Mercury Marine & MerCruiser Service in Plymouth, MA
Independent Mercury outboard and MerCruiser sterndrive service, maintenance, and repower at Atlantic Boat Repair in Plymouth, MA. Serving the South Shore, Cape Cod Canal, and Buzzards Bay.
Mercury Outboard and MerCruiser Service, Plymouth MA
Mercury Marine engines run on a large share of the boats you see across Cape Cod Bay, the Cape Cod Canal, and Buzzards Bay. The Mercury outboard lineup includes the FourStroke, Pro XS, Verado, the commercial SeaPro, and the electric Avator, while MerCruiser is Mercury's sterndrive (inboard/outboard) line. Many of these engines run SmartCraft, Mercury's digital control and monitoring system.
Atlantic Boat Repair is an independent boat repair shop at 210 South Meadow Rd in Plymouth, MA. We service, maintain, and repower Mercury outboards and MerCruiser sterndrives. We are not a Mercury dealer, and we do not claim to be. What we are is a hands-on local shop that works on these engines every season and uses quality and genuine replacement parts.
Mercury outboards commonly power center consoles, dual consoles, bay boats, walkarounds, RIBs, pontoons, and bass boats, including New England fishing and family rigs from Boston Whaler and similar builders. MerCruiser sterndrives commonly power bowriders, cuddy cabins, runabouts, and deck boats from makers like Sea Ray, Bayliner, Chaparral, and Four Winns. We work on both.
This is saltwater country with cold New England winters, so corrosion, ethanol fuel problems, and fall winterization come with every season here. We keep Mercury and MerCruiser power reliable through the season and protected through the off-season, so you spend more time running and less time stuck at the dock.
