According to at least one embodiment, an electric actuator for a marine steering system is disclosed. The electric actuator includes a housing, an output shaft, a screw assembly coupled to the output shaft, a rotor coupled to the screw assembly, and a motor configured to rotate the rotor. Rotation of the rotor causes the output shaft to translate axially relative to the housing.

The present invention provides a tail rudder control system for a kayak which includes a tail rudder assembly, having a tail rudder, a swing mechanism for driving the tail rudder to rotate in the horizontal direction, a traction mechanism for driving the tail rudder to flip longitudinally for storage, and a guide wheel box for driving the swing mechanism and reset the tail rudder. Two pedal assemblies are in transmission connection with the swing mechanism through a steering traction line for driving the swing mechanism to act. A transmission assembly includes a first transmission wheel wound with a transmission traction line, a second transmission wheel wound with a reverse traction line. The second transmission wheel is driven by the first transmission wheel, and the reverse traction line is in transmission connection with the traction mechanism for driving the traction mechanism to act.

A tiller system for steering a marine propulsion device. The tiller system includes a tiller arm rotatably coupled to the marine propulsion device. The tiller arm is rotatable from a down position to an up position through a plurality of lock positions therebetween. A toothed member is coupled to one of the tiller arm and the marine propulsion device. The toothed member defines a plurality of teeth corresponding to the plurality of lock positions for the tiller arm. A pawl is coupled to another of the tiller arm and the marine propulsion device, where the pawl engages with the plurality of teeth to prevent the tiller arm from rotating downwardly through the plurality of lock positions.
