Mobile Diesel Marine Mechanic

at Johanson Boatworks in Rockland, Maine, United States

Job Description

Johanson Boatworks, a True Course Capital portfolio company, is hiring a Mobile Marine Diesel Mechanic to serve customers across midcoast Maine.

  • Johanson Boatworks, a True Course Capital portfolio company
  • Location: On site, 11 Farwell Drive, Rockland, ME 04841
  • Employment Type: Full-time, year-round
  • Pay: $70,000 - $90,000 annually, depending on experience and certification

About the Role

This is our mobile service position. You work out of a fully equipped company service vehicle, handling repairs and maintenance at customer boats in Rockland, Rockport, Camden, and surrounding harbors. You solve problems on your own, without a shop full of colleagues to lean on.

You are also the face of Johanson Boatworks in the field. The customer you help today may book a haul-out, restoration, or winter storage with us tomorrow. This role combines technical skill with a sales mindset, and we pay for that combination.

What You'll Do

Field Service

  • Diagnose and repair marine diesel engines and systems dockside and on the hook - Perform scheduled maintenance, winterization, and commissioning in the field
  • Troubleshoot fuel, cooling, exhaust, and electrical systems independently
  • Manage your own route, parts, and job sequencing
  • Maintain the service vehicle, its inventory, and its tooling

 

Customer Facing

  • Represent JBW to owners, captains, and brokers
  • Identify additional service needs and communicate them clearly and honestly
  • Bring yard work back to Rockland: haul-outs, storage, restoration, and larger projects
  • Support sales calls alongside service visits
  • Keep accurate records of work performed and customer conversations

 

What You Bring

Required

  • Strong hands-on marine diesel experience with proven independent diagnostic ability
  • Genuine self-sufficiency. You will solve problems alone, on someone else's boat, without backup.
  • A sales-oriented mindset and comfort in customer conversations
  • Clean driving record and valid driver's license
  • Own hand tools
  • Ability to work in confined spaces and on the water

 

A Strong Plus

  • ABYC certification
  • Factory training on Yanmar, Volvo Penta, Westerbeke, Cummins, or Caterpillar marine engines
  • Prior mobile or field service experience
  • Marine electrical, generator, or hydraulic experience
  • Local knowledge of midcoast Maine harbors

 

What We Offer

  • $70,000 - $90,000 annually
  • Fully equipped company service vehicle
  • Autonomy over your route and your day
  • A visible role. You represent the yard, and that is recognized in the pay.
  • Paid time off and a tool allowance
