Rehlko

Rehlko Marine, reliable marine power with resilience – always present, never noticed.

Focused on energy resilience and innovation, Rehlko (formerly Kohler Marine) provides marine-specific generator solutions that help power your vessel and use requirements. Compact, efficient and designed for real-world performance, Rehlko products are all about keeping your vessel powered, customized to your exact specifications.

The First And Only

We created the first marine generators with built-in paralleling controllers. Our PGEN connection parallels up to eight Rehlko / 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.

A Reputation Built 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 honor. 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.

Reliable Marine Power

Every Rehlko marine generator is extensively quality-tested—before model release and before leaving the factory. The result is proven reliability.
