Here is an article (1980 Outboard preveiw) from 1979 that has some information on the Water Pressure Power Steering. In the same Magazine there is part four of a feature called "18-footer around the continent" It is about a SSV-188 that they take to various places and boat, I know I have seen the time they were on the St. Croix......I will have to see if I can find all the parts (different months) and post. I am sure I have a service Manuel for the Cosworth 300 as well. Gregg, I also have an idea to make sure your CV will beat David...........
