A stern drive system includes a jet nozzle that is pivoted with respect to a mounting bracket and is steered by two hydraulic cylinders. An anti-rotation brace includes a rod pivotably mounted to the bracket and a sleeve pivotably mounted to the jet nozzle. The rod, the sleeve and the pivot mounts are constructed such that the antirotation brace prevents the jet nozzle from rotating about the longitudinal axis of the stern drive system, thereby allowing a modular, compact stern drive which provides advantages in terms of reduced manufacturing cost, reduced maintenance cost, and increased ease of installation.

In a stern drive system comprising: first and second propulsion elements; a bracket configured to support the first propulsion element outside a hull of a water vessel; a pivot joint interconnecting the first and second propulsion elements; and at least one actuator coupled to the second propulsion element to steer the second propulsion element; the improvement comprising: an anti-rotation brace comprising a first portion and a second portion; said first portion secured in place relative to said first propulsion element to resist rotation about a first axis defined by the first propulsion element; said second portion secured to said second propulsion element to resist rotation of said second propulsion element about said first axis; said first and second portions slidably interconnected to telescope together; said first and second portions effective to brace the second propulsion element against rotation relative to the first propulsion element about said first axis, while accommodating steering of the second propulsion element by the actuator.
