For inboard boat motors we carry Seloc tune-up and repair manuals written for OMC, Mercruiser and Yanmar. The manuals' cover repair and service on all major engine components, including fuel system diagnosis, cooling systems, regular maintenance, electrical and charging systems, transmissions, overhauls, steering and much more. While the inboard manufacturer list is short, the models covered within each manual are not, providing a wide range of Mercrusiers, Yanmar and OMC model coverage. At iboats we ship your repair manual fast so you can have confidence in doing the repairs yourself and saving money. If you have a question about model or component coverage, give us a call, one of our knowledgeable customer service agents will be glad to assist you.
