Hello people<br />My name is Luis, I´m from Panama, Rep. of Panama<br />I own a Bayliner Trophy with a single 5.7 Mercruiser with a Alpha one. It has salt water cooling system. Since a time ago, the gas consume have been increasing, it has problem to start and sometimes overheats at cruising speed with the boat at full load.<br />I changed, new sparks plugs and wires, new coil, did a maintenance to the distributor(sensor and rotor), new fuel pump, new impeller and thermostat, clean the elbows and raisers fron rust deposits. It is with good timming (8°)<br />Please advise
