Hi I have a Fountain lightning 42, 2006 with+ 700sci and bravos thinking about changing to the bravo/arnesson kits!
Anybody have the experience at this settup????

It's been done - works.

It would be a nice package , There is a 12 meter around in my area that came with arnesons on it . I put the conversions on my 35 and it solved all my drive breakage problems

700's/Bravos?! I assume the boat came with 600's/Bravos and you have the Whipple upgrade?

Yes i bought it like this 800hp and i running Teague upper and Imco -1 with maximus 34 props 106mph so the combinaition is not ideal! for the drives...................

As said, its been done. I wouldn't assume it is a simple bolt on. Have seen some have to modify the notch to get the boxes low enough.

Out of all the conversions I have seen the only ones that had to have the notch modified were in staggered boats

I had to have the notch filled on mine - as would an 06 stagger. It was well worth it IMO. Cruising around in washing machine slop and launching without the slightest worry of grenadeing my drives makes it well worth it IMO, especially if you can pick up a slightly used set at half price like I did on mine.

i personally would do a #6 conversion. A nxt transom assy would keep your engines where they are. Boat would be faster also.

let me know if you go selling your current drives...might be interested in one :-)
