The Nuova Rade 28138 Emergency Stop Wrench for Mariner / Suzuki / Johnson Marine Outboards consists of an expandable coiled cable with a release pin on one end and an ergonomic carabiner on the other end that connects to the life jacket of the boat. When a passenger falls overboard, the check is pulled out of the engine socket, stopping its operation. The model is a fundamental element to guarantee safe navigation.
