Seloc Publishing

Trusted Marine Repair Information Since 1974

Seloc Publishing has been the leading source of how-to information for the marine industry since 1974, establishing itself as one of the most respected names in marine repair documentation. Founded by Clarence Coles as an alternative to complicated factory manuals and lower quality aftermarket manuals, Seloc revolutionized the marine repair manual industry by creating accessible, comprehensive guides designed specifically for boat owners and mechanics who demand accuracy without unnecessary complexity.

Built on Actual Teardowns and Real-World Experience

What sets Seloc apart in the marine publishing world is their commitment to authenticity and practical application. Seloc manuals are based on actual teardowns performed by their editors, ensuring that every procedure, specification, and troubleshooting tip reflects real-world conditions. Authored by marine editors at Seloc's headquarters in West Chester, PA, these manuals start with official factory service, repair, and training information, then editors create condensed authoritative repair information aimed at the do-it-yourself owner.

In addition to step-by-step removal and installation procedures, Seloc performs and photographically records actual engine teardowns which provide the user with a strong visual sense of the actual repair. This hands-on approach means that whether you're tackling routine maintenance or a complete engine overhaul, you're guided by documentation that's been proven in real shop conditions.

Comprehensive Coverage for Marine Engines

Seloc offers a full line of printed manuals with complete coverage on everything, from basic maintenance to complete outboard motor and stern drive overhaul; featuring simple-to-follow, step-by-step, illustrated procedures, hundreds of exploded views, photographs, tables, wiring diagrams, and specifications. These manuals serve the needs of the professional mechanic, do-it-yourself boat enthusiast, technical school instructors and students, making them versatile references for anyone working on marine powerplants.

Empowering DIY Boat Owners

Since over 60% of the maintenance and repair operations can be performed by the average do-it-yourselfer, and with marine engines costing as much as a small car, the ability to do so many of those repairs yourself translates into thousands of dollars in savings over the life of your engine. Seloc's documentation philosophy recognizes that boat owners are often capable technicians who simply need clear, accurate information to maintain and repair their vessels confidently.

The company has continually evolved to meet changing needs in the marine industry, offering both traditional printed manuals and modern online subscription formats, ensuring that repair information is accessible whether you're in the workshop or at the dock.
