Restore Dependable Ignition Performance with FASWORX Marine Components Don’t let a corroded or failing ignition switch strand you at the dock. The FASWORX 3-Position Push-to-Choke Ignition Switch is engineered specifically to withstand aggressive saltwater and freshwater environments. Serving as a direct replacement for Mercury/MerCruiser 87-88107A5, this assembly provides seamless plug-and-play functionality for your boat's remote control box or dashboard console panel. Engineered to Outperform OEM Standards Standard switches frequently fail due to internal moisture buildup and rust. FASWORX addresses these vulnerabilities with high-tier materials: Glass-Filled Polyester Housing: A rugged, non-conductive polymer shell that isolates electrical terminals and resists cracking under heat and mechanical stress. Heavy-Duty Brass Terminals: Delivers maximum conductivity and completely prevents the oxidation common with lesser metals. Integrated Weather Seal: A specialized internal barrier seals out rain and humidity, protecting the 12V internal contact plate for long-term reliability. Technical Specifications: Rating: Ignition 15A @ 12V DC | Solenoid 30A @ 12V DC | Choke 7A @ 12V DC Mounting: Fits a standard 7/8" hole, accommodating panels up to 5/8" thick Package Includes: 1 x Ignition Switch, 2 x Keys

• DIRECT OEM REPLACEMENT: Engineered as a precise drop-in replacement for Mercury Marine and MerCruiser part numbers 87-88107A5, 87-88107, 87-17393, and 88107A5. Universally fits most 1994 and newer side-mount remote control boxes and 6-wire potted console panels.
