Corrosion Protection
Salt air and water are the enemies of electrical connections. Our marine harnesses use proven materials and techniques to resist corrosion and maintain reliable connections.
Tinned Wire
Prevents copper corrosion from salt
Sealed Connectors
Waterproof connection points
UV Protection
Jacketing resists sun degradation
Strain Relief
Prevents damage from vibration
Marine Wire Harness Manufacturing for Boats and Ships
As a specialized marine wire harness manufacturer, OurPCB delivers corrosion-resistant cable assemblies for boats, ships, and offshore applications. Our wire harness expertise covers tinned copper conductors, waterproof assemblies with IP67/IP68 ratings, and harsh environment cable solutions for salt spray, vibration, UV, oil, and wash-down exposure.
Marine engine harnesses connect controls, sensors, and instrumentation in harsh saltwater environments. Deutsch connectors provide excellent sealing for engine room applications. Navigation system cables connect GPS, radar, chart plotters, and data systems on the helm.
Electrical system harnesses handle DC power distribution (12V, 24V, 48V), battery connections, and shore power interfaces. Power cables support both AC and DC marine systems. Sensor harnesses monitor engine parameters, fuel levels, and environmental conditions.
Deck equipment cables connect winches, windlass, thrusters, and hydraulic systems exposed to weather and wash-down. Heat shrink sealing and strain relief construction prevent water intrusion. Our oil and gas expertise extends to offshore platform applications.
We support boat builders, marine OEMs, and system integrators with production volumes and prototype development. Our testing capabilities verify electrical performance. Contact us for marine wire harness quotes for your vessel or offshore application.
From the Case Bank
A US marine OEM sought a new supplier for custom wire harnesses and audio systems, initiating a rigorous multi-month evaluation process involving multiple business units.
The customer issued 6 separate RFQs over two months and engaged in a 64-email deep-dive technical thread, demanding strict weekly delivery, tariff mitigation, and cost competitiveness compared to incumbent suppliers.
Maintained rapid response times (1-2 days), proactively proposed a buffer stock strategy (advance ordering) to meet weekly delivery needs and mitigate tariff risks, and transparently presented alternative material options with cost benefits.
Successfully navigated the extensive qualification process, secured the tooling order, and transitioned into the prototyping phase for mass production.

Marine FAQ
Marine-grade harnesses use tinned copper conductors for corrosion resistance, UV-resistant and moisture-resistant insulation, waterproof connectors, and materials that withstand salt spray and marine environments. We follow ABYC standards for marine wiring.
We manufacture harnesses with IP67 (temporary immersion) and IP68 (continuous immersion) ratings using sealed connectors and proper sealing techniques. Specific protection levels depend on application requirements.
Yes, we manufacture harnesses for both DC (12V, 24V, 48V) and AC (120V, 240V) marine electrical systems. We use appropriate wire gauges, insulation ratings, and connectors for each voltage level and application.
We work with boat builders, marine OEMs, and system integrators. Our capabilities include prototype development, production volumes, kitting services, and custom harness design to meet specific vessel requirements.
