A surfboard-based powered water craft is propelled by gas or electric power plant. A water jet pump supplies water under pressure, which is exhausted through a steering nozzle. A steering shaft, carried by the surfboard-based body, pivots in response to movement of a steering arm. The steering arm pivots about a vertical axis and a horizontal axis. The weight of the power plant is carried forward the center, whereby a rider on top of the surfboard based body tends to balance the weight of the power plant.

Provided is a system including a fin box that allows surboard fins to be installed, removed or adjusted to the front or rear of the board within the box and a means for installing the box on the surfboard.

By using the fin box installation system, manufacturers can effectively locate, align and install the fin box on the surfboard. More importantly, the manufacturers are able to lean and rotate the fins precisely at any desired angles and achieve precise and critical symmetrical mounting of the fins with relation to the centerline of the surfboard.

Wireless transmitters are integrated with manual marine-propulsion implements associated with small watercraft (paddles, oars, poles, and the like). The transmitters are controlled by hand-operated actuators. The actuators are designed to be manipulated without looking and positioned within convenient reach of an operator's normal hand position on the implement. A corresponding wireless receiver on a target device enables the transmitter signal to control the device. Thus, an operator of a small watercraft can control a useful target device without first shipping or otherwise securing the manual implement, and may simultaneously continue to manually propel or steer the watercraft with the implement. Application examples include a propulsion-assist motor on a stand-up paddled (SUP) surfboard.
