I agree - you want the factory shop manual.

You might be able to get one online and download it to your computer (cheaper). I do prefer being able to leaf back and forth in a paper version, but you may be able to print the pages for what you want to do. With printouts, you won’t care if you get oil or grease on the pages and if you have an old laptop computer laying around, you can dedicate it to “shop computer” and have your manual handy. I did that for an old ford truck and it worked well.

I do have a Mercury manual for my engine but that does help me with some things but once they start talking about gaps and tourque and getting nin to measurements And stuff like that, I'm done. The problem is I don't like to take chances , I took my engine to a mechanic to bypass my oil injection system and I'm sure I could have done it and if I ran into a wall you guys would have walked me thru it. But I didn't. Like carbs, I don't know anything about carbs so to the shop it would go. I used to go to a good Mercury shop ( anglers marine) in seabright n.j but the owner passed away and his new wife took over and turned it into a beach chair and umbrella shop. Yep they are gone now so I really can't find a honest mechanic and with the price of gas I can't drive it to spareparts shop lol all we ask is for a good and honest mechanic but getting back to the Yamaha. That's going to be a huge issue. And to make matters worst the head was rebuilt 2 years ago so it's out of warranty and my son uses it a lot. Put a lot of hours on it. I don't know. We just have to see the next move.
