OurPCB is a premier marine wire harness manufacturer. OurPCB makes full assemblies that work extraordinarily well with marine electronics because we meet ABYC standards and CFR Title 33 regulations for saltwater spaces. Marine electrical failures cause major safety issues and really expensive repairs.
On the other side of things, standard automotive harnesses give up pretty quickly from saltwater corrosion and vibration. We keep assembly standards with resilient materials like tinned copper conductors to stop electrical failures from happening.
Marine wire harness manufacturing is the production of wire harnesses that are made to handle saltwater, vibration, and intense temperature changes around boats. They package a bunch of different electrical wires with protective materials. These can be corrugated tubes, braided sleeves, and more. A wiring harness for boat applications sends electrical signals and power throughout vessel systems. It does this while protecting connections from corrosion, moisture ingress, and stress.
Marine wire harness designs need a minimum of 16 AWG tinned copper conductors with stranded construction for flexibility and corrosion resistance. All wires must meet a 50V DC minimum rating with a standard 600V voltage rating and 105 °C insulation for continuous operation. Engine compartment applications require 75 °C minimum temperature rating with oil resistance and flame-retardant properties meeting marine fire safety specifications.
Professional wire harness manufacturing follows IPC-620WHMA assembly standards, ensuring consistent quality and reliability. Assemblies must comply with ABYC standards and mandatory CFR Title 33 regulations, including proper wire identification through color coding and voltage drop limitations of 3% for essential circuits and 10% for general purpose applications.
Marine wire harness manufacturing delivers critical advantages for vessel electrical systems by providing superior environmental protection, regulatory compliance, installation efficiency, and long-term reliability.
OurPCB combines advanced PCB manufacturing expertise with specialized marine wire harness capability delivering fully integrated electrical solutions. Our ISO 9001-certified facility maintains stringent quality control processes and employs marine-specific testing equipment, including hydrostatic chambers and megger insulation testers.

High-quality wire harnesses utilize specialized materials including corrugated tubes for abrasion protection, braided sleeves for electromagnetic shielding, and silica sleeves for high-temperature applications. Twisted pair construction maintains signal integrity for communication systems while duplex and triplex cables with outer jackets provide additional protection.
Advanced manufacturing techniques include molding processes for custom connector solutions and multi-conductor cable assemblies for complex marine electrical systems.
Each final product receives comprehensive testing including electrical continuity verification, insulation resistance measurement, and environmental exposure validation. Documentation packages include assembly drawings, parts lists, wiring diagrams, test certificates, and certificates of conformance meeting IPC-620WHMA professional standards for top-quality marine applications.
OurPCB specializes in marine wire harness solutions for defense industry applications including naval vessels, submarines, and military marine equipment. Submarine applications require extreme pressure resistance with specialized materials and super-absorbent polymers for pressure control in deep-water environments. Our harnesses meet stringent military specifications for vibration resistance, electromagnetic compatibility, and performance in combat conditions.
Marine electronics integration requires specialized knowledge of NMEA 2000 networks, CANbus protocols, and marine-specific signal requirements. Wire harness assembly accommodates differential signaling for GPS navigation systems, radar displays, and fish finder equipment while maintaining proper impedance control. Marine communication systems including VHF radios and satellite communication require shielded cables with proper grounding to prevent interference.
OurPCB’s marine wire harness manufacturing facility features specialized equipment including hydrostatic test chambers rated to 200 PSI, automated wire cutting and stripping systems with 0.1mm precision, and ultrasonic welding equipment for marine connector assembly. Our quality control laboratory maintains calibrated megger testers, salt spray chambers, and vibration test equipment meeting ASTM standards for marine applications serving various industries including defense, commercial, and recreational boating.
