I think I may have messed up. This is the book I ordered. Below it is the
90-# that was suggested to me to buy. Did I get the wrong book, or just not
the best book?

Book 1
Shipping estimate for these items: March 23, 2009 - March 26, 2009

1 "Mercury Outboard Shop Manual 3.5-40 Hp 1972-1989 (Includes
Electric Motors)"
Randy Stephens; Paperback; $29.16

Sold by: Amazon.com, LLC


Book 2
90-814676R1

The ad is somewhat ambiguous, stating this is the "Mercury Outboard
Shop Manual." I have seen those go for as much as $86, have a grey cover,
and look to be about three times as thick. The book from Amazon does fall
within the parameters for my engine serial number.

It's always something.
