Review: Works great - My boat has an unregulated power supply from the engine (81 Johnson 50hp). So I'm not only worried about over draining the battery but also over charging. Since my fish finder has digital voltage read out this gauge is really just a backup in case my fish finder were to fail. I chose it because all my other gauges are also the same style from sierra and I like the cosmetic look of these gauges and they work great also. Never had an issue with fogging or water intrusion. I would like it if this gauge had a wider sweep so I could read the exact voltage easier. That being said this gauge does have lines running horizontally on both sides indicating a trouble situation if the needle is on them, over voltage on right or under voltage on left. This is actually surprisingly hard to find in volt gauges especially lines for over voltage. Some do have a red line indicating low voltage. Yet with those gauges their is nothing saying that over 14.5 volts is bad. I like this feature because its easy for me to explain to some one else that is using my boat what to watch out for instead of them having to remember specific numbers. Review: Does the job - voltmeter is working as expected, easy installation. Backlight makes it readable in the dark. ## Features - Black dial, red graduations, white numerals, vivid white pointer staff - Scratch resistant curved glass lenses, with black, near-flush bezels - Voltage: 12 VDC - Perimeter and thru-dial lighting - Requires hole size 2.13" ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000FQ1T5O | | Best Sellers Rank | #525,406 in Automotive ( See Top 100 in Automotive ) #180 in Automotive Voltmeter Gauges | | Brand | Sierra | | Brand Name | Sierra | | Customer Reviews | 4.7 out of 5 stars 194 Reviews | | Global Trade Identification Number | 00731957420084 | | Included Components | Voltmeter, Amega 2", 8-18 VDC | | Item Dimensions | 4.6 x 3.5 x 3.3 inches | | Item Type Name | Voltmeter, Amega 2", 8-18 VDC | | Item Weight | 1.44 ounces | | Item dimensions L x W x H | 4.6 x 3.5 x 3.3 inches | | Manufacturer | SeaStar Solutions | | Material | Glass | | Material Type | Glass | | Model | 57901P | | Number of Items | 1 | | Part Number | 57901P | | UPC | 731957420084 | | Unit Count | 1 Count | | Warranty Description | Limited Warranty | ## Product Details - **Brand:** Sierra - **Item Weight:** 0.2 Pounds - **Item dimensions L x W x H:** 4.6 x 3.5 x 3.3 inches - **Material:** Glass - **Number of Items:** 1 ## Images ![Sierra 57901P Voltmeter - Amega 2", 8-18 VDC - Image 1](https://m.media-amazon.com/images/I/8143R862qnL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by R***R on August 17, 2019* My boat has an unregulated power supply from the engine (81 Johnson 50hp).
