Need Prop Advise for SBC 383

[riverrat77]

River Rat,

I have the 72" WT on 2 different boats, 4 & 6 cylinder aviation direct drives, it is comparable to the Q (both 10-1/2" blades) and will perform well for your application. But, in your original post you talked about snap and speed. If you want to keep some snap, the WT narrow would be a better choice and would plane the boat out faster. The difference in speed might be a handful of mph either way.

Myself, I am way more disappointed if I get stuck somewhere vs. being the fastest through, so I would go with the wider blade.

Thanks for the info and I just ordered a 72" Whirlwind Narrow im wanting more low end push.

Have you purchased a new prop already? I have a 2blade 72" whisper tip. I'm looking to go to a 4 blade. Due to adding a turbo to my smallblock

What set up how did that work out thinking of doin that also to my 6.0
