setting X drive height (#6 to Bravo conversion)
 

Hi Jo and fellow Pantera owners!

I've posted this in the technical forums and thougth a duplicate post here might work too. I'm re-rigging a Pantera and struggling a little as to where the drives heights should be.

I've read many posts on setting X dimension, but still having a hard time figuring out what to do for my specific application.

I'm planning on installing bravo drives(lwp) on my Pantera that was originally rigged with #6's. The engines are staggered and jack shafts will be used to connect to both drives. I'm planning on having an extension box made that will adapt the bravo to the #6 cutout on the transom.
The transom angle is 13.4 degree and the transom has a 10" deep notch on the bottom. The attached picture shows the current cutout for the #6 and the drives are on 18.5" centers.
Also the height of the notch at each drive center line is 7".

Now.... how would I determine the proper X dimension?

I'm sure I need to take into account the transom notch, but how does that affect it. I've also read that for each 12" the drives are set back the drive height can go up 1". Does the notch transom enable the extension box to be shorter in depth (ie. 6" vs 12")?
I can have the box fab'd to any depth as well as have it layout with a "neutral" setback if needed.

Anybody else ever go thru a conversion like this?

Looks heavy, you sure you want bravos on that thing?

I really have no other options that fit into the budget at this point.

Hey Pantera 38,

I will try calling you on Monday and talk to you about this set up.

Regards,

JO

The Bravos should have more reach than the #6 but will be closer to the transom as far as the prop location. I am not sure how much the #6 is shorter than the bravo. Jo will know or Mindi at dollar marine or Marc at BAM will know. If you are mounting them on boxes than you will want the propshafts close to the same depth as the #6's , if no boxes or setback than try the shafts about 2 - 3" deeper than the orig. #6 good luck, The Ironman.
