New 2003 Merc 40 hp sounds bad
I just bought a new 2-stroke 40 hp Merc (elct start)for my duck boat. From the first time I used it, it has the following problems:<br /><br />1) Starts hard - It will start very quickly but then dies, I usally have to attempt to start it 5-6 times before it stays running. Maybe I do not choke it enough?<br /><br />2) Runs rough at midthrottle when cold<br /><br />3) Sounds rough upon decelerating through the midthrottle range (hot or cold) like it is knocking.<br /><br />4) Motor is quiet at low idle and at full speed, however gets suddenly relativly loud at midspeed.<br /><br />any ideas, the motor is still doing all of the above. I now have about 4-6 hours on the motor, I still have some of the break in oil in the gas - but that is dilluted now as I have filled up recently.<br /><br />-C
