Various aspects provide for “parking” an apparatus in a “parking position.” A parking position may be a configuration of an apparatus that minimizes damage resulting from extended exposure during periods of inactivity. An apparatus may comprise a marine apparatus, which may be configured to be disposed in an environment comprising saltwater, salty air, brackish water, freshwater, and the like. An apparatus may comprise a propulsion system (e.g., for a ship) and/or a steering system. Some aspects include a water jet based propulsion system having a scoop and a nozzle operable to redirect the water jet, providing a range of forward/backward and port/starboard thrusts. A control cylinder and/or a linkage may be parked in a configuration that segregates damage incurred during periods of inactivity to portions of an apparatus not needed for normal operation.
