Checked my order, and it was a "Mercury Outboard Shop Manual 3.5-40hp
1972-1989 (Includes Electric Motors) I was suspicious of the shipping fee
of $3.99, as any book that covered that many motors would weigh about 16#.
So, it has to be just a short section on each motor. I cancelled my order.

Will get back to investigating this. It's just that I've seen OEM manuals
from $71 to $86! Maybe I can get a used one on ebay.

Advice? Clues?
