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.
Services
The cornerstone of the service program at Jeff's Marine is the maintenance, repair, and rebuilding of Yamaha outboards. We have two full-time mechanics, both of whom regularly attend Yamaha service schools for advanced training in changing outboard technology. Jeff's Marine has a full-time yard crew consisting of experienced boat handlers, fabricators, and fiberglass/paint specialists.
Jeff's Marine is seeking a full-time Bookkeeper. This position reports to and works directly with the company owner and senior management. Applicants are expected to have a working knowledge of basic accounting, business operations, payroll, human resources, bookkeeping, and account reconciliations.
Jeff's Marine was the first Yamaha Outboards dealer in Maine, and we are still the largest in the state today. Although we have sold other brands in the past, Yamahas have stood the test of time-and coastal Maine's demanding conditions-better than the outboards of any other manufacturer. The company has a long history of technological excellence.
14' Utility V-bottom skiffs. We also offer a floorboard package for the 14' V-bottom skiffs. Whether you just want a boat or a boat and motor package, we have everything you need to get you out on the water and keep you going. Stop by to check out our inventory, call us at (207) 354 8777, or email for more information.
Boat trailers have to tackle some of the most punishing conditions out there, from salt water immersion to mud to year-round weather. They also have to provide exacting hull support on the road and easy loading and unloading at the water's edge. Load Rite trailers give you the best of both worlds.

Jeff's Marine sold us a new boat that developed a warranty issue in the first season. They had difficulty with the boat's mfr standing behind their warranty. It took a while, but Jeff's winterized our motor for free, and then had the repair made locally to my satisfaction at Jeff's expense. I was without my boat in the fall, but pleased to now have it was back ready to use in 2022.

I have had nothing but trouble with a Parker 2520 I bought from Jeff's . The boat was repowered with a 357 GM. It was never set up right. The serpentine belt was not aligned correctly---resulted in a broken belt and a tow. The shift of the mercrusier was not adjusted ---no forward or reverse. Resulting in another tow. Motor not aligned---more shop time. U-joints made noise during sea trails---Jeff's said they all make noise. I had to replace the u-joints. Never again!!

DO NOT just let this place do work without giving strict instructions as to what you want. I put my 25 HP ( only 50 hrs) Honda in for idle and new cable adjustment expecting 1-2hrs labor. They did a full engine strip down and rebuild. $621.00 later. No explanation and they broke off the air intake cover left in it in the boat and said nothing. Will not go back. Can't afford to.

I bought a classic 1968 Bertram 20' from Jeff just before he passed away a few years ago and I love the boat. The yard has done a fine job of keeping it serviced, storing it for me and having it ready when I arrive for the summer. Yard specializes in Yamaha outboards -- good stuff!!

WARNING! SHOP SOMEWHERE ELSE.
-- In the fall we traded in a 6hp Yamaha for a 9.9, left a deposit, and was given a receipt by Jeff, the very nice owner.
-- Over the winter Jeff unfortunately passed away.
-- In the spring we came to pick up our 9.9 and the new owners (conveniently) couldn't find our paperwork.
-- They sold us the 9.9 and we left.
-- When we got home we found our copy of Jeff's original receipt. The new owners had charged us $900 more!!!
-- We faxed them Jeff's original receipt.
-- They wouldn't honor it.
-- They wouldn't split the difference.
-- They hung up on us!
