Excellent manual!!!!
by Martin from Central Lake, Michigan on August 14, 2016
This is a excellent manual. Lots of figures and explainations. Only thing that I can say negatively is that if you are not real familiar with all the tools nessesary to complete a project. It might get frusterating. I have a beautiful 1970 searay SRV190 that I'm restoring. Nobody wanted to rebuild my OMC STRINGER outdrive. So I had to tackle it myself and now I know why nobody would mess with it. Parts are not terrible to find but its a time consuming endevour for sure. The book guided me through the rally though.!! Back to the tools bit, they should have a diagram of what will be needed to complete project for each section.

I have a 1969 120 omc that I would like to know how to remove the motor that raises and lowers the stern drive.?
This manual will help with how to do that.

Does this manual cover stern drive 990262S1 ?
Yes as you year is 1979 which this manual covers.

I have a OMC 3.0 L I/O. Does this manuel cover this engine.?
As long as your year range is between 1964-1986 on your OMC then yes this will cover your motor.

I have a OMC 200 engine in my 1980 Sun Runner, how can I tell if it is by GM?
OMC used GM engine blocks during their production years. By looking for a serial number that could confirm a reverse look up as well.
