Performance & Practical Benefits

This tach keeps your setup looking sharp while giving you the accuracy you need. The 7000 RPM range is ideal for high-output outboards and performance setups that need tighter RPM tracking. SmartTow adds a layer of control for consistent acceleration, while v9.0 and newer systems expand what the gauge can show — including trim and oil-level status. It’s a solid, dependable piece that works as good as it looks.
