A question from an on-looker. Why are you so dead set on running that prop? If something else might work better, why not try it? Just a thought.

I am running 85-86mph GPS right now on 4lbs of boost fully loaded with fuel, coolers and 4 people. I run Bravo XRs (1.50) and 32P Bravo 1 props. I could put the smaller pulleys on and go up to 7-8lbs of boost but I want to see if some shorties would give me 6-8 mph.

I am propably going to add some IMCO nose cones next month and see what if anything I will get from them.

The nose cones are much cheaper ($250 vs $9K) route than me getting the the shorties.

The prop feels great on the boat, also its paid for. Cruise speed is about right, good mid. Why the 5B, well I hope will a shortie it will give a nice rooster tail. Yes its cheesy, but my 6y old thinks its the coolest thing on earth. Being superdad is hard, shooting a rooster tail is EZ!!

But you are superdad and enjoy it and you know what is important YOU THE MAN

Thanks for the Props! lol get it "Props" Haha

Thanks Again

Results????

Depending on the original x dimension, -2 shorties will make a huge difference in most applications. I saw a dramatic increase in speed partially because my drives were so deep.

My friend tried a 2 inch shorty on his 91 non step 27 fever. It was a 509 and had heads,cam,single plane intake,cmi's it did 75 -76 mph added the shorty and did nothing just jacked up the slip numbers and added rpm no speed gain.Before the motor up grades it ran 67-68 .

Yellow Fever, any results from the -2 shorties yet?
