To Much Information .. But you asked Rich .. LOL
The CV16 hull was designed back in the 1960's, not sure by who.
By late 60's early 70's the copyright / patent was off and at least six Mfg. were using the hull design for there boats.
G/C, Sidewinder, Weindt, etc. all used this hull with different deck designs.
There is still an active group of Sidewinder owner, and some have problems with the outboard version cracking at the rear of inner chime.
Not sure if it's from bad design, bad glass layup or cracks easily when you hit something while running … or even a combination of all.
The box formed by the motor mounts on the CV16SS and V8 would be right at the weak spot on the outboard version and I haven't found any info on anyone having problems with it. Although I don't think any other company made an I/O version of this hull, and if they did, they didn't make to many.
Red line in below picture is where CV16 outboards crack inner chime.
Second picture shows where motor mount box would support hull in that location.
