IAC Survival Kit for 600SCi, 662SCi, 700SCi ApplicationsĀ 

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.

The advantage of the harness is to prevent a failed IAC from damaging the PCM, which is $2,000+ to replace. The harness contains a replaceable fuse that will blow and prevent the shorted IAC from damaging the PCM (ECU-Computer). This is a common failure point blamed on the IAC but the root problem isn't the IACs, it's the fact that Mercury is exceeding the duty cycle on many of the engines that causes them to overheat and short out.
