Want to buy the best service manual(s) for my '89 Evinrude 150XP outboard motor. Hope to gain access to all the OMC part numbers, troubleshooting advice, and service information.
There is good information on the model numbers of the different Evinrude outboards 1930 to 1980 at: http://www.marineengine.com/manuals/evinrude/ which includes a link to "model number codes here" picture of what they mean for all modern outboards 1980 to 1998 with also 1999 and newer (be sure to click on it with your mouse to blow it up so you can read it as will be too small to see when it opens) ...
