Assuming your current prop puts you in the desired max RPM range, you will definitely need to reduce the pitch when going to a Stainless Steel prop and a 4 blade prop.

Usually, when going from Aluminum to SS, you need to reduce pitch by 1-2. Then, when going from 3 blade to 4 blade, you also need to drop 1-2 pitch. So, if you're planning to do both in switching to SS and going from 3 to 4 blades, you definitely need a 19p or possibly an 18p.
