  • Page 2 Protection and peace of mind WHY MAINTENANCE? Yamaha wants you to have an outstanding ownership experience. Maintenance plays a big part in that. We’ve learned a lot about caring for outboards during our many years as an outboard manufacturer; so here’s some knowledge and simple tips on the subject.

  • Page 4: Let's Get Started

    first things first LET’S GET STARTED We boaters can take a lesson from pilots, who perform a simple walkaround of their craft before each and every use. They know taking a few short minutes to do this every time is key to safety and enjoyment. Each time before you go boating, you should do the same.

  • Page 6: Corrosion Prevention

    DEFEND AGAINST THE ELEMENTS CORROSION PREVENTION While your Yamaha Marine dealer can help you with, or even do, most of your general and preventative maintenance, corrosion mitigation is something you can only do yourself—and time is of the essence. Regardless of where you boat, corrosion attacks both the inside and the outside of your outboard—every day, all the time.
  • Page 7 I boat exclusively in freshwater, do I still need to? Your Yamaha outboard is raw-water cooled, meaning it uses the water it’s operating on as cooling water. All water, fresh or salt, contains contaminants that will eventually build up in the cooling passages over time.
  • Page 8 If you’re unsure about what to do and when, your Scan here to see a video about corrosion prevention.* authorized Yamaha Marine dealer can help. Rinse it. • Don’t spare the hose when returning from a trip, particularly in saltwater. Rinse the entire outside of the outboard with clean water.

  • Page 10: Fuel & Fuel System

    Keeping your Machine clean FUEL & FUEL SYSTEM The largest source of trouble with marine engines these days lies with the fuel and fuel system. Paying regular attention to both can help prevent major headaches down the road. From hoses and connections to proper filtration and even fuel additives, time spent maintaining your fuel system helps keep you safe and your boat ready for action.
  • Page 11 It filters the gas and allows any water (which is heavier than gas) to safely sink to the bottom of the filter and out of the fuel. Yamaha’s spin-on 10-micron filter traps impurities down to 10 microns in size (1/20th of the diameter of a human hair), to keep your fuel clean, and has an extra-large water-retention area.
  • Page 12 Are there any other fuel filters, and where are they located? Your Yamaha outboard has a system of fuel filters on the engine, as well. It’s important to know the location of these filters and to clean or replace them at the recommended intervals. You can find this information in your service manual or through your authorized Yamaha Marine dealer.

  • Page 14: Electrical System

    TAKE CHARGE OF YOUR ELECTRICAL SYSTEM Today’s modern outboards and onboard electronics require juice to run. That’s why your electrical system is one of the most important systems on your boat. Because boats constantly operate on or are near water, electrical system care is even more important, especially in highly corrosive saltwater environments.
  • Page 15 Many large Yamaha outboards (150hp and up) have a separate battery isolator/charging leads specifically for charging these separate batteries. With proper wiring and components the charging system will be able to charge the starting battery/batteries first to help keep the voltage up and ready to go.
