ABSTRACT:
A marine propulsion steering apparatus includes a steering nozzle having a central opening therethrough which surrounds a marine propulsion drive shaft and propeller extending from a hull or propulsion module. The nozzle is pivotally mounted for angular movement in a predetermined range of movement on the support structure for the drive shaft for directing flow of water from the propeller in response to pivotal motion controlled by a steering mechanism.
