I just recently got the older SR2 with the same LIMA generator.
You will be getting one of the finest, most adaptable generators ever made.
Known as a 12 wire generator, you can set it up for 120/240 single phase power for your home, or three phase 208 or 416? for a shop. The 208 3 phase will power dual rated 440/208 three phase motors, and also give 120V per leg for lights and wall sockets without the need of a stepdown transformer. Very popular on small ships. The 416 could mean the leg voltage is compatible with 220 'mains' outside of the USA?
I believe it is a two bearing generator, so if the Lister packs it up, the generator could be saved and used with an other prime mover.
If the price is right.....GRAB IT!
