KUS Marine Analog RPM Gauge / Tachometer for Outboard Motors, 85 mm – Maximum Safety for Your Engine
Get the most out of your outboard motor and always operate within the optimal RPM range! The analog KUS outboard tachometer provides you with an extremely responsive, real-time display of engine RPM as well as an integrated digital LCD operating-hour counter. What sets it apart: This specialized instrument features 4 integrated LED warning lights for immediate visual indication of critical engine conditions—the ultimate control center for pleasure boats and inflatable boats.
With the standardmarine mounting diameter of 85 mm (3 3/8"), this round gauge fits universally into existing cutouts at your helm. The elegant bezel, made of high-purity, saltwater-resistant AISI 316 stainless steel (NIRO ring), ensures a timeless design and optimal protection in harsh marine environments.
⚙️ Universal connection for 2-stroke & 4-stroke outboard motors
This KUS instrument is compatible with nearly all common outboard motors (e.g., Mercury, Yamaha, Suzuki, Tohatsu, Honda). The RPM input signal is easily tapped from the ignition coil or the charging coil (alternator / terminal W).
Easy calibration: The RPM ratio can be continuously adjusted from 1.0 to 10.0 using a splash-proof rubber knob on the back of the housing. This allows you to precisely adjust the display to match the number of poles on your alternator in no time at all.
Advantages & Technical Highlights at a Glance:
- Integrated 4-color LED warning indicator: Immediate visual alert for critical conditions such as low oil pressure, engine overheating, low charging voltage/battery, or engine fault (Engine Check).
- Digital operating hour counter: The integrated LCD counter precisely records engine runtime up to 99,999.9 hours. All data remains permanently stored even after the main switch is turned off.
- 100% Waterproof (IP67): The entire front panel is certified as completely dust- and waterproof to IP67. The double-layered, reinforced, anti-fog glass prevents condensation from forming during rapid temperature changes in the cockpit.
- Dual System Voltage: Can be used directly in 12-volt and 24-volt vehicle electrical systems without additional ballast components.
- Switchable Backlighting: During installation, use the simple terminal configuration to flexibly choose between bright red or yellow dial illumination.
🛠️ Accessory tip from Tenten-Boats:
A tachometer is the heart of the helm station. For a perfectly cohesive cockpit design, we recommend pairing it with the matching KUS trim gauge (52 mm) to monitor engine trim or the practical KUS analog voltmeter/battery gauge from our product range.
