Can anyone point me in the right direction to find a diagram for the vacuum/drainage lines for this OB? I have a svc manual I down loaded from http://folk.uio.no/froder/stuff/50GETO_6H2_28197_Z9_11.pdf but this is from a European site & not totally correct nor inclusive of minor system diagrams AND doesn't even show the port in my PH has.. Also, the 'Yamaha' site owners / service manuals are of no help w/ this. There is a port, approx.,1/8 in size, just under the flywheel on the starboard side of the PH that I thought was a drainage line, but that proved incorrect as there is a vacuum when the motor was running. As I didn't disassemble this motor (pics would've been taken), I do not know where this line terminates. There are other lines of that side of the PH, but they are all correct. I'm at a loss here.
As internet searches are overly laborious, any help anyone can offer will help.
Tks in advance.
