SCX or SCX-4

I have considered the NXT, however it is a lot of work to convert vs an SCX. Plus the NXT transmission is a weak link when you get over 700 hp, and if I had to guess, in stock form, the SCX is stronger. Yes you can replace the NXT transmission with the BAM conversion but that is $15k plus. If I could find a good deal on an NXT set up, I would consider it. As far as costs go, SCX-4 used maybe $22-23k. SCX uppers used- maybe $16K.
The Six is just too heavy. They only made a few 39 with 6's. The Bravo and NXT boats are better balanced. Plus with the Six, you would have to move the engines from a full stagger to a short stagger. There isn't room to run a full stagger. I want to keep the engine low in the boat, so anything with a velvet transmission is out. Otherwise, I would have installed the Arneson setup I had. That would clearly be the best option, but that is way too much work!
So the best option for this boat is, SCX or NXT. If I leave the engines as they are, maybe Bravos with Drive Guardians.

Gee thank you... Adding some transmissions isnt the end of the world as if its dual drive shaft, i would imagine you could shorten the drive shaft to accommodate the trans...

HA, it is far too easy to let these projects snowball out of control. The next thing you know, you have $100k wrapped up in your drive upgrade. When I looked at the boat, I knew the Bravos were coming off, but the upgrade had to be easy. Sure the ultimate set up might be 6s with NXT transom assemblies , and the BAM NXT transmission upgrade. However, when all is said and done, you would have an easy $100k into that.
I do appreciate the opinions, however, this needs to be a no glass work project.

The BAM trannies also add another 6-7” of set back I believe. That would have to be figured in your X dim then. And then you really have these drives with cleavers hanging out past the swim platform.

very rare for a v bottom to have 2 driveline setups vs 1 plug in and 1 driveline. I know the silver 39 gtx did but again it’s rare
