The Seloc Service Manual 118-01408 is a complete repair and service reference for Mercury outboard engines built from 1965 to 1989, covering the 90-300 HP range across inline 6 and V6 2-stroke models, including fuel injected units, with information on Mr Drive as well. It is built for the do-it-yourself boat owner and the professional marine technician who need a single, comprehensive source for troubleshooting, repair, and maintenance work.

Inside, the manual uses simple-to-follow illustrated procedures supported by hundreds of drawings, exploded views, photos, and tables, so each repair step is easy to visualize before you start turning wrenches. Troubleshooting charts, specifications, and wiring diagrams are included to help diagnose issues quickly and confirm parts are reassembled to the correct settings. A distinguishing feature of Seloc manuals is the Skill Level Rating system, which grades each procedure from 1 to 4 wrenches based on its difficulty, along with Special Tool icons that flag steps requiring an OEM or electronic testing tool.

This title is one of more than 40 Seloc manuals covering outboard, inboard, stern drive, and diesel engines, as well as personal watercraft, giving owners of Mercury outboards in this coverage range a dedicated, engine-specific reference rather than a generic guide.
