Description
Function and technical context
The NGK BPR6EFS spark plug is part of the ignition system of the marine petrol engine, being responsible for generating the electric spark that initiates the combustion of the air-fuel mixture in each cylinder. Its correct operation is decisive to obtain complete and efficient combustion, which translates directly into power output, fuel consumption and engine emissions. Manufactured by NGK in accordance with its quality standards for nautical applications, this spark plug is designed to withstand the humidity, vibration and temperature conditions typical of the marine environment. Poor ignition caused by a bad spark plug causes loss of power, increased consumption, difficult starts and can lead to damage to the catalyst or the combustion chamber itself.
When to replace this part?
The most common symptoms of a worn spark plug in a marine engine are: costly or failed starts, jerking and loss of speed at full load, high fuel consumption and the appearance of black or white smoke in the exhaust. Spark plugs in marine petrol engines should be checked every nautical season and replaced, as a general rule, every 100 hours of operation or annually, whichever comes first, given that exposure to marine humidity accelerates their degradation compared to land applications. Replacing the spark plugs preventively during seasonal maintenance is a low-cost measure that prevents navigation breakdowns and protects the overall performance of the engine.
