Mercury B721 Outboard Shop Manual 3.5-40 H.P., 1972-89 (Includes Electric Motors)

The book answers all of the questions that I had and will enable me to service my 40 year old Outboard more easily.The next day delivery was, as usual, awesome.

Well... the book was useful I guess, although you can get the same diagrams free online. I have a 1984 Mercury 3.5hp and didn't find the book as comprehensive as I would have liked.

I have a lot of experiences from manuals, Clymer, Haynes and others, for cars, motorcykles, outboards and inboards. This one is bad in some cases and fair in some. I still don't know how to exchange impeller on my 9,8 Hp 2 stroke Merc from 1972. I will therefore buy a book from Seloc and see if that one is better. If not, I'll use more force to take apart.My impeller looks different to them in the book.On my Honda Goldwing I used both Clymer and Haynes, and that was better than using one of them.

I have ordered Clymer Manual’s before for another motor brand . The brand is a great go to especially for older 2 cycle motors in need of schematics, parts numbers & in-depth list of all your motor needs to diyer’s & professionals as well. A great go to book . I especially liked the option to order one used at a great value in very good condition. You can’t go wrong with Clymer Brand Books . I would recommend these to anyone which I have before . Great help & Great value to have on hand for working in any outboard motor that’s compatible with multiple years & models .

Factory service manual. Does what was expected.

j'ai choisis la note là. cars je ne l'ai trouver nul par que sur amazon.frla revue et bien détaillée et ma beaucoup aidé pour la réparation de mon moteur.

Informative with pics, I do wish there would have been a water/coolant flowcharr, but overall, great producr!

It’s definitely not as detailed as a Merc shop manual but it gets the job done.
