Greetings! How accurate are your electric gauges? Thank you!

Asked by: Phil G.
Hello! Our short sweep gauges have a tolerance of up to +/- (plus or minus) 5%. There are many additional factors like the thickness of the pointer and overall scaling and resolution of the gauge. Our Full Sweep Electric (Digital Stepper Motor) are more accurate and usually within about 2%.

I have an older set of Phantom gauges and need to replace 1 water temp gauge (5737). Can you get me the dimensions to be sure this will fit in my dash.

Asked by: Victorio
Victorio, Thank you for your question. This gauge uses the exact same hole size as 5737 which is 2-1/16". The diameter of the gauge is 2-1/4", depth is 1-1/2" to the back of the gauge, and 2-5/8" to the mounting studs.

Is the original Mercruiser sender ok to use with Autometer water temp gauge?

Asked by: Tord
Thank you so much for contacting us. An AutoMeter temp gauge will always need to be paired with an AutoMeter sending unit. It will not work with any OEM sender. This gauge should use the 2258 sender: Hope this helps!

are these gages available with chrome trim rings instead of black?

Asked by: brian2018
Hi Brain, thank you so much for contacting us. We could absolutely do a special order on this gauge to have it built with a chrome version of the Super Bezel it's equipped with. Give our team a call at 866.248.6356 and we can figure out the details for you. If you want something pretty close with a lower profile, chrome "street rod" bezel, you might want to check our this Arctic White gauge: Hope this helps!

Like picture of back. Replacing a Beede 944382 - it has 4 threaded studs (one mount, S,I,G & spade marked L) and one spade terminal. Will the #5737 work as a substitute?

Asked by: Rich
Thank you for the question. Unfortunately, we are not familiar with the Beede instrument. The 5737 Water Temperature gauge fits into a 2-1/16" diameter hole, features 2 mounting studs for the bracket we include, has 3 gauge connections required for operation; 12V, Ground, and Sender, and a standalone light socket that will require 12V and Ground. Most importantly, our gauge will require our sender 2258, which is included with the gauge. Here is a direct link to the instructions that will show a representation of the back:
