Last year, Volvo shuttered Seven Marine, which built outrageous outboards based on supercharged GM LS V-8s. If Mercury's past practice is anything to go by, we can expect a supercharged version of this motor from Mercury Racing in the near future.
Sound outrageous? Consider that, Mercury says, a pair of these offer 20 percent better fuel economy than triple (Yamaha) V-8s.Mercury has released a V-12 outboard marine motor that makes 600 horsepower.
