Digital Fuel Management Gauge Notes on Fuel Consumption: ta Fuel consumption will vary greatly with boat design, weight, propeller used, engine trim angle, sea conditions (including wind), and throttle position. Fuel consumption will also vary slightly with the type of water (salt, fresh, and contaminate levels), air tempera- ture and humidity, cleanliness of the boat bot- tom, engine mounting height, skill of the operator, and mdividual gasoline formulation (winter or summer fuel and amount of addi- tives). The Yamaha Digital Speedometer and Fuel Management Meter calculates speed, miles traveled, and fuel economy by water move- ment at the stern of the boat. This distance can vary greatly from the actual distance trav- eled because of water currents, sea swells, and the condition of the water speed sensor (partially plugged or damaged). Individual engines mav vary slichtly in their fuel consumption because of manu- facturing variations. These variations can be even greater if the engines are of differ- ent vear models. In addition, variations in propellers, even of the same basic dimen- sions of the same design, can cause a slight variation in fuel consumption. Fuel Management Gauge Operation Instructions The Yamaha Fuel Management Gauge System consists of a fuel flow meter, fuel consumption meter, fuel economy meter, twin engine speed synchronizer for dual installations, and an option- al water separator warning indicator that detects water in the fuel filter. 1, FUEL FLOW METER 7 FUEL CONSUMPTION; FUEL ECONOMY METERS TWIN-ENGINE SPEED SYNCHRONIZER 3%.

If the amount of fuel consumed differs from that indicated on the meter, it can be calibrat- ed to the correct amount. If the amount of fuel used differs from what 15 indicated on the meter, calibrate 1t to the correct amount by: 1. Fill the tank and operate the boat. Use about 75% of the fuel in the tank. 2. Refill the tank and record the amount used. 3. Compare the actual amount of fuel used with the gauge reading. 4. If there 1s a difference, use the formula below to figure the difference as a percentage. Refer to the illustration and adjust the switches to calibrate the gauges. Example: Actual Amount of Fuel Used: 50 gallons Fuel Management Gauge Indicates 51 gallons Difference = +1 gallon 1.0 gallon / 50 gallons = 0.02 or 2% Therefore, 1 gallon 1s 2% of the actual 50 gallons used. To calibrate the gauge, set the switches for - -2% (because the gauge was showing more fuel than was actually used). If the gauge was showing less fuel than was used, the switches would then be set for a + percentage.
