I have read several post on octane use and would like to know what is recomended? The marina where i keep my boat only has 93oct. , but I can get 87oct. fairly easy. Are there any advantages of either? any comments?
93 provides no benefits (no more power, etc.), and probably more deposit buildup. but not to worry. If 87 is conveniently avaivable, use it, because that's all your motor (or almost any OB) needs.
