The manual requires 33 parts petrol to 1 part oil.  20/1 for the first 10 hours.   The manual is in the section where the other manuals are listed.

I have been running 33:1 and find that it is too rich.  My mechanic said 50:1, I am going to split the difference and will let you know.

Fifty to one would sound good for most engines these days.. I've noticed that the guys with OMC saildrives have been discussing even lighter mixes when using synthetic oil.  I'd be careful with that, but it does make sense.
