I have a 2006 Sea Ray 185 with a Mercruiser 4.3. The engine serial number is DW626893. It is the carbed 190HP version. I would like to purchase a service manual, but I'm not exactly sure what I'm looking for. Is there a part number or version number specifically for this engine/outdrive or do I just go by the year? Also, do you have suggestions on the best place to purchase a manual. Thanks for your help!
