Cummins Marine Mechanic in south western CT?

Looking for a Cummins Certified marine mechanic down my way.

You and me both. They are always 6 to 8 weeks out when you find one.

The only place i'm aware of is Port Niantic Marina. I haven't used them yet but hear they are great. In speaking with Cummins a few weeks back they said Brewers in Westbrook is also certified. Although my experience with them is not positive. Granted it was only related to a lifetime of Merc's that stayed in their marina, as we have a family cottage in Westbrook and multiple boats that lived there over the years. Perhaps their Cummins guy is good. Reasonably priced is always a challenge at any Brewers/Safe Harbor yard...

AND, depending on how far SW in CT, i wouldn't be surprised if Cummins Bronx came up your way. Maybe even Mako Marine out of Freeport NY. After lots of research i had Mako do my engine surveys a couple months back, and they travelled to Stony Point NY. They were willing to do service on the boat too. So perhaps they will head to SW CT. Their tech was very competent. Good luck.
