We recently acquired a large inventory of overstock marine components and spare parts. These items were originally designated for installation on a vessel undergoing a refit and repower project. Before the project was completed, it was canceled and all remaining components were placed into storage.

Based on the documentation we acquired with the project, we believe this hydraulic power unit (HPU) is associated with the Nautical Structures EZ6000-KB-200-342 system. However, we also believe the original EZ6000-KB-200-342 unit may have already been installed on the vessel before the project was canceled, or it may have been removed separately. The information we are providing is based on the project documentation that accompanied these components.

We are currently in contact with Nautical Structures to obtain additional information regarding this HPU, including specifications and compatibility. For the most accurate compatibility information, we also recommend contacting Nautical Structures directly.

Please be advised that the identification information on the electric motor has been painted over, and the identification labels on the attached gear pumps are no longer legible. Because of this, we are unable to provide the motor or pump specifications at this time. We are actively working to obtain additional information from Nautical Structures and will update the listing if more details become available.

If you have any questions or would like additional photos or measurements, please don't hesitate to contact us.

Please review all photos carefully, as they are part of the item description. This listing is for the hydraulic power unit (HPU) only. Any additional components or documentation shown in the photos are included only if pictured.
