Hello all, looking for a little help. I am in need of a ICM part number
  • 861251T1 ICM MODULE
For a 04 4.3L Merc. I was hoping to find a used one for cheaper before I go out and order a new one for 600$

If that is not the case does anyone know of an upgraded system that would cost about the same amount and still be USCG approved? If I’m already spending the money I’d rather upgrade. Thanks!

Usually you can find them on eBay used, but as more icms have become NLA that is getting harder to find. Green Bay prop used to list a lot of used parts not sure if they can help.

If all else fails a delco est is a common replacement and is relatively drop in with minor wiring changes. The original delco is est is a OEM quality system, used on some VP and mercruiser engines from the factory. There are cheap knock offs out there that may or may not be of similar quality. Michigan Motorz sells est systems
