Datum RMS provides shaft seal services for marine propulsion systems, supporting assembly, servicing, and ongoing support across major manufacturers. Common seal types can be held in stock, with wider availability possible on short lead times.
Marine Engineering Experience
Why Work With Datum RMS
Datum RMS brings extensive marine engineering experience to propulsion work. Our team has practical knowledge across propulsion systems, waterjets, shafting, large onboard equipment, and vessel build and repair environments.
System-Wide Understanding
Experience across shafting, bearings, seals, gears, couplings, and associated marine systems.
Practical Marine Experience
Support shaped by real shipyard, haul-out, installation, and reinstatement requirements.
Reliable Technical Support
A practical approach to removal, replacement, alignment, and reassembly of propulsion components.
Distributor Support
Thordon Shaft Seal Support
Datum RMS is a Thordon distributor, offering the TG100 shaft seal for water-lubricated propeller shafts. This mechanical seal provides built-in “get you home” redundancy and is suited to vessels operating in clean water or dirty, abrasive-laden conditions.
This makes the TG100 a strong option where dependable shaft seal performance is needed in demanding marine service conditions.
Propulsion Project Support
Supporting Reliability Through Haul-Out, Repair and Reinstallation
Why Marine Propulsion Support Matters
Propulsion systems rely on the correct condition, fit, and performance of multiple connected components. Problems with shafting, bearings, seals, running gear, or installation accuracy can affect efficiency, increase wear, and lead to avoidable downtime.
Supporting Haul-Out, Repair and Reinstallation
Datum RMS supports propulsion work across planned haul-outs, repair periods, replacement projects, and installation support. Whether the requirement is a single component or a broader propulsion package, we provide practical service built around marine project realities.
