Only 3.2 MB to download. If you sign in, you can start a library so you can quickly go back and see the interesting stuff. Try the advanced book search and have at it!! I have found most of the classic gas engine texts such as those by Dugald Clerk and Jones on this site. BTW- I am working on a couple of oil-fieldy engines now so have taken a break from the marine stuff for a while. I hope to get into a couple this summer.
