Veratron 3-3/8" (85MM) ViewLine Synchronizer -500/+500 RPM - 8 to 32V - White Dial & Bezel

The Veratron 3-3/8" (85MM) ViewLine Synchronizer -500/+500 RPM is purpose-built for twin-engine boat installations where keeping both motors in perfect rhythm is essential for fuel efficiency, handling, and overall vessel performance. On the water, even slight RPM imbalances between paired engines create steering torque, increase fuel consumption, and put unnecessary strain on your drivetrain—problems this synchronizer eliminates. Whether you're running a center console, express cruiser, or larger sportfish platform, this marine-grade instrument provides real-time RPM matching that lets you focus on navigation and fishing rather than constant throttle adjustment.

The ViewLine synchronizer monitors engine RPM across a -500 to +500 RPM range, displaying differential speed on its clean white dial and bezel in easy-to-read increments—critical for catching imbalances before they become problems. Operating on 8 to 32V DC power, this unit integrates seamlessly with modern and legacy marine electrical systems alike, and the 3-3/8" (85MM) display fits standard marine instrument panels without modification. The synchronizer's robust construction and sealed housing withstand the vibration, salt spray, and thermal cycling inherent to marine environments, ensuring years of reliable service in demanding conditions.

Ideal for professional captains, charter operators, and serious recreational boaters with twin-engine vessels, this Veratron instrument pays for itself through improved fuel economy and reduced maintenance costs. Installation requires connection to both engine tachometer outputs and your vessel's main power bus—a straightforward setup for any qualified marine electrician. The compact 0.75 lb weight and modest 7 x 3 x 8 in footprint make it easy to integrate into existing helm layouts, whether you're upgrading legacy instrumentation or building a new control system.
