The Mercury bravo one 4 blade 28 or 30 should be a good place to start testing . Better handling and cruise as well as lower slip numbers may be obtained .Depends on the RPM your engine needs to run for max hp for your pitch selection .

No harm in trying a 4 blade, but IMO you will want to stay with a 3 blade as 4s tend to manhandle light boats at times and given your delta pad bottom, it may be hard to keep it balanced on the pad with a 4. As to pitch, it was already stated that it is going to depend on your desired/intended rpm range.
