As stated before - use mid grade gas and you will be fine. On 2 stroke
engines you have no valves to worry about. However, you do have preignition
issues to worry about. The lead helped w/ this.
When leaded fuel went away - outboard manufacturers recommended you use at
least 90 octane fuel in the older engines or change the head gaskets to a
thicker gasket to reduce compression to prevent preignition.
Some will say use the cheap stuff but no more than you burn in a boat - the
10 cents a gallon is cheap insurance in my opinion.


Cool, will do.
