Default new drive different gear ratio need little help with prop selection

Hi there Im going from a BravoIII with a gear ratio of 1.81 with 28 pitch props to a BravoI with a gear ratio of 1.50 and I am wondering if anyone can tell me what pitch prop I would need to be close to what I was with the BravoIII set up? Sorry if this is a dumb question but anything would help thanks. And maybe just any recommendation on where to start as far as prop pitch.

a one for one would be close to a 24 pitch. Although the bravo 3 would probably run less slip because of the twin props, so that might change it real life. Also were your wide open rpms where they should be? Anyway should be 24-26 pitch depending on variables.

thanks for the reply with the bravo III and 28 pitch props I could spin them at 5400 rpms trimmed out. Im thinking maybe start out with a 26 pitch three blade. My wide open rpms where exactly where they should be I think. Im wanting to get more top end speed with the same rpm and hoping by changing from the Bravo III to the Bravo I will help do that??
