Step-by-Step Procedure to Remove Volvo Penta Duo Prop
- Prepare the Boat: Secure the boat in a stable position. Make sure the engine is off and cool.
- Remove the Propeller Nut: Use the socket wrench to carefully unscrew the propeller nut. This may require some force if it’s been in place for a while.
- Apply Penetrating Oil (if necessary): If the nut is stuck, apply penetrating oil and allow it to sit for a few minutes to loosen it.
- Detach the Propeller: Gently pull the propeller straight off the drive shaft. If it’s resistant, utilize the propeller puller for a smoother removal.
- Inspect the Components: Check the propeller and the drive shaft for any signs of wear or damage. Replace any faulty parts before reinstallation.
- Clean the Area: Clean any debris or old grease from the drive shaft and the area around it.
- Secure the Components: Store the removed propeller in a safe place to prevent damage until it is ready for reinstallation.
