87-813960A3 MERCURY Neutral Switch Mariner

Review MERCURY 100hp 115hp 125hp Stroke Neutral Switch for MARINER

The Mercury 87-813960A3 CH5A Mariner Neutral Switch is a crucial component in the electrical system of Mercury outboard motors, specifically those with a power output of 100hp, 115hp, or 125hp. This neutral switch is engineered to provide safe and reliable operation by ensuring that the engine's power is only delivered to the propeller when the boat's gearbox is in neutral or reverse position.

The switch is designed with a compact and robust construction, making it ideal for use in marine environments. It is constructed from high-quality materials that can withstand the harsh conditions of the water, such as corrosion-resistant marine-grade plastic and heavy-duty contacts. The switch's design also includes a clear and concise LED indicator, which displays the engine's status, making it easy for operators to identify when the engine is in neutral or reverse.

The Mercury 87-813960A3 CH5A Mariner Neutral Switch is easy to install, and it can be mounted in various locations on the boat, such as the dashboard or the engine control panel. It comes with all necessary mounting hardware, making the installation process quick and straightforward. The switch also features a plug-and-play connection, which eliminates the need for complex wiring configurations.

The switch's operation is seamless and intuitive. When the boat's gearbox is in neutral position, the switch allows power to flow to the engine, enabling it to run. When the gearbox is shifted into reverse, the switch breaks the power circuit, preventing the engine from spinning in the opposite direction. This ensures that the engine does not cause damage to the boat or its surroundings when in reverse.

In summary, the Mercury 87-813960A3 CH5A Mariner Neutral Switch is an essential safety feature for Mercury outboard motors. Its robust construction, easy installation, and intuitive operation make it an indispensable component for boaters who value safety, reliability, and ease of use. Whether you're a seasoned boater or a novice, this neutral switch is an investment that will give you peace of mind and enhance your boating experience.
