Author Topic:   Gauge Upgrade

I was thinking of upgrading my current tachometer to one that would display my new Evinrude E-TEC trouble lights. My other gauge is a speedometer that is questionably accurate at best. [Give] suggestions for an updated replacement for this gauge. Depth? Modern speedo? Anything cool and useful I could put in that space? [Will new gauges] fit in the same hole? Thanks.

If you have an E-TEC you want a System Check tachometer. Most gauges are made in standard diameters of 2-inch or 3.5-inch. Speedometers still use a Pitot tube measurement. How many holes are there to fill?

two holes. Assume speed is provided by GPS. Battery meter seems to be a decent utilitarian approach

If you have a GPS, why not set it up to display speed? Most
GPSs allow this.

I'm surprised the E-TECs don't support one of the more
sophisticated digital protocols like NMEA-2000. However, if
they don't you really want the System Check tach. It will
warn of overheat, and oiling problems.

The E-tech definitely offers sophisticated instrumentation options, so for sure I am getting the system check tach. I am just wondering what instrumentation options I have for where my speedo is currently. Speed and depth data will be provided by external device. I am thinking maybe, magnetic compass: kind of cosmetic, could be useful back up in a worst case scenario. Battery meter: the old motor had definite charging issues, less of an issue for E-tech as I have rope start, but still good info. Maybe I could slot a drink holder in there?

/aside: how do you tag links to get them in line, or at least clickable?

Chuck--The E-TEC was the first outboard engine to be certified for NMEA-2000. I think that was back in 2005, or perhaps earlier. But the E-TEC is flexible and works with conventional gauges, too.

There really is only one sophisticated digital protocol for recreational boats: NMEA-2000. It's the only widely used protocol. All engine manufacturers support it now, and everyone but Mercury provides native support for it. (With Mercury it is a $700 up-charge to get NMEA-2000 support.)
