The Marine Design Corporation IAC Survival Kit is designed specifically for  Mercury Racing 600SCi, 662SCi and 700SCi engines.  Our kit eliminates  costly PCM damage that can occur when an IAC fails, which can be a common occurance.   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 USA made IAC units with gaskets, hardware, (just in case you drop one in the bilge) spare fuses and a canvas storage pouch.  Replacement IACs and fuses are also available. 

IAC Survival Kit $299.00 each

Replacement IAC with fuse $69.00
