How to fill out impeller shimming - outboard

How to fill out impeller shimming - outboard:

1. Start by removing the outboard motor cover to gain access to the impeller housing. Ensure that the engine is turned off and the spark plug is disconnected for safety.
2. Locate the impeller housing, which is typically located near the bottom of the motor. It may be covered by a plastic or metal plate that needs to be removed.
3. Use a wrench or screwdriver to remove the bolts securing the impeller housing cover. Carefully lift off the cover, taking note of the position of the impeller inside.
4. Inspect the impeller for any signs of wear or damage. If the impeller blades are worn down, chipped, or bent, it may be necessary to replace the impeller altogether.
5. If the impeller is in good condition, you can proceed with shimming. Shimming involves adding thin plates or shims to adjust the impeller height, ensuring optimal performance and water flow.
6. Obtain the appropriate shim kit for your outboard motor model. These shim kits typically include different thicknesses of shims to choose from.
7. Carefully place the selected shim on top of the impeller, ensuring it covers the entire surface area. Double-check that the shim is properly positioned and aligned with the impeller blades.
8. Replace the impeller housing cover and secure it with the bolts. Ensure that the cover is tightly sealed to prevent any water leaks during operation.
9. Reattach the outboard motor cover and reconnect the spark plug.
10. Start the outboard motor and observe its performance. Pay attention to any changes in water flow and temperature. If the engine runs smoothly and the water flow is adequate, then the impeller shimming process is successful.
