With out question Tony, Judy & crew are a 5 star operation ! From start to finish. They diagnosed the problem I called about and caught a more serious problem that would have left us stranded. Fitting us in even though we werent local and getting us on the schedule and completed on time and on budget. True professionals that I highly recommend.

THE BEST !! Cant say enough positive things about Tony and Judy at Marine Diesel. Im a new boat owner who unexpectedly needed service while passing through Charleston on our first voyage. Tony went out of his way to get to us quickly (then NEXT day!!) and solve the problem. Helped us diagnose and address multiple issues. No pressure. Fair pricing. Judy (Mrs. Tony I think?) is the office manager, and was super helpful as well. They return calls. They do what they say, on time. Very professional. I absolutely recommend. Thanks Tony and Judy!

Fast and did a great job fixing our raw water pump while traveling through the area. Love this family run team. Would highly recommend.

Tony and Judy are awesome people to work with..even though our new boat was in Charleston and we are in florida, i had complete confidence the job would be done correctly...just talk to them for 2 minutes and you will understand what I mean...professional, trustworthy, and honest...what more can you ask for? Highly recommend them to anyone!

As a recent new boat owner to the Charleston SC area, I could not have asked for better service than what Ive been privileged to experience with MDI. Tony, Judy, and Trevor have been the BEST! If youre wanting experienced, highly qualified, and integrity focused service -- I highly recommend MDI!

Marine Diesels service was impeccable. They worked around the clock for us. They reporting and problem solving solutions, while saving all expenses possible, was greatly appreciated!!

I have had the pleasure of having Tony Godwin with Marine Diesel Inc (MDI) on our boat twice now, both times on short notice and they have always done a fabulous job for us. They are very knowledgeable and easy to work with. Thanks Tony.Capt Ronnie Fields63 Ricky Scarbough “Big OH”56 Island Boat Works “Trophy Box”

We ran into a fuel sensor issue while passing through- Judy and Tony squeezed us in and got us rolling. 👍

MDI just successfully completed an 80-85% new component re-build of the Caterpillar engines on my Hatteras 64 motor yacht. Tony and his family team did a super job on all aspects of this major project. We found MDI to be professional, highly competent, honest, and a real pleasure to work with. We would highly recommend MDI to anyone needing his marine services!!

Excellent service, originally hired for an engine survey on the purchase of a used 2006 Sea Ray Motor Yacht, very thorough went beyond the normal survey perameters, would not hesitate to recommend to any one.

Very professional
