Abstract
A marine outboard motor has a rotary bearing on the vertical drive shaft intermediate its ends. This bearing is mounted in a housing that joins the power head to the lower unit. The bearing prevents failure that may occur when the shaft has an unbalance that causes bowing and whipping of the shaft at certain speeds. The bearing is supplied with water from a water pump in the lower unit.
