Who has or had a 38 with 700s w 6 drives what props are you using @ what speeds ?

I had an 08 and it ran 122 plus with 39 pitch 6 blade Herrings. It had a stage two Whipple mod and Brian Forehand did the bottom. Also 1:50 ratio.

122! That is moving, nice set-up

What about stock setup props ? I have 17.25 36 15 r 5 blade and hits the limiter about 90 .

With the same 39 pitch props it ran 114. I think that it was turning around 5300 or so rpm's.

Still 6 blade ? did you have vent tubes ? thats quite a bit of difference from mine .

It was with the 6 blades and it did have vent tubes. You probably know but the vent tubes do not help the speed. The boat was also no speed demon getting on plane.

Mine does not have vent tube I would most likely have to put them on with 6 blades. Do you remember prop diameter , rake , rake ect Hering or Merc ?

17.25 diameter, 16 degree rake, 6 blade Herrings. They came on the boat from the Factory

Thanks for the info ARB .
