2 bladed prop to 3 blades

[roger3645]

I'm running a 1975 merc 85 hp (Still runs good) it has a 19 pitch 2 bladed prop. I want to change it to a 3 bladed prop. I read somewhere when adding an additional blade you should drop the pitch down. If so, I should drop down to a 17 pitch prop. Does this sound right to anyone else?
