Mercury Marine offers 42-function color gauge
Three versions of MercMonitor are offered: Basic MercMonitor, MercMonitor with RPM SmartTow, and MercMonitor with SmartTow Pro.
MercMonitor has an engine-detection system that automatically determines the boat's engine type and configures the gauge appropriately. Additionally, MercMonitor's 42 functions can be programmed to appear in groups of three in as many as five configurations. MercMonitor's face consists of three information segments, and any of the functions can appear in groups of three.
MercMonitor is a 3 3/8-inch round gauge, and can be fitted for engine models dating back to 2002. Available colors include blue, yellow, red, purple, green and teal, and every gauge can be programmed to show any of the colors.
