Faria Beede 4 Inch Dual Engine Synchronizer Gauge

The Faria Beede 4-Inch Dual Engine Synchronizer Gauge solves a specific problem on twin-engine boats: matching RPM between two engines by feel alone is imprecise, and running them out of sync wastes fuel and adds vibration you can feel through the whole hull. This gauge displays both engines' RPM difference directly, letting you dial them into a genuine match with a quick throttle adjustment rather than guessing by ear.

It's built to work across gas and diesel dual-engine setups, with a perimeter-lit dial that stays readable day or night, and readings marked in both standard and metric units with icon labeling so the display is easy to interpret at a glance.
