3 balde 21p ss vs. 4 blade 20 aluminum

[lilb]

I was wondering what to expect as far as performance difference between a Quicksilver 3 blade 21 p ss prop vs. 4 blade 20 p aluminum prop? Rite now it is a dog out of the hole and hits 48 mph on gps. Will the 4 blade prop give me a better hole shot with out losing mutch on the top end? Thanks

When changing material and design you pretty much eliminate any predictable results.
The 4 blade should improve hole shot,stay on plane easier,will likely handle better on plane and at the dock.You will lose top end.A guess at least 3mph.
