Displays engine speed at the helm on a non-EVC installation, reading an ignition pulse, an alternator W pulse or an inductive pulse depending on the engine.

⚠️ Common Signs of Failure

• Needle reading high, low or not at all
• Reading jumping or unsteady at a constant engine speed
• Hour counter stopped while the needle still works
• Backlight dim or dead
• Condensation or a fogged lens behind the glass

🛠️ Service Notes

• It matches the 4000 rpm tachometer 23715874 in size and weight, so the scale and the part number are what separate them
• The instrument can read an ignition pulse, an alternator W pulse or an inductive pulse, and the installation instructions supplied with the kit carry the code table for setting the correct rpm for the engine family
• Check the signal source, the earth and the gauge supply before condemning the instrument
• The range is built in two sizes - 85 mm and 52 mm - and is designed to fit Volvo Penta instrument panels. 85 mm gauges suit an 80 mm, 85 mm or 90 mm panel hole with the attaching ring and adapter rings included; 52 mm gauges suit a 52 mm or 60 mm hole with the included adapter rings
• If the panel already in the boat is not one of the Volvo Penta instrument panels in this range, the panel hole diameter may need to be modified to suit the new gauge's diameter
• A mounting kit for flush mounting can be ordered where it is needed; the kit contains the o-ring, fixing brackets and nuts
• For an industrial engine application where the instruments are connected to the CIU, the EasyLink instruments are the ones used instead
• Two rpm scales are listed: 23715874 is the 4000 rpm kit
• Set the correct rpm for the engine family using the code table supplied with the kit
