Always Present, Never Noticed KOHLER® marine generators are smaller. Quieter. With less vibration.* In other words, you won’t notice our generators, and that makes all the difference.Our overall footprint is up to 16” shorter, for more power density in a smaller package.* That makes it easier to install and repower – it fits into smaller applications where other generators can’t. Our redesigned sound shield (with separate engine and alternator compartments) and our improved air- management system significantly reduce sound levels. Our proprietary vibration mount cushions the engine as it moves, to eliminate vibration. It’s what separates our marine generators from the rest of the world’s.
