Seloc Service Manual - OMC Cobra Sterndrive Repair Manual, 1986-1998 (Part 118-03404)

This Seloc Service Manual is a complete, step-by-step repair guide for OMC Cobra, King Cobra, and Cobra "SX" stern drive units built 1986-1998, powered by Ford and GM 4-cylinder, V6, and V8 engines, including both carbureted and fuel-injected versions. Written for professional mechanics as well as do-it-yourself boat owners, instructors, and students, the manual is based on actual teardowns performed by Seloc's own editors and authors rather than reprinted factory text alone.

Inside you will find simple-to-follow illustrated procedures, hundreds of exploded-view drawings, photos, and reference tables, along with dedicated troubleshooting, specifications, and wiring diagram sections covering the full engine and drive system. Each repair procedure carries one of Seloc's exclusive Skill Level Ratings (1 to 4 wrenches) so you know the difficulty before you start, and Special Tool icons flag any step that requires an OEM or electronic testing tool. Seloc has been a leading source of marine how-to information since 1974, and this title is part of a line of over 40 manuals covering outboard, inboard, stern drive, and diesel engines as well as personal watercraft.
