About Our Diesel Engine Specialists in New England

Casco Bay Diesel & Injection Service is a proud family-owned company spanning three generations founded in 1994 by Bob Chamberlain. Providing the finest powertrain service to be found in the northeast, our diesel engine shop is now owned and operated by Bob’s daughter and son-in-law, Angela and Galen Gullatt.

As an established engine builder and repair service, our shop has developed a reputation as the business to trust with maritime, commercial, industrial, and recreational diesel applications. Our diesel engine specialists in New England work on emergency vehicles, fireboats, commercial fishing vessels, yachts, recreational marine vessels, and industrial construction equipment as well as standby and primary power generation units.

Of course, our primary focus is diesel engine and transmission service. We can perform an overhaul on a vessel, or we can rig the equipment for removal and repair it at our shop. No job has ever been too big for us to handle. If a repower is required, we can handle that as well.

In addition to the products listed on our home page, we have also provided major service on Electromotive diesels, Fairbanks-Morse(r), Alco(r), Murphy(r), Perkins(r), Ford-Lehman(r), Lister-Petter(r), John Deere(r), Scania(r), Navistar(r)(International), and Volvo(r) engines. We service Twin Disc(r), Reintjes(r), Caterpillar(r), and Velvet Drive(r) transmissions, as well as both industrial and marine ZF(R) gearboxes. PTOs and hydraulic pump drives are also serviced at our shop. We have acquired much special tooling to maintain these products and continue to upgrade our equipment as the need arises.

We also have had the opportunity to work with insurance companies and marine surveyors when there has been a problematic, catastrophic failure, helping our customers with the benefit of our expertise that they need in order to get problems resolved for insurance claims. Figuring out the cause of a failure is a lot like detective work, and it takes a particular set of skills.

Most lawyers have no clue what goes on when an engine or transmission had failed, which is understandable since that is not their field. That is why our skilled mechanics have served as expert witnesses in Florida, New York, and Maine. We enjoy the teaching part of the process more than anything. Nothing beats experience. We also have contacts with many experts in specific fields around the country when there is a particular problem that requires more in-depth information.

Remember, nobody knows everything, and we are continually learning. When you stop learning, you stop living.
