Universal Kill Switch
by Michael from Hastings, Minnesota on June 19, 2016
The kill switch was easy to install, it fit in the original hole for the kill switch on my 1977 Johnson 25hp and gave you two options for hooking it up, open or closed circuit. I would recommend this to any one wanting to update or replace a kill switch, if not only for the safety of having a tethered kill switch.

My other kill switch was going bad, and this one replaced it perfectly. It arrived quickly and I was able to install it and get my boat working correctly right away.

Great switch and durable quality
by Erik from Houston, Texas on October 08, 2012
I purchased this switch to replace an antiquated one that was having issues. I hooked this switch right in line with my current wiring and worked like a charm. The ability to kill the engine with yanking the lanyard or just pressing the button worked like designed. Great price and product.

Best price
by a Customer from Miami, Florida on August 27, 2011
Same exact product available locally for almost twice the price. I recommend iboats for their pricing on marine related products.

almost half the price including shipping!
by a Customer from Miami, Florida on August 08, 2011
Been looking to add one of these to my boat, but all of the local marine outlets charge upwards of 15-20 dollars for these. Even taking into account the shipping costs, I saved almost half!
