From main propulsion engines to auxiliary power units, The Marine Yard maintains a substantial owned inventory of marine engines sourced from active vessels and fleet operations — available for immediate purchase.
At The Marine Yard, marine engines are one of the most consistently available categories in our inventory. As a division of River Salvage Inc., we regularly acquire engines through vessel salvage, fleet retirement, and project take-outs — giving us a broad and frequently updated selection of main propulsion and auxiliary engines across a wide range of makes, models, and power ratings.
Our engine inventory includes diesel main propulsion engines from leading manufacturers including Caterpillar, EMD, Cummins, Detroit Diesel, MTU, and others. We carry engines across a wide range of horsepower ratings — from smaller auxiliary and generator-set engines to large high-output main propulsion units suited for tugboats, towboats, and commercial vessels.
Whether you are looking for a direct replacement engine, a rebuildable unit, or a surplus engine for parts and reconditioning, we maintain inventory across multiple configurations and power ratings. Stock changes frequently as new engines arrive through ongoing salvage and fleet operations — contact us for current availability.
High-output diesel main engines for tugboats, towboats, pushboats, and commercial workboats. Available across a broad range of horsepower ratings from leading marine engine manufacturers.
Auxiliary diesel engines for ship service power, hydraulic systems, pumps, and secondary vessel functions. Sourced from active vessels with documented service backgrounds.
Marine generator sets for vessel electrical power generation. Available in a range of kW ratings for commercial vessels, workboats, barges, and floating facilities requiring reliable onboard power.
Marine reduction gearboxes and transmissions to accompany propulsion engines. Various gear ratios and shaft output configurations available for matched drivetrain replacement.
Run-out, damaged, or non-running engines available for rebuild, reconditioning, or parts harvesting. Useful for operators maintaining existing fleets with hard-to-source engine models.
Engines removed from vessels during upgrades, conversions, or decommissioning. Often in good running condition, available at competitive prices as direct fleet surplus.
Direct replacement of worn or failed main propulsion engines in tugboats, towboats, workboats, and commercial vessels — restoring full operational capability at competitive cost.
Sourcing main and auxiliary engines for newbuild commercial vessels, work barges, and marine construction platforms where surplus engines offer significant cost advantages.
Maintaining spare propulsion and generator engines for fleet operators requiring rapid swap-out capability to minimise vessel downtime during unplanned engine failures.
Acquiring rebuildable or parts engines as the core of engine overhaul and reconditioning programs — cost-effective sourcing for marine engine shops and fleet maintenance operations.
Generator sets and auxiliary engines for powering crane barges, dredges, work platforms, and floating facilities requiring independent onboard electrical and hydraulic power.
Surplus and take-out engines used as parts donors for maintaining older or out-of-production engine models where new OEM components are scarce or cost-prohibitive.
We acquire engines directly through vessel salvage and fleet operations — giving you accurate condition information, broad model selection, and competitive pricing without brokers in the middle.
Our engines come directly from vessels we have salvaged or decommissioned — no broker chain, no unknown history, no inflated margins.
Caterpillar, EMD, Cummins, Detroit Diesel, MTU, and more — our inventory regularly spans multiple manufacturers and a wide range of horsepower ratings.
We carry engines in various conditions — running surplus units, take-outs, and rebuildable cores — giving buyers options across different budget and application requirements.
Matched reduction gearboxes and transmissions are frequently available alongside propulsion engines — simplifying sourcing for complete drivetrain replacements.
New engines enter inventory regularly through ongoing salvage and fleet operations. Contact us directly for current availability — stock changes frequently.
From towboats and barges to cranes, excavators, and marine engines, we offer a wide range of equipment tailored to meet the needs of our clients. Our commitment is to provide reliable products, exceptional service, and long-term value.
