Re: Differences between Super Maramu (SM) and Super Maramu 2000 (SM2000; SM2k)
That's because there really is no one definitive list. Although there was a definitive name change to Super Maramu 2000, some of the design changes were made BEFORE the name change and some were made after. Throw in all the minor revisions made over the years, the engine changes, and the many different options offered by Amel (dive compressor, diesel heater, watermakers, comfort pack, etc.) and you will begin to see that while ALL SMs are all more alike than they are different, each individual one is a bit unique. From a cost/joy of ownership standpoint, you will likely be happier with an early SM that has been lovingly and well maintained by her owner(s) vs an SM 2000 that has been neglected by her owner(s) for the last 15 years.
That said, here are a few links discussing the differences between an SM and the SM 2000:
