Buying Guide
Key considerations when choosing a boat kill switch lanyard:
- Compatibility: check if the lanyard keys fit your engine brand and model. Universal keys save stocking multiple options but still require confirmation for your specific switch.
- Durability: look for PU cords, corrosion-resistant clips, and robust crimps. Marine environments demand materials that resist salt, water, and UV exposure.
- Length and coil design: longer cords provide better reach but can snag if too loose. A coil or elastic feature helps keep the line organized while in motion.
- Visibility: red or bright lanyards improve retrieval if dropped overboard and help others notice the safety tether.
- Ease of installation: consider whether the kit includes all hardware (clip, snaps, lanyard, and connectors) for a quick setup.
- Replacement options: if the original is worn, choose a model with straightforward replacement parts or widely available compatibility.
