Re: Repair manual
As already stated, you won't find a repair manual for the boat per se. What is out there that I would highly recommend getting are well written and detailed books about servicing/maintaining.repairing the various systems on a boat, as well as using a boat, other thing boat related. I'm listing 3 that I feel are essential for any boat owner that like to DIY. I own all 3, and find them to be invaluable resources.
If this is your first boat, you'll want the Bible of all things boating - "Chapman Piloting & Seamanship" - current edition is 66th, but you can pick up used 65th or even 64th and not be too far behind. Not much changes IMO.
"Boatowner's Mechanical and Electrical Manual" is an excellent resource for the basics of the most important systems, but is not enigine specific.
"The 12-Volt Bible for Boats" - truly the Bible of electrical methods, is easy for the layman, and considered the best in electrical.
In addition to those, you should also get a service manual specific to your engine. I like the Seloc manuals, and I bought the book and the online subscription. With the online subscription, it's easier to find what I'm looking for, then I just print out the pages I need and I don't have to worry about getting the book all greasy or damaged.
Hope this helps. Good luck to you, and welcome to iboats!
