SUZUKI STOP SWITCH 37800-93953

Function and technical context

The stop switch is the electrical component responsible for interrupting the ignition of the outboard motor, cutting off the signal to the ignition system to stop the propeller immediately and safely. It works within the ignition and engine control circuit, acting as a fundamental safety element both in docking maneuvers and in emergency situations. A stop switch in poor condition can prevent the engine from turning off or, on the contrary, cause involuntary stops while navigating, compromising both the safety of the boat and the integrity of the electrical system. This Suzuki switch with reference 37800-93953 has been manufactured to integrate precisely into the models of the Suzuki DT range, guaranteeing reliable and long-lasting performance.

When to replace this part?

The most common symptoms of a faulty stop switch are the inability to turn off the engine from the control panel, sudden and unexpected engine stops without apparent cause, or an intermittent response when pressing the stop button. It is recommended to check the condition of the switch during each seasonal maintenance, since continued exposure to humidity, salt and vibrations typical of the marine environment accelerate the deterioration of its internal contacts. Replacing it preventively at the first symptoms avoids being stranded or without stop control at sea.
