Blade Search
 

I'm looking for a pair of 4 blade 21P Lt & Rt for Bravo 1's. Anyone got a set lying around. I've decided to Build new motors but I'm going to wait and run these one more season. I have stock 330HP 7.4's in an old big heavy boat. I have Mirage 21P's now and out of the hole they blow out a little. you really have to ease into it. but at wide open I'm only getting 4200. I'm looking for a little more bite out of the hole and a little better mid-range cruising speed. I figured keeping the same pitch and going to a 4 blade would do it for me this year.

You need less pitch and more RPM's, especially when adding a blade. Bravo 1 4 blades come in even pitches and the smallest is a 22.

I have seen other Stainless props in 19, 20 & 21P Just not sure what to try.

Post this in the prop section for some advice from BBlades.
