Kawasaki 900 1100 Jet Ski Ignition Coil #3
This ignition coil replaces Kawasaki OEM 21121-3710. This is Coil #3 with a 26-inch wire length in the three-coil ignition system used on Kawasaki 900cc and 1100cc 2-stroke triple-cylinder Jet Ski models. Each cylinder has its own dedicated ignition coil that receives a trigger signal from the CDI unit and generates the high-voltage spark needed to fire the spark plug. When a coil fails, that cylinder loses spark, causing misfires, rough running, or a dead cylinder. The related coils are 21121-3709 (Coil #2, 21-inch wire) and 21121-3710 (Coil #1, 26-inch wire). Direct plug-in replacement with factory connector.
