Jeff’s Marine is a year-round, full-service Yamaha and Duranautic dealership serving the Maine coast from Belfast to Boothbay. Our customers include hard-working fishermen, local boating enthusiasts, and vacationing families. Owned and operated continuously since 1982 by longtime Thomaston resident Jeff Armstrong, Jeff’s Marine has always made delivering excellent service its highest priority. Most of our customers have been with us for many years, if not decades, and we’re proud to call them friends.
During the COVID-19 outbreak, we remain open as an essential business to serve commercial fisherman and boaters. Our mechanic bays and storage areas are currently closed to customers and vendors. When visiting the marina we ask that you wear a mask to protect yourself and other customers, or maintain six feet of social distance. Please call in advance if you need to order a part, drop off a small engine for service, or pick up a boat or motor. For all sales inquires, please call or email.
We appreciate your continued support and wish our community and customers health and happiness.
