2-37GBEMU01277Fuel EconomyThis meter displays the distance per liter orgallon when cruising for reference use bythe operator.Repeatedly push and release the “mode”button until the indicator on the face of themeter points to “ECON.”NOTE:@If twin engines are installed on your boat,the meter will display only the total fueleconomy of both engines.@NOTE:@ Fuel consumption varies greatly with boatdesign, weight, propeller used, enginetrim angle, sea conditions (includingwind), and throttle position. Fuel con-sumption also varies slightly with the typeof water (salt, fresh, and contaminate lev-els), air temperature and humidity, cleanli-ness of the boat bottom, engine mountingheight, skill of the operator, and individualgasoline formulation (winter or summerfuel and amount of additives). The Yamaha digital speedometer and fuelmanagement meter calculates speed,miles traveled, and fuel economy by watermovement at the stern of the boat. Thisdistance can vary greatly from the actualdistance traveled because of water cur-rents, sea swells, and the condition of thewater speed sensor (partially plugged ordamaged). Individual engines may slightly vary intheir fuel consumption due to manufactur-ing variations. These variations can beeven greater if the engines are of differentyear models. In addition, variations in pro-pellers, even of the same basic dimen-sions of the same design, can also causea slight variation in fuel consumption.@
