Our gauges are water resistant but NOT waterproof.
Many customers have used their Speedhut gauges in motorcycles, boats, snowmobiles, and other vehicles without issues. As long as the gauges are kept out of inclement weather and direct contact with water is kept to a minimum, they should operate perfectly!
If you would like additional protection, we can add a rubber gasket underneath the gauge window to help keep water out. Add a comment during checkout that you would like a gasket added to your gauges, and we will add it to your order for free!
