I have a 28ZX with scorpions and they run great. 79 on GPS so far. What props were they running on the 292's? And what way did they spin.

Thanks

The 76 MPH is with 29" labbed Bravo One props.
Higher speeds with 30" labbed Bravo One props.
I think even 32" Bravo have been used but I am not sure ?
Props are spinning out.
Gear ratio 1.65:1

Personally I run std. 28" Bravo One props so I have great acceleration but lower top speed (72-75 MPH). I am considering trying higher pitch props, but I am afraid to loose mid range efficiency. Too high slippage in the cruising mid range and the fuel economy is gone, and the cost of gas here is app. 9.5 USD/gallon so I prefer low slippage

What props are you using ?

Sorry I missed this.

I run 25 mirage plus. 80.4 gps last run on lake michigan.

Trueser, what is the gear ratio of your drives?

1.5
