Did you just put to stock quad IV's on it or did you have any lab work done?

Hydro Quad IV
 

I just took them out of the box and put them on,big improvement over the mirage.

What did they cost you new from hydromotive?

How much of a difference is there between a hydro and a bravo 1 4 blade?

Hydro Quad IV props
 

I bought the Hydromotive props back around '93 or '94.I think at the time they were about 400 each. I don't know what they cost now.I cant 't tell you the difference between Hydro's vs Bravo ones as I never had both on the same boat to compare.I had Hydro's on my 272 and Bravo ones on my 311.What I can say is both Formulas were much better with the 4 blade props than with the Mirages

The Hydro Quad IV's are $595 each from Hydromotive.

Looking at a pair of 24p Bravo Ones.....what is the difference between these and the hydros?

got the 24p Bravo 1's and the 4 blades do make a huge difference. Better handling, easier planing, and the top end loss wasn't to bad.
