Which octane should I burn?

I have a 97 150 fast strike and have heard a hundred different theories on octane so which should we be using?

87 octane is fine.Some opt for 89 for better additive package.<br /><br />Relatively speaking,a two stroke outboard is not a high compression engine and runs just fine on 87 octane.
