Object Report: Engine Block Found Near Ellsmere Wreck Site

Old Engine by Shot Line Diving on Sketchfab

Location:

• Site: Near Club Island, St. Lawrence River
• Coordinates: Approximate area near the Ellsmere Steamer Wreck
• Depth: Not specified; likely within diveable recreational depths.

Object Description:

• Type: Large engine block
• Material: Presumed cast iron or steel typical of late 19th to early 20th-century marine engines.
• Condition: Likely corroded due to prolonged submersion in the river environment. Presence of marine growth or sediment could obscure features such as cylinder details or manufacturer markings.
• Size: Described as “very large,” suggesting it may belong to a Steamer or early diesel vessel.

Historical Context:

The Ellsmere was a steam-powered vessel, and the proximity of this engine block to its known wreck site raises questions about its origin. It could belong to:

• Ellsmere: Detached during the wrecking process or subsequent salvage attempts.
• Another Vessel: The St. Lawrence River has seen heavy maritime activity; this could be unrelated and part of a separate shipwreck or mechanical debris.
• Salvage or Dumping: It might represent Abandoned machinery discarded in the area.

Next Steps:

1. Photographic Documentation: Capture detailed images of the engine block, focusing on identifiable features such as:

• Serial numbers or manufacturer plaques
• Cylinder configuration and design
• Any distinct fasteners or assembly details

2. Material Testing: If accessible, determine the metal composition to estimate age or origin.

3. Comparison with Known Data: Cross-reference with shipwreck inventories, particularly for the Ellsmere and nearby wrecks.

• Check David Swayze’s shipwreck database or maritime records.

4. Local Dive Records: Consult dive clubs or historical associations familiar with the Club Island area for additional context.

Advisories:

• Hazards: Possible entanglement risks from river currents or surrounding debris.
• NOTMARs: Report the location to local maritime authorities or underwater archaeology groups for official documentation and study.

Conclusion:

The discovery of a large engine block near Club Island adds an intriguing element to the maritime history of the St. Lawrence River. Further exploration and study may provide insights into its origin, potentially linking it to the Ellsmere or other vessels from the region’s rich shipping past.
