Prop Help

we put a B3 on the BatBoat to get out some of the torque from the B1. 400 hp 383. 1.5 ratio.

stock 24P cupped 71mph at 4900 RPMs, 71 mph at 5100 rpm's
Stock 26 cupped 71mph at 4400 RPM's
WOT should be 5400 rpm's

We have thought about some trimming on the front prop to cut some drag. I see that Ron Hill suggest a 26P "Afterburner" prop in front of a 24P prop due to the front one being in clean water.

Thoughts?

BBlades should be able to get you another 300rpms and 1-2mph on the top end.

Give us a call and we can discuss the options with the 24's.

On this boat I'd stay with the 3x3's.
