You currently cannot unlock a true underwater mount in Crimson Desert. What players usually mean is Marni’s Mechahorse – a mechanical horse located at a fixed spot south of the south gate of Delesyia, which can currently also move underwater.
If you are specifically looking for a mechanical underwater horse, this is the correct solution. You can find the Mechahorse south of the south gate of the City of Delesyia in the Eastern Hills. The key point: You cannot simply take it – you have to steal it, and for that you absolutely need a mask.
Important: Marni’s Mechahorse is currently not a permanent mount. You cannot store it in a stable. It is a special mount with a fixed location, not a traditional unlock.
Quick summary: Get an underwater mount fast
Travel to the City of Delesyia in the Eastern Hills, leave the city through the south gate, and look directly outside for Marni’s Mechahorse. Make sure to equip a mask beforehand, as mounting it is considered theft. After that, you can use the mechanical horse immediately. You cannot currently store it permanently in a stable.
Location: Where to find Marni’s Mechahorse
The location of Marni’s Mechahorse is clear: directly south of the south gate of the City of Delesyia in the Eastern Hills. You don’t need to enter a cave, solve a puzzle, or defeat a boss. The horse is openly placed in the world.
At the location, you will see several NPCs guarding the area. You can ignore them. What matters is your position: stay directly outside the south gate. If you move further away from the city, you are already in the wrong spot.
The Mechahorse is not immediately recognizable as a usable mount. Only when you are properly prepared can you interact with it and take control of it.

Requirement: Mask for stealing
The most important point is often overlooked: Without a mask, you cannot steal the Mechahorse. The game treats mounting it as theft. Without the proper equipment, the interaction is blocked.
Once you are at the location, check your equipment first. Only then should you interact with the horse. After stealing it, you will be detected. If you leave the area quickly enough, you can usually avoid further consequences.
In practice, this means: Equip mask, interact, ride away immediately. That’s all you need.
Why the Mechahorse is considered an underwater mount
Marni’s Mechahorse differs from normal mounts in two key ways: It does not consume stamina while riding and can currently move underwater. This combination is exactly why it is often referred to as an underwater mount.
Important classification: The underwater usage is currently considered by several guides to be a possible glitch or unpatched behavior, not a confirmed core game mechanic. It is therefore very possible that this function will be removed in future updates.
In practice, this means: You can use the effect right now, but you should not rely on it being permanent.
Can you keep Marni’s Mechahorse?
No. As of now, you cannot keep the Mechahorse permanently. It cannot be registered in a stable and is not available anytime like normal mounts.
Other special mounts have been permanently added to the game later in the past. So it’s possible this could change. For now, however, you should clearly treat the Mechahorse as a temporary mount.
Is the mechanical horse worth it?
Marni’s Mechahorse is mainly worth it as a special mount for certain situations. The biggest advantage is that it consumes no stamina and can currently move underwater. This gives you a level of mobility that normal mounts cannot provide.
However, it is not a long-term solution for normal progression. You cannot keep it, and it does not replace a standard mount you can use anytime. That’s why it’s better seen as a temporary bonus rather than a main mount.
The Mechahorse is most useful if you want to experiment with new possibilities or push current game mechanics. For long-term progression, you should still rely on regular mounts.
Common mistakes with the Mechahorse
The most common mistake is expecting it to be a permanent unlockable underwater mount. In reality, you don’t get a permanent mount, but a temporary special object.
Another frequent mistake is not equipping a mask. Without it, the interaction won’t work – even if you are at the correct location.
Additionally, many players fail due to poor orientation. If you don’t use the south gate of Delesyia as your reference point, it’s easy to miss the actual location.
