Re: help '97 force 120 temp gauge

The digital gauge you have listed does not include the gauge specific sending unit.

Here is another selection that does. Looks like the sending unit is 1/8 NPT thread which is what you need if you're going to use the fitting at the top of the block by the thermostat housing.

Here is another one that is the traditional analog needle sweep gauge. Kind of pricey, but has a temperature range that is suited to outboard motors, and includes the correct sending unit .

Most analog temp. gauges for automotive use start out at 100? - 120? F. Force outboards run in the 130? - 140? temp. range, so if you use one of these, the needle will barley move. The analog unit listed above works well as the normal running temperature for the Force motors puts the needle right in the middle portion of the scale on the gauge.

thanks for that. The Cyberdyne Digital Prism Gauge is just what i was looking for. When i install the gauge do i run the ground back to the block?

You should have a ground on your fuse panel under the dash. That should be good enough. You can run a separate ground to the block but it isn't necessary.
