CUT EMISSIONS. SAVE FUEL.

The Cat® product line doesn’t simply meet the 

latest marine engine emissions regulations — our Tier 4 Final engines are performing in engine rooms, on the water, day in and day out. By using Selective Catalytic Reduction (SCR) to reduce emissions downstream of the engine, you get the same iron you’ve always counted on to perform in tough marine environments. The SCR system doesn’t affect engine efficiency or durability like other emissions-reduction solutions.
