Re: gas and oil ratio
Doesn't have to be xxxxx-3 but that's what's on the street today and is better than it's predecessors. My Merc manual published in 1997 says xxxxx-2, but that was the best then. Back in 1966 the industry was just getting over using automotive non-detergent oil for 2 cycle lube....so as the sayin goes....we've come a long way baby. Ha.
