Mercury has showcased a new V-12, 7.6 L outboard producing 600 hp. It has a 2 speed transmission and only the lower gear case/ foot turns. The top end stays stationery. Dual counter rotating props, weighs 1200+ lbs. So if you are looking to repower your big offshore center console, here is your solution. On the test boats, Mercury mounted 4 of them on a 46’Viking and 3 on a slightly smaller Boston Whaler.

What an intriguing idea. Top of motor stays in place and bottom moves to steer the boat.
