I am a jetboat owner/enthusiast with too much time on my hands. So I used up some of that evil time by making a technical handbook as my "gift" to all of us. I expect the handbook to run 3 maybe 4 volumes. Volume 1 is ready and runs about 17 pages and has a file size of almost 1Mb because of charts and pictures and such.
