Power Your Submarine Engine

Choose a Power Source

Your submarine needs continuous power to operate its propulsion system. Common options include furnace engines (powered by fuel like coal), or other Create-compatible generators. Plan your power setup before building the engine.

Install the Motor

Place a Create motor inside your submarine hull, positioned to drive your propeller or paddle wheel. Connect it to your power source using shafts and gearboxes. The motor must have a clear path to rotate without obstruction.

Manage Fuel Supply

If using a furnace engine, keep fuel (coal, charcoal, or other burnable materials) stored in accessible chests inside your submarine. Refuel regularly during long dives. Consider building a larger submarine with dedicated fuel storage for extended expeditions.

Optimize Rotation Speed

Use gearboxes to adjust how fast your propeller spins. Higher speeds consume more fuel but move you faster. Lower speeds are more fuel-efficient for long-distance travel. Experiment to find the balance for your submarine's design.

Monitor Power Status

Watch your engine's rotation indicator. If it stops, check your fuel supply and power connections. A submarine without power is a submarine that sinks—keep backups of fuel and repair materials on board.
