What this video covers

Dan and Kika install two Oceanvolt ServoProp motors into their 36-ft sailboat, Uma, to replace a single-motor configuration.0:06 The upgrade aims to double regenerative power generation while sailing and improve maneuverability during docking by allowing independent control of two motors.4:58 The crew previously glassed and sealed watertight compartments into the hull to house the motors.6:24 Installation involves feeding control cables through the skeg using a braided sleeve, securing the units with long guide bolts, and sealing the assembly with O-rings to protect the oil-bathed internal components.8:48 Because the hull contour requires the motors to be mounted at an angle, the crew uses guide bolts to manage torque and alignment during the mounting process.10:09 The project also requires additional fiberglass work inside the hull to ensure the motor compartments remain watertight before final priming and electrical integration.19:23 The dual-motor setup provides system redundancy, ensuring that a failure or line entanglement on one propeller does not leave the vessel without propulsion.5:13
