MAP Sensor Mercruiser 854445

123-9-33603

MAP Sensor
Replaces: Mercruiser 854445
Fits: MCM 525 EFI

Malfunctioning MAP sensors can often cause problems, such as an intermittent check engine light, hesitation when accelerating, elevated emissions, and even poor engine performance. So, if yours is in need of replacement, do it with Mallory Marine MAP sensors. These MAP sensors provide precise measurements of manifold absolute pressure. They are designed to perform in harsh environments, such as extreme temperatures, vibration, thermal and mechanical shock, and chemical contamination. Safeguard your engine with these quality MAP sensor components.

IAC Survival Kit for Mercruiser and Mercury Racing Applications

$299.99

IAC Survival Kit for Mercruiser and Mercury Racing Applications

221-1090

The Marine Design Corporation IAC Survival Kit is designed specifically for Mercury Racing 600SCi, 662SCi and 700SCi engines but will work with many other applications. See the full list of compatible engines in the additional info section. 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 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.
