...and my advice would be if you're going to take it in, do it sooner than later. Some of these places end up with a 2 or 3 week waiting list during the warmer months and we're getting close to Memorial Day.
I have a 115 Merc. I never winterize it (what's the point if you go to Pueblo in the winter -which I've been swearing I'm going to do the past 3 years). This year I ran some injector cleaner through it and it's running great. A change of plugs will set you back about $7 each (based on the brand Mercury recommends) and is worth it at least once per year. Don't forget to change the oil at about twice per year. My neighbor's motor smokes much more than mine (I have a 2002) and can't offer any explanations there except I know that some places put a coating on the motor when winterizing it that will cause it to smoke. I would say shop around for a tune up. I think the place here on Federal in Littleton is about $150 for a tune up and Aurora Marine is even more.
