If I were running offshore, I would have 2x300, but I do get your point.Where a motor like this makes the most sense (beyond a d*ck measuring contest) is where it replaces two 300 HP motors. Much more efficient and less maintenance to have one lower unit in the water and one power plant to service. Plus, as you said, it brings other efficiencies to the table. I can't recall the numbers, but a dealer at the show claimed significant, real world fuel savings going from twin 300s or even twin 250s to the 600. Also, the technology debuting here will work its way down to the lower HP models over the next couple of years.
