## Customer Reviews

### ⭐ 







  
  
    Failed within 2 months
  

*by S***L on Reviewed in the United States on June 26, 2019*

Initially, this kill switch worked for a couple of times, then it failed. It took few weeks of time and effort in troubleshooting the problem. Since it was new, I never thought that this kill switch was the reason my outboard won't start. I unnecessarily spent money on the new ignition switch and CDI power pack. Also, the lanyard plastic key which goes into the kill switch was poorly quality. It cracked on the very first use.

*by P***E on Reviewed in the United States on May 13, 2020*

The switch worked fine for about 20 minutes.  I stopped to fish and the engine wouldn’t start again.  After I was towed back to the dock and 3 hours of troubleshooting, not thinking it could be the brand new switch, I bypassed it and the engine fired up immediately.  Reconnected the switch and nothing.  Very unimpressed.....

    Works great

I used this to convert a push button tiller outboard (Johnson 9.9 2 stroke) to a lanyard style killswitch. It works fairly well for being a universal product. I was able to use a large washer to make it work on my 1985.
