White panel with black lettering.


Both Catalina Yachts and Seaward report thousands of boats were built using this shape panel. But there is not a detailed history of the engine panel used on each boat built. Please check the dimensions of your panel to ensure this panel is suitable for your boat. This panel is designed for use with a Universal Diesel engine. For boats equipped with a Yanmar diesel, see the Yanmar panel below shown under "May we also suggest".

• Height: 5-5/8"
• Width: 13-1/2"

1) Early engine installations were wired to use an ammeter in the instrument panel. The entire alternator output was routed through the instrument panel. This added many feet of wire to the circuit. The added resistance reduced the voltage that reached the battery and the effectiveness of the charging system. A simple wiring change improved this system substantially. The circuitry of our new panel is designed assuming the change has been made to your boat. Do not install this panel until the wiring change has been made! Refer to the PDF below under "Technical Support" for complete instructions.

2) The tachometer is adjusted by our vendor to be approximately correct when installed on a boat equipped with an M25XP with standard factory installed alternator and pulleys. The reading can only be exact if calibrated after installation using a mechanical tach or strobe. All other engine installations require adjustment after installation of the tachometer to achieve reasonable accuracy.

3) Each tachometer is bench tested before it leaves our vendor. 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) 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.

5) 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.

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