Flounder Pounder Marine put together a kit with standard switches that replaces the EIM. It’s about $1500 https://www.searay-parts.com/EIM-Replacement-System-p/sr-panel-eim-240-260sdda.htm
Was getting the electronic switch controller (“peanut shaped” controller) an option? My 2005 240sundeck has traditional switches, thankfully, and I’m wondering how I got so lucky. Not sure if was an option or a production change.
