Nonsense Inquiry

[Sea Rider]

Was wondering, how much time can hold any 2 strokes outboard run with 50:1 mix ratio at full throttle before engine head cracks, explodes, whatever might happen ? For full throttle operation you are supposed to use a richer oil mix ratio. Any ideas ?

Luis,

That answer would depend on the quality of oil used and the operating conditions (temperature, etc.).

50:1 is the richer mix ratio. The motor only needs 100:1 or less for low speed.

any 2 stroke covers a lot of territory.
