I thought the same as you Adam - had to be photoshop.
If its real that thing would be a real pig to turn - ski boat racing makes up a fair chunk of my dim dark past (no boat jokes please!!!!!!
)
Ran twins and triples but you had to get all the motors to turn in unison to get any sort of agility. Fixed mounting of those middle four would mean that they are trying to drive it in straight line all the time. This thing is designed to go bloody fast in straight line not turn.
60knots - no way this thing would go heaps faster if real.
(60knots = 70mph or 112kph) - you can get that out of high performance single 250/300 outboard.
My guess would be closer to 100knots.
The fuel tanks would have to be enormous as well.
