In 2002, the question was asked if the Smartcraft gauges for the Mercury 4-Stroke EFI motors were worth the money. A response stated that the 2002 models were not rigged with the digital sending units required to operate the gauges nor was there a provision in the engine wiring harness to add sensors. Has any of this information changed since 2002? I have a 2004 50 HP Bigfoot 4-Stroke EFI motor and would like to add gauges to monitor engine temperature and oil pressure.
