Upgrade your marine dashboard with the Faria 4” Tachometer with Hourmeter (4000 RPM), designed specifically for diesel engines using mechanical takeoff or variable-ratio alternator signals. This premium marine tachometer delivers accurate engine RPM readings while the built-in hourmeter tracks total engine run time—perfect for maintenance scheduling and performance monitoring.
Built for harsh marine environments, this 4-inch gauge features corrosion-resistant construction, clear easy-to-read markings, and reliable illumination for low-light conditions. Compatible with 12V and 24V systems, it’s an ideal replacement or upgrade for boats, yachts, and commercial marine applications.
Dual Compatibility: Engineered to work with both Mechanical Signal Generators and Variable Ratio Alternators.
Precision Calibration: Features an adjustable trim pot on the rear to fine-tune the RPM reading based on your specific pulley ratio.
Superior Visibility: Features a bold white dial, polished stainless steel bezel, and perimeter lighting for clear reading in low-light conditions.
Marine-Grade Durability: Built with a contoured glass lens to prevent fogging and a rugged housing to withstand harsh salt-air environments.
