Praise From Our Customers

Free Martin

Eric and Amanda live and breathe boats. They want to talk to you if you are looking at buying a boat, having a boat winterized, wrapped and/or stored. Eric is retired from the USCG (thank you for your service Eric) and knows boats and motors inside and out. Amanda is a savvy business woman that believes in running the business the right way. This company is a locally owned family business that is here to help boat owners. You will not find better people to handle all your boating needs. They will treat you like family when you step inside their Dedham shop. I'd talk to them about consignment too. Route 1a gets a lot of traffic and their lot is a great place to sell your boat.

Eric went out of his way to help us in a pinch. He went above and beyond. I would recommend M3 Marine to anyone for their service or sales.

James Grant

Excellent customer service! Highly recommend for your storage and service needs. Picked up trailer and was not prepared like I should have been and they were more than helpful to make sure I was taken care of.

Michael Brooks

Randy Porter

I have used about a dozen different Marina's in the area. Started using them last year. Unbelievable job! From motor/boat knowledge, customer service, to boat wrapping, way above standard. They will go out of their way to help you.

Eric and Amanda saved the day! We only had 1 day to fish this 4th of July, but I couldn’t get the boat motor to turn over. I called M3 to drop off the boat for service, knowing it would be a week or so before they could fit me in - figured I’d have it ready by our next trip to the cabin in August. When I arrived with the boat Amanda asked Eric to take a quick look to see if anything stood out (maybe a flipped kill switch or something). Eric noticed an issue immediately, stopped what he was doing, and had it fixed in 15 minutes. I know they were swamped with work, but they were kind enough to go the extra mile for us. THANK YOU!!

4th generation on the lake (correct me if I’m wrong). Doing business with this company since its inception, OUTSTANDING! Put Camp Capella’s boats in . Wonderful family, so happy to have them in our community.

Timothy Davis

I am so happy that I found M3. Before I was left with the task of having to trailer, launch and service my own boat. Not to mention the hassle of winterizing and storing it all myself. Now they do all of those things for me leaving me with more time to spend with family and friends out on the water ! Thank you M3 for making boat ownership so much more enjoyable.
