yamaha maintenance schedule
How often should you service your Yamaha outboard? Our Yamaha Outboard Maintenance Schedule outlines replacement and inspection activity based on “typical” use. Typical use is defined as:
- Operating your Yamaha outboard at various speeds
- Typical cruising speed near 3000 to 4000 rpm range
- Allowing sufficient time for the engine warm-up and cool down
Suppose you frequently utilize your Yamaha outboard in a more demanding manner than typical use, such as long periods of wide-open throttle or extended periods of trolling. In that case, your service intervals should be shorter. All Yamaha outboard parts required for each service interval are available at PartsVu.

Yamaha 4-Stroke Oil Change— 100-Hour Service
Performing needed maintenance in a timely manner on your Yamaha outboard is the key to its overall longevity and reliability. This article provides a step-by-step guide for Yamaha 4-stroke oil change, the first step in 100-hour service.
Yamaha Spark Plugs & Compression— 100-Hour Service
Performing Yamaha spark plugs and compression maintenance on your outboard is one of the keys to its overall longevity and reliability.
Begin this step of your Yamaha 100-hour service by removing the plastic shrouding over your spark plugs or ignition coils. Yamaha engines come from the factory with NGK brand spark plugs, and PartsVu carries a wide assortment of these OEM plugs. In most applications, the spark plugs come pre-gapped, but it is advisable to re-check gap to make sure that no plugs were damaged during manufacturing or shipment.
Yamaha Fuel System— 100-Hour Service
Yamaha fuel system maintenance is a critical aspect of 100-hour service. Depending on your application and style of boat, you likely have a fuel-water separating filter aboard your vessel. If you have not seen one, simply follow the routing of your fuel hose from the engine rigging tube backward through the boat. These vary in shape and manufacturer, so be sure to order the identical replacement filter. Use a filter wrench to loosen the existing filter element and use caution when removing it as it will be filled with gasoline.
Yamaha Lower Unit— 100-Hour Service
Yamaha lower unit gear lube is drained by removing the lower drain screw first and then the upper plug vent to allow air in. On most models, both plugs are clearly visible on the lower unit, but on models with low water pickups, the forward pickup will need to be removed to access the drain plug.
Yamaha Grease Points— 100-Hour Service
Paying the proper attention to Yamaha grease points is the final 100-hour service step. It is advisable to grease your engines’ grease fittings more frequently than your 100-hour or annual service, but if you haven’t, now is certainly the time.
