Buying Guide
Key factors to consider when choosing an ignition kill switch lanyard:
- Compatibility: Confirm the exact model or brand compatibility (Yamaha, Mercury, ToHatsu, Mercruiser, etc.).
- Length and stretch: Decide whether a shorter coiled length or a longer, extendable tether suits your boat’s layout and safety needs.
- Durability vs. weight: Look for durable materials (nylon PU, aluminum clips) that endure saltwater, UV exposure, and frequent handling.
- Attachment mechanism: Ensure the clip or buckle securely attaches to your clothing or life jacket and won’t detach unintentionally.
- Number of pieces: If you operate multiple boats or share gear, a multi-pack can be cost-effective and convenient.
- Safety coverage: Understand that lanyards improve safety but are not a guarantee against all engine failures or corrosion-related issues.
