Yamaha 55AE connecting rod bolt torque

[Nunes]

Hi, I'm new over here, first of all I would like to say hello

I'm rebuilding an old 55hp and I'm having trouble to found the correct torque for the connecting rod bolts... a friend told me to use 1.5kgfm, but I'm not sure if this value is correct. Anyone can help me with this ?

Besides, as I don't have a workshop manual, I also don't know the correct torque for the cylinder head bolts.

About the manual, I live in Brazil, and is not that easy found this thing over here.

Thanks
