This means all elements of the generator set are engineered to operate with complete system harmony for optimal performance and the greatest level of efficiency. The best part is knowing your generator is backed by the full power of Cummins. Our line of Cummins Onan gensets and emergency power products will make sure you can boat safely and confidently.
