Most two stroke engines in general run on a 50:1 ratio (Gasoline to oil). This means 0.5 liters of oil to 25 liters of fuel. Modern two strokes usually have an oil pump and inject the oil into the fuel at different rates according to rpm, however the pre-mixing of the fuel oil will still work fine in these engines. (However, you must disable the alarm for an empty tank if you do not use the automatic lube system on these engines) On Two Stroke Mercury engines pre-mixing is a good idea as the oil pump drives are prone to failure if the engine gets to hot!
The 1997 model, 40 hp Yamaha, requires a 50:1 ratio. This is roughly one pint of 2 cycle oil to six gallons of fuel.
The 1997 model, 6 hp Yamaha outboard, requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.

for every 9.2 litters of gas add 16 ml of 2 stroke premix oil wich is 32-1
How much doe a 1997 2 stroke johnson outboard motor weigh
The plug gap for a 9.9hp Mercury outboard, ( all models ), is .035 - .040in.
50:1 ratio
The fuel / oil ratio for the 1997 model, 25 hp. Mercury outboard, would be 50:1, this is roughly one pint of 2 cycle oil, to six gallons of fuel.
50 to 1
generally speaking if it has valves its a 4 stroke 4 cycle engine......if it doesnt have valves then it is a two stroke 2 cycle...................
No. 1997 Models 3Cylinder 25HP are 2stroke engines with a single carb.
