Dt40 Suzuki Outboard Motor Manual

Posted on  by 



A Suzuki outboard service manual is a book of repair instructions and procedures for the maintenance, service and overhaul of a boat motor’s main components. A outboard service manual is often referred to as a repair manual, workshop manual or factory service manual.

Up until recently, these manuals were only available for purchase at book stores, and they were typically very expensive. Recently, however, these same manuals can be instantly downloaded from the Internet at a fraction of the cost. And the repair information in the manual is the same information dealer technicians use to fix your boat engine.

The difference between a factory service manual and a repair manual is small. A factory service manual doesn’t contain general knowledge. Therefore it’s important that the mechanic have some basic knowledge in marine mechanics or general mechanical repair. A repair manual is a manual that teaches the basics and fundamentals of marine mechanics in greater detail.
Both types of manuals cover every aspect of repair. It covers everything from basic maintenance, troubleshooting and engine overhaul. Pictures and diagrams are also included to help the mechanic successfully complete the repair job based on the factory specifications.
A downloadable repair manual is usually in portable document format (PDF). This type of file format is iPhone, tablet and computer friendly. There is no special software needed to download, open and view a PDF repair manual. That’s because virtually every electronic device designed for this purpose is factory installed with the software needed to download, open and view a PDF.
A downloadable service manual is identical to a repair book you’d buy in a store. It contains a cover page, table of contents, index page, and complete step-by-step repair procedures. Here is a list of main chapters often found in an outboard repair manual:
  1. Cover page
  2. Table of contents
  3. General information
  4. Troubleshooting
  5. Periodic maintenance
  6. Engine control system
  7. Electrical
  8. Fuel system
  9. Mid unit
  10. Lower unit
  11. Powerhead
  12. Power trim and tilt (if equipped)
  13. Wire and hose routing

As with any repair manual, complete part inspection, testing, removal, disassembly, assembly and installation procedures are included. As well as other important information, such as engine specifications and torque specs.
Probably the most important aspect of a repair manual is the troubleshooting guide. Troubleshooting is the activity of tracing and correcting malfunctions in the boat motor’s electrical or mechanical system. It’s a systematic approach to locating the root cause of the problem and fixing it.
