Cummins 6BTA (5.9 L) 280 HP Marine Diesel Engine Package

$18,500.00

Whether you are looking to replace an existing 4BT/6BT marine engine or interested in doing a complete repower we can help. The 6BT (5.9 L) 280 HP Marine engines are perfect for commercial fishing vessels, small trawlers, supply boats, patrol boats, skiffs, tugs, pontoons, and pleasure boats.

Mechanical Cummins 4BT and 6BT engines have been popular for repower projects due to their lighter weight, available power, and significantly lower cost over Yanmar or Volvo Penta engines. Common repower projects include the old Detroit Two-Stroke 4-71s and 6-71s, Perkins 4.154, 4.326 and 6.354, Ford Lehman, Mercruiser, Sterling and Gray Marine.

Our Reman 6BTA (5.9 L) marine engines essentially come as complete engine (extended long blocks) and include wet exhaust manifolds, water cooled turbocharger, marine rated fuel pump, fuel lines, injectors, marine rated pistons, heat exchanger, sea water pump and oil pan. Our Cummins 4BT/6BT Marine engines are designed to be connected to a gearbox with a fixed-pitch propeller; additionally engines can be connected to a ControlledPitch Propeller System (CPP). All marine engines come as a standard “Left Hand” Counter Clockwise Rotation (CCW). Directional rotation can be identified when inspecting the flywheel rotation. Engines are all run tested and ready to ship.

Our marine long block and extended long block assemblies are considered ‘component builds’. A new component build is an engine assembly built back to popular configurations using roughly 90% OEM parts, 10% Aftermarket when available.

New Remanufactured Component Builds do include limited rebuilt and/or remanufactured components when necessary but frequently they are non-critical wear parts such as aftercoolers, exhaust manifolds, fuel pumps, water inlet and outlet connections, gears, gear housings etc… Each build cycle we do is different and follows compliance standards governing re-use guidelines.
