How an Outboard Lower Unit Works | How an Outboard Gearbox Works |

How does a boat transmission work? In this video from Boats.net, Garrett will use our lower unit cutaway to show you precisely how the gearbox works in your outboard. He’ll take you on a tour of the lower unit from the drive shaft, through the water pump, and into the gearbox where you’ll see how power is transferred from your motor to the water.
