Review: Perfect fit - Perfect fit. Maybe took 30 min or less to Install. Boat fired right up
Review: High quality ignition switch - This product is amazing. This fit our ‘87 Sea Ray Seville and installation was easy and straightforward. To me since we got the boat recently , this switch works way better than the previous switch. The wiring was 1:1 for my specific model did not need to change any of the wiring contacts or modify the wiring in any way. Mine was a combination of 0.25” spade connectors for the ignition and switch wires , however, needed to use the screw connector for the battery wires. I had 3 wires for battery. Also, another thing to note is that our boat has a separate switch for the accessory power for the radio, so there is no need to connect to the accessory connector on the switch. Overall great product and fit exactly in place and works better than before !

I had to replace the one that fell apart on the lake. I just took photos and googled brands and this one had the same look and same connectors as the old one. Easy to install and works!
