Welcome to Jeff's Marine, Inc.

 Who We Are

Jeff's Marine is a year-round, full-service boat-and-motor dealership serving the Maine coast from Belfast to Boothbay. Our customers vary from hard-working, island-based lobster fishermen to vacationing families who simply like to enjoy and explore local waters.

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.

What We Sell

Jeff's Marine is the oldest and largest single store dealer of Yamaha outboards in New England. Although we have sold other brands in the past, Yamaha motors have proven to us their superiority in design, performance, and—especially—durability in salt water.

Carolina Skiffs  represent a great value in their baisic work skiffs up to their fully loaded center console fishing machines.  Come by and see us to check our inventory or see what we have on order.  These boats are all extremely simple and can be set up to meet virtually any need, from tending a commercial aquaculture operation to towing the kids on inflatable toys, to serious fishing adventure.

Jeffs Marine is excited about taking on a new line of boats.  Made in North Carolina, C-Hawk Boats Have been around for 35 years.  They cover our customers’ needs very well with center console models of 16’, 18’, 20’, 22’, 23’, 25’, & 26’ as well as cabin models of 22’, 25’, and 29’, all set up for modern outboard propulsion and fully pre-rigged with consoles, steering, t-tops, high quality stainless hardware, running lights, bilge pumps, leaning posts, fish boxes, etc..  C-Hawk also offers bare commercial hulls for our many hardworking commercial customers living and working on the Islands and coastal working waterfronts, which can be paired with tiller steered propulsion to maximize working deck space, or to be set up by owners in the way they wish to use the craft, with side consoles, haulers, davits, etc.
