Frequently Asked Questions
Common questions about marine wire harnesses
What makes tinned copper better for marine applications?
Tinned copper has a protective tin coating that prevents oxidation and corrosion in saltwater environments. Standard bare copper will corrode rapidly when exposed to moisture and salt, while tinned copper maintains conductivity and connection integrity for years.
What is the difference between IP67 and IP68 waterproof ratings?
IP67 means protected against immersion up to 1 meter depth for 30 minutes. IP68 provides protection for continuous submersion beyond 1 meter (depth specified by manufacturer). We offer both ratings depending on your installation requirements.
Are your marine harnesses built to ABYC E-11 standards?
Yes, all marine wire harnesses are manufactured following ABYC E-11 standards for AC and DC electrical systems on boats. This includes proper wire sizing, color coding, terminal crimping, and strain relief requirements.
Can you manufacture harnesses for specific boat brands?
Absolutely. We manufacture harnesses compatible with all major boat brands including Bayliner, Sea Ray, Boston Whaler, Grady-White, and custom yacht builders. Send us your specifications or existing harness for reverse engineering.
What is the lead time for custom marine harnesses?
Prototypes: 2-3 weeks including waterproof testing. Small production runs (50-200 units): 3-4 weeks. Volume production (500+ units): 4-6 weeks. Rush service available for emergency vessel repairs.
Do you provide installation documentation?
Yes, every marine harness includes: wiring diagrams, connector pin-outs, installation instructions, waterproof test reports, and material certificates. Digital documentation available for fleet installations.
How do I maintain marine wire harnesses?
Inspect connectors annually for corrosion, spray with corrosion inhibitor (CRC or Boeshield), ensure strain reliefs are secure, check for UV damage on exposed cables, and verify all seals remain intact. Replace any damaged components immediately.
What wire gauge should I use for my boat?
Wire gauge depends on current load and cable length per ABYC standards. For example: navigation lights (18 AWG), bilge pumps (14-16 AWG), windlass (4-6 AWG), starter cables (2/0-4/0 AWG). We provide free wire sizing consultation.
Can you supply complete electrical panels?
Yes, we manufacture complete marine electrical panels including switch panels, circuit breaker boxes, and distribution panels with pre-wired harnesses. Custom layouts available for new builds and retrofits.
Do you offer marine battery cables?
Yes, we manufacture heavy-duty marine battery cables with tinned copper conductors, marine-grade lugs, heat-shrink insulation, and proper sizing per ABYC A-31 battery installation standards.
What warranty do you provide?
24-month warranty against manufacturing defects including: crimping failures, seal leaks, conductor breaks, and material degradation. Does not cover damage from improper installation, physical abuse, or lightning strikes.
How much do custom marine harnesses cost?
Pricing varies by complexity: Simple engine harnesses $80-$150. Navigation system harnesses $120-$250. Complete vessel rewire harnesses $500-$2000. Contact us with specifications for accurate quote within 24 hours.
