Onean Carver 1 board conversion to X ?!


I just bought a new Carver 1 for my kid, out of warranty. My Carver X is dead, send it to Onean for repair. Now I wonder what if I am going to install 2 jets on the Carver 1 to transform it in carver twin, 2 motors, 2.5KW each, 2 tubes, same invertor…or not.
First I need to check out how I disassemble it, not easy.
Any ideas how? What kind of motors does Carver 1 has? 2 on same shaft.
