  • Fluid capacities
  • Fuel types
  • Replacement circuits

Often specific to models, owner’s workshop manual provides step-by-step instructions and are more technical. If you can get your hands on one from a marine shop (or a third-party vendor) use caution. These are often several books, or volumes (can also be formatted for CD/DVD). Owner’s workshop manuals will help avid sailors diagnose their outboards in several ways:

• Advanced motor repair, maintenance, and service features
• Step-by-step instructions
• Strip-down diagnostics by piece and part including
