Anybody know who manufactures the current Merc 75/90/115 four stroke

Until this year, Mercury used Yamaha powerheads.
But this past weekend I attended a boat show and noticed major
differences in the appearance of new Mercs and Yamahas. I quizzed a
sales guy and he told me Mercury is making their own powerheads now. I
haven't checked further so take that for what it's worth (I'm normally
a little skeptical of car salesmen selling boats). But there's a
definite difference in their appearance.
