Dual-discharge fuel pump positioned between cylinder rows supplies balanced injection pressure to both banks.

Integrating conducting tracks into the stator winding head board reduces axial length and ohmic losses in electric rotating machines.

Feedback control adjusts bucket angle and engine speed to maintain ship position against wind and tidal current disturbances.

Automated motor control corrects ship propulsion tilt angle based on real-time hull angle sensor readings, resolving manual adjustment inaccuracy.

External threads on the propeller shaft engage a nut to clamp driven gears, reducing gear case axial dimensions without separate preloading mechanisms.

A pod drive reduction gearing system uses a planetary mechanism to transmit torque from a high-speed electric motor to the propeller shaft.

Segmented stator housing enables easy installation and removal, preventing water ingress while maintaining streamlined hydrodynamic efficiency.

A mounting body with a stowage cavity receives an actuation arm in a first position, resolving space constraints during storage.

An outboard motor mount with an adjustable distance between the tilt shaft and trim cylinder shaft.

Nested inner and outer tubes with annular seals enable quick underwater pod removal without compromising hull waterproofing.

Automated deflector trim adjustment stabilizes boat body during reverse-to-forward shifts without manual intervention.

A fixed support position for the flexible connector eliminates the need for a large motor well, preserving hull strength and reducing exterior exposure.
