i have a 1990 29ft fountain with twin 350s and alpha 1drives, vortec heads, comp cams, rpm intakes ,emi thuder exhaust .not sure how much hp now.i have mirage 25p props right now with 4 people and half tank fuel its running 4600rpm and the speedo reads 70.any suggestions for a better prop?

I havent run solo yet but the boat doesnt change with more people or gear .

I'd concider Lab Finishing the 25's if the boat planes easily.
Take the 250rpm and the speed that comes with it.

If you want better low end and mid range there are a few 4 blade props to choose from.

thanks for the reply think i will try that for next year as the props seem to be a good over all prop i just want some more top end.
