Marine Electrical
Wiring, batteries, electronics, and shore-power systems.
Marine electrical work is its own discipline — saltwater corrosion, galvanic isolation, and DC-AC system integration all matter in ways automotive electrical doesn't. Look for an ABYC-certified marine electrician (American Boat & Yacht Council) for anything beyond basic wiring. Common jobs: battery bank upgrades to lithium, shore-power inlet replacement, navigation electronics installation, and corrosion troubleshooting.

Frequently asked questions
- What does ABYC certification mean?
- The American Boat & Yacht Council certifies marine technicians on standards specific to boats — DC/AC integration, corrosion, fuel systems, etc. ABYC-certified electricians follow industry-recognized safety standards that insurance companies often require for major work.
- Should I switch my boat batteries to lithium?
- Lithium (LiFePO4) batteries weigh ~70% less than equivalent AGM, last 5–10x longer, and recharge much faster. Trade-offs: 3–4x upfront cost and a properly designed charging system to avoid damage. Most marine electricians recommend lithium for boats spending significant time off-shore-power.
