OUR TEAM
history
Captain Philip Allen, a trained Diesel Mechanic, 25-year Merchant Marine, and licensed over-the-road Heavy Equipment Inspector, established Corliss Diesel in (2002). He named the company in honor of his direct ancestor, American mechanical engineer George Henry Corliss, the inventor of rotary valves and variable valve timing for a steam engine named after him. Corliss engines delivered 30 percent greater fuel efficiency and surpassed the thermal efficiency of any stationary steam engine for the next half-century.
Corliss Diesel provides complete maintenance and repair of marine diesel propulsion systems and related components. We also perform engine and mechanical surveys and provide pre-purchase advice. Based at the Newport Shipyard, our skills, experience and resources equip us to address almost any power issue.
OUR EXPERTISE
What Our Clients Say
-
"Being in the service business, I know how difficult it is to provide the best service to every client. Corliss did an amazing job on my boat. They did everything they said they were going to do, and then some. I dare you to find Customer Service like that, it truly is a rare commodity."
Robert Kroll

"Simply the best. They helped me fix a Yanmar diesel without hesitation. I called and got service without delay when other companies only had excuses. If you want marine diesel service with professionalism and great customer service, look no further. They are the only marine diesel mechanics that I would ever call in the Newport, RI area. Corliss diesel gets the job done right the first time."

"Very very premium service!! I have three times received incredibly accurate, remote diagnostic analysis of my Volvo Penta engine’s problems. Phil then followed up with sourcing the needed parts faster than anyone else could do, arranged for them to be shipped ASAP, internationally, to the boat in order to keep us moving along on our cruise. Cannot recommend Corliss Diesel highly enough. Call them - especially when in remote anchorages and needing smart help!"
