DISCONNECTOR 87-93102M
Description
Function and technical context
The 87-93102M disconnect is a stop switch that is part of the ignition cut-off system on Mercury, Mariner, Mercruiser and Yamaha marine engines. This component is responsible for interrupting the ignition circuit when the emergency stop button is pressed, guaranteeing immediate shutdown of the engine in critical situations. It is a fundamental element in the boat's safety system, since its direct reliability affects the ability to respond to emergencies and the protection of both the crew and the boat.
When to replace this part?
A defective disconnector is manifested by the inability to turn off the engine using the stop button, slow response of the cutting system, or corroded internal contacts that prevent the correct conduction of the stop signal. Although this type of component does not have a fixed maintenance interval, it is advisable to check its operation at least once at the beginning of each navigation season. Preventatively replacing this switch avoids being left without emergency shutdown capability at sea, a situation that can seriously compromise navigational safety.
