Why Replace the Magneto Stator?

A failing stator is one of the most frequent causes of electrical breakdowns in Sea-Doo 4-Tec engines. The windings gradually deteriorate due to heat, humidity, or electrical overload. Common symptoms of a failing stator include:

Battery not charging while underway
Random engine cuts or sudden shutdowns
Ignition problems or difficulty starting despite a new battery
Burning smell from the engine compartment
Abnormal AC voltage measured on the stator wires

Preventive replacement is recommended at the first sign of unexplained electrical problems or during a complete overhaul of the ignition system. Always inspect and replace burned or corroded connectors during installation, and use high-temperature dielectric grease on all connectors.
