I've refit a Catalina 30, and now have a J-133 that we live aboard, cruise along the coast of California, and race, and this book is the bible for all things mechanical and electrical on a boat. I keep it on the boat at all times (in spite of how hefty it is!). Here's a link to it on Amazon. You NEED this book if you have a boat: https://amzn.to/4nDAyiX
