Casco Bay Diesel started as a one man operation in 1994 by Bob Chamberlain and his wife Cathy.
His goal was just to provide more personal attention to his customers in the marine and heavy equipment industry, servicing engines, transmissions, and other related components on just about anything with a diesel engine.
In 2018, Bob wanted to focus more on working in the shop and diagnostic work- which is his passion. He sold the company to his daughter Angela and her husband Galen Gullatt.
That same year, Casco Bay Diesel acquired “Cornell Diesel”, which had been a fuel injection pump shop in Portland for over 50 years, and the company became Casco Bay Diesel and Injection services.
With the new fuel shop and several new engine dealerships, we have two fully authorized service centres in Portland, Maine and Hyannis on Cape Cod, Massachusetts. We also have 9 service trucks and primarily cover the coastlines of New England.
Casco Bay Diesel strives to be as transparent as possible. We answer all your most asked questions to the best of our ability.

Founded on decades of specialized marine expertise, Casco Bay Diesel has grown into a premier New England provider of marine and industrial diesel solutions. Our team consists of factory-trained technicians who specialize in high-end propulsion systems, combining traditional mechanical craftsmanship with modern electronic diagnostic capabilities.
Our technicians are factory-certified by world-leading engine manufacturers, including Yanmar, Cummins, Scania, and MAN. We invest in continuous training and the latest proprietary diagnostic hardware to ensure our team can perform authorized warranty work and complex system overhauls to manufacturer specifications.
Yes, we operate two primary hubs to serve the New England coast: our main facility in Portland, Maine, and our southern branch in Hyannis, Massachusetts. These strategic locations allow us to provide rapid-response mobile service and shop-based repairs to clients from the Mid-Coast of Maine down to Cape Cod.
Unlike general mechanics, Casco Bay Diesel is a specialized diesel entity with dedicated fuel injection testing labs and dealer-level diagnostic software. Our focus is exclusively on diesel performance, allowing us to provide deeper technical insights, accurate engine surveys, and authorized parts that general shops cannot offer.
As a local business with roots in Portland and Hyannis, we support the maritime community by providing reliable service to both commercial fishing fleets and recreational yacht owners. We prioritize minimizing downtime for our clients, recognizing the vital role that dependable diesel power plays in both New England’s economy and maritime safety.
