MAZUZEE 65 MPH Marine Speedometer Gauge – Dual Scale MPH/km/h is a reliable analog marine speedometer designed to provide clear and easy-to-read speed information for a wide range of boats. Available with either a black dial (JY18203) or a white dial (JY18303), this 85mm gauge features a dual-scale display with speed readings in both MPH and km/h, making it suitable for boat owners who prefer either measurement system. The clean dial layout, bold markings, and contrasting needle help improve readability during daytime operation, while the integrated yellow and orange illumination enhances visibility in low-light and night-time conditions. Designed for 12V and 24V electrical systems, the gauge can be used on many different marine electrical setups without requiring separate versions.

A boat speedometer is an important instrument for monitoring vessel speed while underway. It helps operators maintain appropriate cruising speeds, navigate regulated waterways, monitor performance, and improve overall boating awareness. The MAZUZEE speedometer gauge is designed with a standard 85mm diameter, allowing it to fit dashboards that accommodate this gauge size. Its classic round design integrates neatly into marine instrument panels alongside tachometers, fuel gauges, voltmeters, trim gauges, and other essential navigation instruments. The dual-scale MPH gauge offers convenient speed reference without requiring conversions between imperial and metric units, making it suitable for boat owners who operate in different regions or simply prefer having both measurements available.

The gauge is available in two attractive dial finishes to complement different helm styles. Model JY18203 features a black dial for a modern appearance with high-contrast markings, while Model JY18303 features a white dial that provides excellent visibility in bright daylight and matches lighter dashboard layouts. Both versions include the same speed range, dial layout, electrical compatibility, lighting colours, and overall dimensions, allowing customers to select the appearance that best matches their vessel’s dashboard. The integrated yellow and orange backlighting improves visibility during early morning departures, evening cruises, and low-light operating conditions while maintaining clear gauge readability.

Manufactured for marine dashboard applications, this speed gauge combines practical functionality with a clean instrument appearance. It is suitable for installation on recreational boats, fishing boats, cabin cruisers, center console boats, RIBs, workboats, utility vessels, and many other marine craft that use compatible speed measurement systems. Whether replacing an existing speedometer for boat dashboards or fitting instruments during a new installation, the MAZUZEE gauge provides a consistent analog display that complements standard marine instrument clusters. Its compatibility with both 12V and 24V systems also makes inventory management easier for boat builders, repair workshops, marine service providers, and vessel owners who work with different electrical configurations.

With its combination of an 85mm gauge size, dual MPH/km/h scale, two dial colour options, and integrated illumination, this marine speedometer is designed to offer straightforward operation and a professional appearance at the helm. It is a practical choice for marine maintenance, dashboard upgrades, replacement projects, and new vessel installations where an analog speed display is required.
