Save money, install a Fuel Flow Gauge on your Boat!


Itís tough to gauge the most efficient cruising speed without a fuel flow boat gauge.

There are mechanical fuel consumption measuring devices from companies such as Lowrance and Floscan.

Digital boat instruments such as the SmartCraft MercMonitor or VesselView can also read fuel flow from the boatmotorís electrical brain by using just one cable that is attached from your Mercury Outboard to the NMEA 2000 network.


Which one's right for your Boat/Motor combination?
