I can’t say enough good things about Diamond Marine in Ipswich. They installed a new Yamaha engine on my older custom wood boat, and the work was absolutely flawless. The installation was done with precision and care, and they had everything completed quicker than I expected. The team is professional but also down-to-earth, making the whole process smooth and stress-free. Their customer service is top-notch, and it’s clear they take real pride in their work. Being a repeat customer is something I'm looking forward to. I highly recommend Diamond Marine to anyone looking for expert marine service and support. Monty H.

I have always been extremely satisfied with the work and service Jeff Greenwood and his team have provided to my boats. Diamond Marine is an honest and fair outfit, service orientated, friendly and highly knowledgeable. I have used Diamond Marine exclusively for all my boating needs. They have provided countless necessary repairs for me which I cant even count on two hands. Whether it be wiring, power head service, battery configurations, lower unit work, seals and lubrication, tune ups or winterization/wrap, they are always up to the task with constant communication if unexpected issues arise. When I say this group provides 5 star service, and I don't say that often, I mean it! Thank you for everything Diamond Marine, and for those of you who have not heard about this company, please reach out for an incredible experience. Thanks so much :)Services: General repairs & maintenance

Jeff Greenwood is a highly knowledgeable, highly skilled, and highly ethical boating professional with an in-depth understanding of the boat business who always puts the customer first and prizes quality and integrity over profit. I had a major warranty issue that took over two years to correct and he was with me every step of the way, ensuring that the manufacturer (Rossiter) followed through, giving countless hours of his time advocating for my requirements and finding the right solution. You will meet few people like him in the boat business and in life.Service: General installation

Great marine mechanic! I had a quirky problem with my 25hp Evinrude Etec. Took it to another authorized Evinrude shop where they couldn't find the problem, did shoddy work then brushed me off. Jeff at Diamond Marine really dug into the problem to figure it out. For a small job Jeff went above and beyond to find the problem and fix it then submitted it to Evinrude for the warranty claim. All this and I didn't even buy the motor from him originally. This is a business with very high integrity. A breath of fresh air after seeing what the competition does.

I purchased my new Bluewater 2550 from Diamond Marine. I got great deal and I was treated like a VIP through the entire transaction. Jeff and his team were very professional and went far and beyond any other boat dealer!

Diamond Marine is by far the best boat dealer I have experienced in 35 years of boating. I bought two brand new etech 150 engines for my boat and not only did they do a professional perfect install, it was done when promised and for exactly what they quoted. Even more important than that when I had an issue this summer (hit a rock wrecked the lower unit) again Jeff and his crew stepped up handled my insurance company and got me back in the water quicker than I ever expected.
