I purchased quite a few gauges from a gentleman that use to work on boats.  Check out my other items. Some are new some are used, he said they all are functional. I can't tell if this is new or used. I put used in the listing descriptions. The hole diameter is 2-1/16" overall with bezel it's 2-1/4". There is a spot for a 12V light to mount. I don't have the light. The bracket is there it's missing 1 nut.  It will be packaged well.
