TXRXIZ Universal Boat Safety Lanyard Kill Switch
The TXRXIZ universal lanyard is designed to fit most kill switches with its seven-key system, making it a versatile choice for Mercury, Yamaha, Honda, Tohatsu, Johnson, Evinrude, Suzuki, and jet skis. It combines PU rope with a durable ABS clip and features elasticity for a comfortable fit that reduces snagging. This option is best for boaters who own or operate multiple brands or plan to upgrade to a single safety lanyard across a mixed fleet. A potential limitation is that key alignment must match the current kill switch to ensure reliable engagement.
Best for: Multi-brand boats and owners seeking a single, universal solution.
Why selected: High compatibility with common brands and robust construction.
Caution: Check your kill switch key compatibility before use to avoid mismatch.
