This reports on the new Seven Marine 557hp Outboard. http://www.boats.com/blog/2011/02/se...ami-boat-show/
This picture shows their "Propriety transfer case" which many are assuming to be a belt or chain. If its a belt, that is one heck of a belt. http://www.boats.com/blog/wp-content...rick-davis.jpg
Does anyone have any details??
Eric Davis was asked how the engine’s power made the 90-degree change in direction to mate to a drive shaft, and he just shrugged and smiled. “I’ll have to explain that to you later,” he said. Apparently the Seven team is not ready to reveal all of its secrets.
We do know that shifting is accomplished above the gearcase. The gearcase has a four-inch-diameter tube – a standard size – but has twin pinion gears to transfer power from the vertical drive shaft to the horizontal prop shaft, while keeping the size of the case small and hydrodynamic. An integral power steering system was developed with the input of Latham Marine, and the motor will be rigged with custom Hering propellers.
