Used on the Catalina 350 when equipped with a Westerbeke / Universal M-35BC engine.

Click on the link to the Detailed PDF below for a copy of the drawing which shows the original panel for which this will be a replacement. Dimensions and fittings are the same although the text and labels may have been altered for better visibility.

• Height: 4.75"
• Width: 13.5"
• Mounting holes: 6

1) There are dozens of different engine panels that have very subtle differences. For example, sometimes the difference is only 1/4" in overall dimensions or there may be a single change in the devices fitted to the panel. Always measure and compare both features and dimensions to your existing panel to ensure this item will meet your requirements before ordering.

2) A fine calibration potentiometer is under the sticker at the back (see "More Images" below). It is a delicate electronic device mounted to the far side of the circuit board with three soldered on contacts. The adjustment is accessible through a small hole in the board. A watch maker can successfully adjust it without damaging it or pushing it off of the circuit board. Our experience indicates that mechanics are too ham-fisted and will break it every time. If approximately correct isn't accurate enough for your needs, you can attempt to adjust it using a jeweler's flat blade screwdriver (not phillips head). But once you remove the sticker over the calibration screw, the warranty is void and the tachometer cannot be returned.

3) Each tachometer is bench tested before it leaves. This leaves the indicator at a position other than zero. Once you install the tachometer, the indicator will return to zero when the engine is stopped with the kill lever before the ignition is switched off.

4) Caution! Only use warm soapy water, no degreasers or harsh chemical cleaners, to clean the plastic panels.
