DISCONNECTOR 87-97682M
Description
Function and technical context
The 87-97682M disconnect is a critical component of the ignition cut-off system on marine outboard engines. This part acts as a safety switch that interrupts the electrical power to the motor quickly and reliably when the safety cord or emergency stop control is activated. Its correct operation is essential to comply with international nautical safety requirements, avoiding involuntary starts and guaranteeing immediate shutdown in emergency situations. The disconnector works in coordination with the ignition system and is essential for the protection of the navigator and the occupants of the boat.
When to replace this part?
The disconnect must be replaced when the engine does not stop correctly when the safety cord is activated, when the internal contact is worn and does not interrupt the circuit reliably, or if the switch has been impacted after an accidental fall from the boat. It is recommended to inspect this part during each seasonal maintenance and verify its operation before each outing, especially on frequently used boats. Replacing the disconnector preventively before an intensive sailing season avoids critical safety failures in sea conditions.
