About IAC Survival Kit

The Marine Design Corporation IAC Survival Kit is designed specifically for  Mercury Racing 496MAG, 496MAG HO, 600SCi, 662SCi and 700SCi, 1075/1200SCi engines.  Our kit eliminates  costly PCM damage that can occur when an IAC fails, which can be a common occurrence.   The kit was developed for twin engine applications and includes two plug-and-play IAC harnesses that are fused to prevent a direct short to the PCM.  Also  included are two Tier 1 OEM IAC units with gaskets, spare fuses and a canvas storage pouch.  Replacement IACs and fuses are also available.
