Marine Engines

In 1951, Ken Gallup, founder of Point Judith Engine and Supply, became a Detroit Diesel dealer. When Ken’s son Barry took over the reins in 1965 the company’s name changed to Rhode Island Engine Co., Inc. (RIE). Over the years as Barry ran the business and the next generation took over, Barry’s sons Jay and David, the company grew and expanded the number of dealers to the point where RIE is now a factory-authorized full sales and service dealership for every major marine diesel engine brand worldwide.

At RIE we have a modern 8,000 square foot facility in Narragansett, R.I. equipped with the latest tools and technology to install and repair today’s sophisticated marine diesel engines.

Our highly trained technicians, with decades of combined experience, can repair or rebuild just about any marine diesel engine made and we are justifiably well known up and down the New England Coast for new installations and re-powers.

We can design and install new electrical, exhaust, refrigeration, heating and complete engine and power train systems in boats ranging from large commercial vessels, to Tug Boats, to Ferry Boats.


MAN engines offer a wide range of high-speed four-stroke diesel engines for commercial use. A characteristic feature of MAN marine engines is their powerful acceleration coupled with shallow fuel consumption. Their advantages are to be found above all in their outstanding power efficiency, compactness, and reliability.

The engines are delivered ready for installation and are designed for optimum performance in the various conditions of deployment and operation. All engines comply with the internationally applicable exhaust-gas regulations.
