How to Tune an Outboard Motor: Part Four

If you only tune your motor once a year, you should replace the fuel filter each time to ensure optimal performance. The filter is usually at the motor cover end of the fuel pump; the location of the filter can be found in your owner’s manual. When replacing the filter, clean out any water or sediment that may have accumulated in the area.

Next, replace the engine’s cowling and apply a coat of car wax to prevent rusting and corrosion. Now mix some fuel for the motor, combining the proportions of fuel and Evinrude XD100 oil that are specified in your owner’s manual. Once the motor is mounted, start up the engine and check for water flowing from the rear of the engine; this is an indication that the water pump is working. Let the engine warm up, and then adjust the low-speed carburetor jet and take you craft out for a test run. Performing this routine maintenance will keep your boat running smoothly and save you money on costly repairs in the future.
