Engine sensors

[dmksails]

I have a Yanmar 3M30F engine. It has a tack and idiot lights in the cockpit and an hour meter hidden in a cabinet. I want to add actual sensors and gauges to the boat. Is there a max length for the cables from the sensor to the gauge?

Im thinking to locate the panel in the area of the chart table - some 6+ feet away.

Wire length does not matter unless the wire is part of the resistance measurement like in an EGT system. All your sensors will be doing their thing in the sensor itself
