( Brand: Mercury Mariner ), ( Manufacturer Part Number: 879984A ), ( Part Type: Ignition Hp Coil ), ( Modified Item: No )
The 879984a Ignition Coil is a crucial component for your 2002 Mercury Mariner Outboard engine, especially if it falls within the power range of 30-250 HP. This ignition coil is designed to deliver a high-voltage spark to your engine's spark plugs, which in turn ignites the fuel-air mixture in the cylinders.
The 879984a Ignition Coil is a compact yet powerful device, measuring approximately 2.5 inches in length, 1.75 inches in width, and 1.25 inches in height. It is constructed with high-quality materials, ensuring durability and reliability under the harsh marine conditions. The coil is sealed to protect against moisture and corrosion, ensuring a long service life.
The ignition coil features a primary winding of copper wire, which is responsible for generating the low-voltage electrical current needed to excite the high-voltage secondary winding. The secondary winding, made of fine copper wire, creates a high-voltage spark that jumps the gap between the spark plug electrodes. The spark ignites the fuel-air mixture, causing a combustion that drives the piston down in the cylinder, ultimately turning the crankshaft and powering the boat.
Installing the 879984a Ignition Coil is a straightforward process. It simply replaces the existing ignition coil on your Mercury Mariner Outboard engine. The new coil comes with clear installation instructions, making the process easy for even the least mechanically inclined.
In conclusion, the 879984a Ignition Coil is a vital component of your 2002 Mercury Mariner Outboard engine, ensuring reliable and efficient engine performance. Its high-quality construction, compact design, and ease of installation make it an excellent choice for boat owners looking to maintain their engine's optimal performance.
