Real-World Testing: Putting Sierra International MP40960 MP40960 Emergency CutOff Switch to the Test
First Use Experience
I first tested the Sierra International MP40960 Emergency CutOff Switch on my 18-foot center console during a fishing trip in Tampa Bay. The conditions were fairly typical for Florida: hot, humid, and with the occasional splash from choppy water. Installation was straightforward, fitting directly into the existing mounting location from my previous switch.
The switch worked flawlessly from the first pull. A firm tug on the lanyard immediately killed the engine, providing reassurance that it would function as intended in an emergency. I found the lanyard easy to attach to my clothing and long enough to allow for reasonable movement around the helm.
Extended Use & Reliability
After several months of use, the Sierra International MP40960 Emergency CutOff Switch has proven to be a reliable piece of equipment. There are no signs of corrosion or degradation, despite regular exposure to saltwater spray and intense sunlight. I make sure to rinse it with fresh water after each trip, which helps maintain its functionality.
The switch still provides a firm and positive action. The lanyard continues to be durable. This switch is a significant improvement over my previous corroded switch; I now feel much safer knowing that my emergency cutoff is reliable.
