Is anyone runnin a 6 blade on a 29' fountain ? If so let me know what your results are? I think it may create to much stern lift.

I agree with your assumptions, that would also seem to be really hard on the drive even if you didn't come out of the water.

I talked with the Herring guys at the Miami Boat Show and they felt that the 6 blades with 2 inch shorties would give me a significant speed increase over stock Bravos with four blades. I'm sure it would be harder on the drives. I think my outdrive guy might have some shorties that I can try out. I will post it if he does.

I heard that the new fountains are leaving the factory with herrings on them. I have an opportunity to pick up a new in the box 31 Herring 6 blade for 500 bucks..Just wondering if it would work on the 29 fountain without killing my Imco sc drive.

Does anyone know, what size hearing prop they are putting on them at the factory. I looking at playing with some props.I have a 29 with a 600sci with the ITS/SSM.

Herring props

I would just call Hering and ask them what they would recomend as a starting point.
