Dumb ideas, over engineering and boats go together don't cha know.
Volvo had the cone clutch shift in their drives from day one. A good smooth shift. But the electric worm screw lift motor sucked. Later followed Merc.
Merc has, until the new electric shift drives come out next year or two, the Alpha which requires ignition intteruption to shift and has poor quality cables.
The bravo was better like the Volvo but when they coupled it to the diesel, the cone clutch came apart.When the patent on the alpha drive expired, OMC tried to shelf the first electric shift and then the push/pull cable shift drives for a drive like the Alpha called the cobra.
Which came apart due to shift cable problems and shift intterupt failures and then faded into the unknown.Then came the duo prop phase.
Now it seems they mated the saildrive, turned it around and added a second prop.
Ya have to give all those high paid engineers something to do. Reinventing the wheel is the first week of engineering school.
