My girls who wakeboard consensous on 2 cycle oils:
The Mercury Blend 2 stroke oil: smoked and stunk very bad.
Kawasaki blend 2 stroke oil: less smoke and smelled better.
Yamaha (watercraft blend) 2 stroke oil: no smoke and the smell was more tollarable
Suzuki CCI 2 stroke oil:, No smoke, no odor at all.
I used a gallon of each brand, 3 gallons of the Merc. oil in our 2002 FI 250 Mercury outboard.
We take 3 three- 10 vacations and several extended weekends to Parker and seem to be towing constantly.
The Mercury oil was so obnoxious to my skiers, that it prompted me to try other oils.
We stuck with Suzuki CCI, and then our friends switched to it too and everyone concurred no smoke, no odor, clean plugs.
Just my 2 cents worth.
