little bigger to increase cruise speed, and I almost never hold it at WOT anyways. Pulls the 25s fine @ cruise, but only revs to 4500, trimmed to the max on a good day. The 1-2 MPH the 23s give me on top doesn't make it worth it to me for cruising, so I dont see myself putting them back on. Depends what you're looking for.

Long story short, I have a set of SS 23s available if you want em!

What is your RPM at WOT?
