Hi,<br />I purchased a new 40hp Classic 2 stroke Mercury on ebay and it did not come with a manual. Wondering if someone could give me the proper break-in procedure from their manual? I know I can buy a manual from Merc but thought I would try this first.<br />Thanks!

Get the manual. Alot of mechanics will not even look at an old motor. You should break motor in at 24 to 1 oil. Use a good quality 2 cycle marine oil. Also replace the lower unit oil and the impeller. If the lower unit oil is white or water comes out you will need to buy a lower unit seal kit. Do not start this motor without water muffs or in a test tank. If you post the model and serial number someone will help point you in the right direction as to which manual and impeller to buy.
