Maintaining and servicing your Honda

Keeping your outboard looking as good as the very first day you took it out on the water is not difficult at all – it’s just a matter of ticking boxes.

Servicing your Honda

As you’ll read in your Owner’s manual, regular servicing performed at the correct intervals helps make sure your Honda keeps on ticking along. Be sure to update your service record too, as this ensures you get the full benefit of your Honda warranty.

If you use your outboard engine in demanding or commercial conditions it may need more frequent servicing. Your dealer can tell you more about this.

Maintaining your Honda

Your Honda Marine Authorised Dealer is best placed to maintain and repair your machine on a regular, ongoing basis. We advise that any maintenance or repair be performed by the dealer you bought the equipment from, because they know it better than anyone else.

To make sure you get the best quality and reliability, we recommend you use only new Honda genuine parts.

Roll up your sleeves

There’s also a lot you can do as an owner to keep your equipment in optimum condition. Periodic maintenance will increase the life of your marine engine, giving you trouble-free boating for years to come. To keep it on top form, always check against the service and maintenance schedule in the manual.

Basic maintenance before use

  • Always check the oil level before you start.
  • When your engine starts, always take a moment to listen for any unusual sounds; and check that the water to cool the engine is flowing freely.
  • Take a moment to check that all bolts and fastenings are tight and the engine is secured to the boat.

Basic maintenance after use

  • Always allow the engine to cool before carrying out any maintenance yourself.
  • Always thoroughly rinse off, or flush out salt water with clean fresh water.
  • If you're storing the engine for a long time, disconnect the battery and drain any fuel that's left in the tank.
  • If your Honda is for commercial use, long hours of work may determine more frequent maintenance checks.

You’ll find full maintenance and service advice for outboard engines and inflatables in your Owner’s manual.
