After acquiring my new old boat, a nice little Bertram Caribbean from 1973... (with a solid floor) I also scored a 1973 Johnson 3cylinder 70Hp motor, in pretty sweet condition. Following the multiple posts about motors and servicing.... I bought a manual online covering years from 1973 to 1991, 3cylinders, V4s and V6s, 60HP to 235HP.

Although it seems an old copy, there is a ton of info in it, if others have a motor that they need a manual for, you can get the copy here:

There are no blind links or requests for money, I hope people get good use of it, especially if it saves a good engine from the scrap yard..

Cheers.
