I just heard from a reliable source today that Mercury will be releasing a 15" version of the new 400R in the Fall. It is estimated to be 66 pounds lighter than the 20" version - which would put it at 612 pounds. Still too heavy for boats 20' and under imo, but it would be badass on an Argo or Twister! Also would work well as twins on 30' - 34' cats.
