YAMAHA STATOR 6EK-81410-00

Function and technical context

The stator is the fundamental component of the current generation system in Yamaha outboard motors. It is a factory one that is part of the alternator, responsible for producing the electrical energy necessary to power the ignition systems, instruments and accessories of the boat. Working in close coordination with the rotor, the stator generates the magnetic field that transforms the mechanical energy of the motor into electrical current. A worn or defective stator reduces the charging capacity of the battery, directly affecting the reliability of ignition and the operation of critical electrical equipment on board.

When to replace this part?

The most common symptoms of stator failure include difficulty starting the engine, progressive weakening of the battery, failure of on-board instruments or loss of power in auxiliary electrical systems. Although there is no fixed maintenance interval for the stator, it is recommended to check its condition during the boat's annual services, especially if anomalies are detected in the battery charging or alternator operation. Preventively replacing the Yamaha 6EK-81410-00 stator guarantees reliable generation of electrical energy and avoids unexpected breakdowns while sailing.
