V-Drives/Direct Drives

V-Drive/Direct Drive Service & Repair

What is a V-Drive/Direct Drive Boat?

A V-drive boat that is powered by a rear-mounted engine, propeller, two drive shafts, and a gearbox. In a “V-drive” boat, the engine faces aft with a transmission connected to the rear of the engine. The first drive shaft connects the rear of the transmission to a gearbox mounted in the center of the boat. The second drive shaft extends from the gearbox to the rear and out the bottom of the boat to where a propeller is mounted.   Left: An early style V-drive boat.
