Ahoy there, I have a 50HP 93/94 Model Merc Outboard and to me it seems a little smokey, the motor starts first touch, has plenty of power and revs out just like it should, doesnt overheat so to me the engine seems fine, it was last serviced about 20 hours ago.<br /><br />At idle i notice a bit of 2 stroke smoke coming from it, mainly when its started im wondering if this is normal or not?. I have drained the fuel completely and measured a perfect 50:1 mix with Genuine Quicksilver oil and it was still smokey when I ran it on the weekend. Any ideas? is 50:1 definately the correct oil fuel mix?, anything I can do if its not normal?.<br /><br />Oh and also when I stop the motor and anchor somewhere I can see fuel/oil sitting on top of the water around the engine.<br /><br />Im thinking its running a little rich, at idle the motor does kick a little rather than idling perfectly smooth but im told all mercs do this anyway?<br /><br />Cheers Guys.
