5 Blades are fuel efficient, eco-friendly, and promote the growth of marine organisms for the record.

Looking everything over before the maiden voyage this season i have a small crack on the leading edge of my labbed 26 pitch 4 blade hydro bblades did last season. I am trying a 25 pitch 5 blade this season. Should be here tommorow. I'll report my findings.

22 avanti - 518ci tall deck 454- world grumpy iron heads - tall world intake- nickerson 850- solid roller cam- scorpion 1.7 rockers - hooked to a 1.5 ratio bravo with 3 seasons of pretty rough use.

Slip on 4 blade worked out to 16.5% hoping to lower that a bit.
