older evinrude fuel mixture

[jack bowman]

I just bought an older evinrude -model # 335528-a 33 hp ski-twin<br /><br />What is the appropriate oil fuel ratio. My marina suggested 24:1 but my buddy says it will run better with a leaner 35 or 40:1 <br /><br />Help

Thanks papasage . <br /><br />50:1 is quite a bit leaner than the local marina suggests. <br /><br />Is this the ratio called for in the operator's manual?
