First fuel the Generator with a fuel can. The Gate Control still fails until you repair the machinery: fit a Thermal Coil (electrics), a Gear or Axle (the gear slot), two Buckets on the water wheel, and repair the Water Pump. Then set the four water-flow controls so both water wheels turn, and the gate opens. In the demo, sailing through ends the demo.
Step by step
Fuel the Generator. Bring a fuel can and refuel it.
Try the Gate Control. It fails — that tells you what’s broken.
Repair the electrics with a Thermal Coil.
Fill the gear slot with a Gear or an Axle. Small gears you picked up earlier count (players).
Fix the water wheel with two Buckets.
Repair the existing Water Pump.
Set the four water-flow controls so both water wheels turn.
Use the Gate Control again and sail through.
⚠️ Demo steps from one walkthrough, confirmed in part by players on Steam. The developers reworked the Throat gates area for the September playtest, so the Early Access version may differ — we’ll recheck after Nov 9.
Can’t find a part?
Search the area and floating debris; the Grappling Hook Gun pulls in drifting cargo.
Check your inventory for gears from earlier salvage.
Still stuck: it’s the demo’s most common question on Steam — see the thread in the sources.
FAQ
Why won't The Throat gate open?
Usually a part is missing: the generator needs fuel, and the machinery needs a Thermal Coil, a Gear or Axle, two Buckets and a repaired Water Pump. Then both water wheels must be turning.
Where do I find the gear?
Players say any gear works, including the small gears you may already have collected — check your inventory and get close to the pump/gear slot to repair it.
Is the water puzzle bugged?
Several players asked on Steam. Most 'bugs' were a missing part or a wheel not turning. If everything is fitted and it still won't move, reload a save and report it with the in-game bug button.
What's past The Throat?
In the demo, nothing — sailing through ends the demo. In Early Access the region continues.
