ABYC certification exam guide (2026)

All 10 exams at a glance

Eight of the 10 count toward Master Technician or Master Advisor (three certifications needed). Service Management and USCG Recreational Boat Regulations don't.

Delivery and fees

• Every exam is taken with a proctor: online through a remote proctoring service (computer with webcam and microphone, Google Chrome, a single monitor and government-issued ID), or at the end of an ABYC class.
• Exam only (self-study route): US$295 for ABYC members, US$595 for nonmembers, per attempt. Service Management is sold as an online course (US$1,475 member, US$2,250 nonmember); ABYC doesn't publish an exam-only price for it.
• Marine Composites and A/C Refrigeration are available only as self-study with a proctored exam. Marine Standards, Advanced Marine Electrical, Service Management and USCG Regulations have on-demand courses.
• Study guides are sold separately: US$85 for members, US$175 for nonmembers.
• Class fees vary by course and host. Check ABYC's class calendar.
• Reference-material rules aren't stated on ABYC's public pages, except that the Service Management exam is not open book. Confirm the rules with the ABYC Education Department when you book.

What each exam tests

• Marine Electrical: DC and AC systems, wire sizing, overcurrent protection, batteries, chargers and inverters, shore power, ELCIs, galvanic isolators, generators, troubleshooting (E-11, E-10, E-13, A-27, A-28, A-31, A-32, E-2, A-24, TE-4).
• Marine Systems: fuel, water, sanitation, ventilation, LPG, thru-hulls and seacocks, exhaust, steering and controls, fire protection, A/C and basic electrical (H-2, H-22 to H-25, H-27, H-32, H-33, A-1, A-4, A-6, P-1, P-14, P-28 and more).
• Marine Corrosion: electrochemistry, the galvanic series, galvanic and stray-current corrosion, cathodic protection and corrosion surveys (E-2, E-11, A-28, T-1).
• Marine Engines & Fuel Systems: engine principles and the standards for fuel, ventilation, exhaust, electrical, cooling, controls, steering and drives (H-24, H-33, H-2, P-1, P-4, P-6, P-14, P-17, P-21, P-28, A-33, E-10, E-11, E-13).
• Marine Standards: how ABYC standards are organized and how to apply them, across 54 of the most-referenced standards, from electrical and fuel systems to capacity, buoyancy, navigation lights, heaters and boat lifting.
• Advanced Marine Electrical: diagnostics, control circuits, three-phase power, power quality, voltage regulation, solar, wind and hydro charging, AC power conversion and paralleling, electric propulsion, digital switching and fail-safe galvanic isolation (A-32, TE-12, A-27, E-11, E-30, S-31, A-28).
• Marine Composites: single-skin and sandwich construction, reinforcements and resins, stringers, bulkheads, transoms and hull-to-deck joints, lay-up and molding processes, quality assurance and shop safety.
• A/C Refrigeration: refrigeration components and design, AC and DC electrical controls, ducting and air flow, cooling-water circulation, reverse-cycle systems and mechanical repair (A-6, E-11, H-22, H-27 and EPA rules in 40 CFR).
• Service Management (ABYC with the MRAA): shop structure, SMART goals, KPIs, the service process, recruiting and managing technicians, conflict, problem solving, customer satisfaction, facility management and safety rules.
• USCG Recreational Boat Regulations: the federal rules for new recreational boats, from defect notification, certification labels and HINs to capacity, flotation, electrical, fuel, ventilation, start-in-gear protection and navigation lights (46 U.S.C. Chapter 43, 33 CFR 179, 181, 183).

Why candidates fail

The cut scores leave little room: on Marine Electrical you can miss only about 34 of 204 questions. Experienced technicians often know how to do a job well but not the exact number a standard sets (a distance, a trip level, a voltage drop percentage). The exam rewards precise knowledge of the standards, plus the pace to answer about one question a minute for three and a half hours.

An 8-week plan

1. Weeks 1-2: take the free practice test, then study the core material for your exam (E-11 for Electrical, the H-series fuel standards for Systems, E-2 for Corrosion, 33 CFR 183 for USCG Regulations, A-6 and the refrigeration cycle for A/C). Flashcards daily.
2. Weeks 3-5: work through the remaining topics two at a time: notes, then question sets.
3. Week 6: first full timed mock exam; drill your weakest topics.
4. Weeks 7-8: second full mock, clear your mistakes bank, and light review in the last two days.
