do i need to change props

[jvz33]

I recently purchased a donzi z33 w/ gen3 454s. I bought it in Michigan, where it ran every summer on 3 blade 23s. I take it to a freshwater lake Conroe here in tx. best rpms i can get out of it is around 4200. should I try 4 blade 22s my buddys got, or start over? Love my new restored cross bow ,just think shes not tuned up yet..

My guess is that you would be at almost the same RPMs with the 4 blade 22s. Bill

Thanks, I guess I just need more horsepower. I'm not sure what exactly she weighs,but its a heavy boat.. any ideas on newer plug in engines, maybe 502s?
