YAMAHA PULSATION COIL 66M-85533-00
Description
Function and technical context
The pulse coil is an essential component of the ignition system on small displacement Yamaha outboard engines. This part generates the electrical impulses necessary to activate the ignition system, allowing the spark to reach the cylinder at the exact moment. Its correct operation is essential to maintain efficient combustion, ensure reliable starts and guarantee optimal engine performance in all navigation conditions.
When to replace this part?
Symptoms of pulsation coil deterioration include difficulty starting, progressive loss of power, intermittent misfires, or an engine that runs irregularly at different speeds. It is recommended to inspect it during each seasonal inspection and replace it if signs of corrosion, humidity are observed or if the engine exhibits erratic ignition behavior. Preventive replacement prevents loss of seaworthiness and eliminates the need for costly emergency repairs.
