Er... 3 point SIX?

The first time I ever heard it was when the EZ30 was announced. While
you could call a boxer-4 an H, Hs don't have three arms on each side,
or one, 4 or 6 either...

Yes, boxers are nothing new, I am fully cognizant of that.

I think some boat diesels from way back (preWW2) had this sort of
opposed-with-chamber-between-piston-crowns layout... could only work
as a 2-stroke. I don't know about modern outboards; I would expect
they'd be a square-4 design, sort of a watercooled 2-stroke version
of the old Ariel bike engine. That is, with cranks parallel, set
side-by-side, geared (no excuse for chains!) together, with pistons
in a square layout when viewed down the barrels. You could do a six
this way too (a rectangular-6, sounds pretty awkward), but cooling
might become a problem; I think outboard sixes are Vs.
