Back in the day we mixed all our outboards at 1 quart oil to a 5 gallon tank. Imperial gallons here in Canada .We had 5hp 5.5hp 10hp and 25hp all from the fifies.I still have the tn27 5hp it was the first new motor my dad bought in 1951.Most of these engines had thousands of hours on them.I believe most of the engine failures on the 5.5 and 7.5 were because there was no throttle stop in neutral I have heard many started at full blast and over rev while the inexperienced operator is trying to figure out what step is next.
