Buying Guide for Boat Ignition Switches
Compatibility
Ensure the ignition switch matches your boat motor’s make, model, and year. OEM part numbers and motor horsepower (HP) ratings typically guide compatibility. For Mercury, Johnson, and Evinrude engines, verify part numbers such as 87-88107, 5005801, and 87-17009 series to avoid purchase errors.
Switch Type and Functionality
Consider whether you want a standard Off-Run-Start key switch or one with additional features like push-to-choke that simplifies engine starting. Safety lanyard options provide extra protection by shutting off the engine if the operator falls overboard.
Build Quality and Corrosion Resistance
Marine environments are harsh; choose switches made with corrosion-resistant materials like marine-grade polyester or brass to extend longevity and performance. Non-conductive housing can prevent short circuits.
Wiring and Terminal Configuration
Check the number of terminals (often 6 for push-to-choke models) and wiring compatibility to ensure easy installation without rewiring your boat’s electrical system.
Durability and Maintenance
Heavy-duty switches withstand harsh use and vibration better, reducing the need for frequent replacements. Look for sturdy construction and sealed components to prevent water ingress and corrosion.
