Corliss works exclusively with Boston Fuel Injection for testing and rebuilding of all
relevant components. BFI has been New England’s leading specialist since 1953.


Whether you need more power, more modern propulsion or both, we can perform complete powertrain upgrades or replacement. Working directly with manufacturers including Yanmar, Perkins, Cummins and CAT, Corliss can offer you a full spectrum of options.



Corliss Diesel provides detailed, pre-purchase marine mechanical surveys. These verify
the condition of engines, drivetrains and generators, and alert you to both immediate and
potential issues.
