STATOR YAMAHA 6E5-85510-11

Function and technical context

The stator is the fixed magnetic component of the electrical generation system of Yamaha outboard motors. It works in coordination with the rotor to produce the alternating current that powers the ignition system and other electrical circuits of the engine. Their correct operation is essential to maintain a consistent spark at the spark plugs and ensure reliable starting and stable operation of the engine under all boating conditions. A defective stator results in intermittent misfires, starting difficulties, or complete loss of electrical power.

When to replace this part?

Symptoms of stator failure include difficulty starting the engine even with a fresh battery, misfiring while cruising, unexpected shutdowns at specific rpm, or no spark at all from the spark plugs. It is recommended that the condition of the stator be checked during annual seasonal maintenance, especially if the motor has been exposed to prolonged exposure to salt humidity or has been left unused for long periods. Replacing the stator preventively when symptoms are detected avoids unforeseen breakdowns in navigation and prolongs the useful life of the entire ignition system.
