Back on the oil...I wouldn't use the outboard oil if I were you. If you look on the container it will say "TCW" which stands for two cycle water cooled. The oil for water cooled engines is different than the oil for air cooled engines because the water cooled outboards run cooler than our air cooled engines. You should be using oil that says "TC". Any of the oils designed for air cooled motor cycles or weedeaters and such should be fine.
