1999 31 open props?

[Lafobrian@gmail.com]

1999 31 with 7.4 crusaders. I have 3 blade props and cruise along at 3300rpm doing about 21 knots. I see some guys with 3 blade and others with 4 blade. Would 4 blades increase my speed? The boat handles perfectly around the dock now with 3 blades but would that possibly improve as well? Curious

4 blades generally reduce top speed but also help get boats on plane faster and may provide some stern lift while underway.
