SEAflex Wiring Kits

Product Description Upgrade your boat’s electrical system with a SEAflex marine wiring kit—precision-matched components, zero guesswork. SEAflex kits are engineered for salt-water reliability and DIY simplicity. Components arrive pre-matched by gauge and terminal type, eliminating trial-and-error on install day. Primary wire is ABYC-compliant and ultra-flexible for tight helm spaces. We include the protection devices, lugs and jumpers pros use, so you can complete a clean, code-ready wiring job without last-minute parts runs. Three levels to match your build: Deckhand — essential terminals, 25 ft primary leads and 10-gang blocks—a perfect match for our SEAready switch panels. Mariner — adds 8AWG pre-made battery cable, jumper wires, a 100 A breaker and easy-ID fuse kit for multi-circuit consoles. Admiral — flagship kit with 350′ of marine grade wiring, including heavy-duty 6 AWG, duplex 14 / 16 AWG, twin breaker blocks and 13×3 heat-shrink labels for a yacht-grade finish. Why SEAflex outperforms generic boat wiring kits Hassle-free installs – components are pre-matched by gauge and terminal type, so parts fit together the first time. OEM-grade craftsmanship – every connector, breaker and spool is sourced to the same spec we supply to leading boat builders. Marine-proven durability – corrosion-resistant metals and adhesive heat-shrink seals keep circuits solid season after season. Smart, waste-free bundling – you get the exact counts needed for small skiffs up to blue-water cruisers—no leftover clutter, no emergency store runs.
