Sorry, missing the last page(s). This article has lots of info on many of the boat engines Keith Black built.
If you are on a desktop computer – the best way to view this book is to click the “toggle fullscreen” button, then use your arrow buttons on the keyboard to advance to the next covers. I scanned this at a larger format, so you can “enlarge the pages” to read by clicking the “zoom in” button. When you are done with reading the book, just press your “Esc” (escape) key and your monitor will go back to your normal view.
