Insert the motor into the sealed compartment, ensuring the drive shaft aligns precisely with the offset cam mechanism. Assemble the tail fin linkage by connecting the plastic rods to the cam follower, then attach the flexible tail fin to the linkage assembly. Install the polycarbonate hull halves using the provided fasteners, ensuring watertight sealing around the motor compartment access point.\u003c\/p\u003e\n\n\u003cp\u003eOnce assembly is complete, insert two AA batteries into the battery compartment located at the rear of the hull. Switch on the motor using the simple on-off switch, then place the blowfish in water with the tail fin fully submerged. The mechanical system will immediately begin oscillating the tail fin in a swimming motion. Adjust placement in water to achieve optimal buoyancy where the fish maintains neutral buoyancy approximately mid-depth. For extended operation, prepare additional battery sets as runtime is approximately 30-45 minutes per pair of AA batteries depending on water conditions and motor wear.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eWhat is the swimming speed and range of the Mechanical Blowfish?\u003c\/summary\u003e\n\u003cp\u003eThe Mechanical Blowfish achieves swimming speeds of approximately 0.3-0.5 meters per second in still water conditions. The effective operating range is limited by battery life rather than motor performance, providing approximately 30-45 minutes of continuous swimming operation per AA battery set. In larger bodies of water, the robot can traverse 30-50 meters before battery depletion. Speed varies based on water temperature, density, and tail fin wear over time.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eIs the Mechanical Blowfish truly waterproof for saltwater environments?\u003c\/summary\u003e\n\u003cp\u003eThe motor compartment features sealed waterproof construction suitable for saltwater operation, though extended saltwater use may cause corrosion of internal metal components over time.
