Hi Madworm.
The Shockwave and SV27 are well known, the V24 is the most scale looking boat, but it has the same motor as the much smaller Arpro, the 3635 1520KV outrunner is way too small for this size boat.
Also a universal joint is not an item that should be used in a fast electric.
Basically, the hull is the only item of the V24 that could be used again; you'll need new hardware, a motor, ESC and Lipo(s).
As the V24 is one of the stunning looking Dragon boats it's also better to look at it rather than run it, specially with better hardware and a motor that will make it go 50 mph.
Reason for this is the brittle gelcoat with the softer glasscloth and vinylester layer underneath, just running the boat will cause hairline cracks in the surface...
As you're in the UK take a look here:

Keep in mind that fast electrics have few details for a reason, they simply fall off or get damaged while running the boat.
