Prop Question for 650MDG motors

bonecrusher · 06-12-2009, 01:37 PM

I have a 36' Spectre that I removed the blowers from and went back to manifold single 950hp carb.
It has 650 MDG motors, what props should I run, I have 5 blade 34's currently but that was with the 800+ hp.
Thanks for any input

you should run Bravo 1 - 4 blade 34" with 5/8" cut off the difuser, turning in.

34's for everyday running and 36's for that top number. Granted, you might try some other props like Hearings and see how they work.
