Frequently Asked Questions About Our Marine Diesel Generators

PDG has a variety of marine generators for sale, and we're here for the long haul when you buy from our website. We put together a list of answers for some frequently asked questions we receive regarding our marine diesel generators.


How Long Does Shipping Take?

Depending on your location within the continental United States, delivery of your marine generator can take up to seven business days after your order is processed. Overnight shipping may be available. Contact us for more detailed shipping information.

What's the Difference Between Keel-Cooled and Heat Exchange Marine Generators?

Keel-cooled marine generators have a closed-circuit cooling system that is mounted externally on the vessel's hull below the water line. Coolant in the system transfers heat by circulating through the keel cooler, similar to a car's radiator.

Heat exchange marine generators pump seawater from beneath the vessel and pass it through a heat exchanger. The heat is transferred to the seawater which is then pumped back out of the vessel.


Where Are Your Marine Diesel Generators Made?


Like all of our industrial and commercial products, our marine generators are manufactured right here in the United States. Produced from our factory space in Valdosta, we deliver the very best quality and service to our marine generator customers.


PDG will do what is necessary to make sure you are happy with your purchase. We will work with you and our network of dealer repair centers to ensure your generator is running as it should. Ample time should be allotted for this by the customer. Generally, this time frame is expected to be under thirty days.


After thirty days, if the generator is still not performing properly, PDG will authorize a return.


All returns for any other reason will be charged a 20% restocking fee plus any damages incurred to the unit by the customer. Return shipping will be the sole responsibility of the customer.
