I would call a rigger or possibly Installer Marine, Bob. Someone who has set-up the 47's. As far as props go Hydro or Hering props would be great on the boat. I would run 5B or 6B props on her.

We have done numerous with Bravo 1 props and with Maximus 5 blades, also Herings.

What exactly are you asking? X dimension, pitch?

Thanks for your replies i have been away some days now.I need to now x dimension for good all round performance and cruising speed and also recommended propellers and pitch

Re: 47 lightning need to know prop and x dimension
 

For all around performance and good cruising, you can stay with the standard bravo drive cutouts. Fountain is pretty aggressive with their X dimensions anyway. You don't necessarily want shorty cases on this boat.

Using a set of Bravo 1 propellers in 28 or 30 inches of pitch will give you a good baseline and tell us which direction to go next. I think you will like those props but may opt to go to some 5 blades for better cruising speeds.

Northpole, the x-dimension for your hull should be 17.25x19x17.25 . It looks like this gave the best results for your hull. Call if I can answer any other questions, 252-975-7048 (Chris). I'll be glad to research any questions that you have.

It's always better to mount your drives a little too high than a little too low. Spacers, if required, are a lot cheaper than shorter lower units.
