Do you know when you're burning too much fuel? Our guess is that like most of us, you can't tell whether you're conserving fuel or going through your tank like crazy just by tracking your boating habits. If you want the true peace of mind that comes with knowing how much fuel you've used and how much you're using, you need a marine fuel flow meter. Used properly, a marine fuel flow meter can even pay for itself! Please note: Many marine fuel flow meter systems are designed specifically for gasoline or diesel engines. If you're unsure what kind of marine fuel flow meter you need, contact us to talk to one of our customer service reps. And remember, we guarantee free shipping on all our discount marine instruments and marine equipment to the lower 48 states* and offer unbeatable flat rate shipping upgrades to get you your merchandise faster!
