Providing the Chesapeake Bay region’s best boat and motor services begins and ends with one thing – our people and their dedication to always do what’s right. Tri‑State Marine prides itself on providing the absolute best in marine services, which has been achieved through the continuity of our expert management and certified factory-trained service technicians — many have whom have been with Tri‑State Marine for more than 30 years!
But, don’t take our word for it, simply ask our customers or look to the many customer satisfaction awards that we’ve earned. Most recently we achieved Grady-White’s highest honor, Admiral’s Circle for Excellence in Sales and Service, our 23rd consecutive year, and we have achieved a 9.76 rating (out of 10) on Grady‑White’s 3-year average Customer Satisfaction Index. Also, you can rest comfortably knowing that we’ve been an exclusive partner to Yamaha Motors for 37 years. We are 5-Star Gold Certified and a Pro Elite Dealer, placing us in the top 3% of all dealers nationally and the ONLY dealer in Annapolis/ Chesapeake Bay area that has achieved this prestigious dealer rating, with only the best factory trained technicians, including their highest certified honor, master service technician.
While we’re honored to receive such high praise, we’re most proud of the quality of our customer service. When combined with the quality of our work, it provides you with the experience that you would expect while giving you the confidence to comfortably and safely enjoy your days on the water. And when the season ends for some of you, we take incredible care of your investment during the offseason — whether it’s decommissioning and storage or if you have off-season plans for work that you’d like us to perform on your behalf.
No matter your needs, Tri‑State Marine provides you with the best service at competitive rates. To schedule a service, please call our Service Department directly at (410) 867-1960 or complete our Online Service Request form.
