We Built Our Reputation on Reliability.
Everybody knows the money stops as soon as your generator does. That’s why for the last 100 years, we’ve built some of the best commercial generators on water. Every weld, wire and circuit is a badge of honour. If our craftsmen have touched it, it is good and true. And if our name is on it, it’s going to work. From handcrafted alternators to hand-built controllers, we take pride in building power systems you can depend on.

The First and Only Built-In Paralleling System.
We created the first marine generators with built-in paralleling controllers. Our PGEN connection parallels up to eight KOHLER generators of varying sizes with a single communication wire. When the first generator’s load is light, the second generator automatically drops off. When the load is heavy, the second generator automatically comes online to provide the power needed to carry the load.

Bottom Line. It’s All About Your Bottom Line.
We created the Decision-Maker® 3500 controller to eliminate the need for expensive, oversized switchgear, costly add-ons and complicated installations. Not only that, our new controllers feature auto-transfer functionality. If one generator is in trouble, the second generator senses the problem, starts up and takes on the load— automatically. So your boat will never be dead in the water. And you can keep your business in business.

Pleasure Craft Generators
Always present. Never noticed. KOHLER pleasure craft generators are built and engineered to provide quiet, dependable marine power.

The Highest Level Of Quality.
At Kohler, we believe every generator we make—every weld, wire and circuit—is a testament to our quality. That’s why our latest marine gensets are smaller and quieter with less vibration than ever before. We design and build these machines to exceed certified class society standards. The result: the most advanced, most reliable generators we’ve ever made.

The First And Only.
We created the first marine generators with built-in paralleling controllers. Our PGEN connection parallels up to eight KOHLER generators of varying sizes with a single communication wire. When the first generator’s load is light, the second generator automatically drops off. When the load is heavy, the second generator automatically comes online to provide the power needed to carry the load.

Now Equipped With Peace And Quiet.
Our redesigned sound shield—with separate engine and alternator compartments—and improved air management system significantly reduces sound levels. The quiet is all you hear.

Take Away Vibration. All That’s Left Is Comfort.
On a pleasure craft, comfort is king, and vibration an unwelcome guest. That’s why we go to great lengths to ensure the only thing you feel from your generator is peace of mind. Our proprietary vibration mount cushions the engine as it moves to eliminate vibration. It’s what separates our marine generators from all others.
