greetings fellow Donzi owners

I just bought a used 23 ZF with 225 Opti and 4 blade prop

She is running good but is a little slow to get on plane and I think WOT is 45 MPH at 5300 rpms

A buddy of mine thinks I may be over propped

Most Donzis I see with outboards have 4 blade props on them. Is this to give more bite in the turbulence caused by stepped hull or ??

Thanks for any help.
