How To Change a Boat Propeller Instructions R&R Propeller

To remove and replace (R&R) a boat propeller, you will need to follow these steps:

1. Preparation: Before you start, make sure that you have the right tools for the job. You will need a set of wrenches or sockets that are compatible with the mounting bolts on your propeller, as well as a hammer and chisel or a propeller puller if the propeller is stuck.
   
2. Drain the lower unit: If your boat has an outboard motor, you will need to drain the lower unit before removing the propeller. This can typically be done by removing the drain plug on the side of the lower unit.
   
3. Loosen the mounting bolts: Locate the mounting bolts that hold the propeller in place. These are typically located near the center of the propeller and will be tightened onto the drive shaft of the boat's engine. Using the appropriate wrenches or sockets, loosen the mounting bolts but do not remove them completely.
   
4. Tap the propeller gently: If the propeller is stuck, you may need to gently tap it with a hammer to loosen it from the drive shaft. Place the chisel or flat edge of the hammer against the back of the propeller and give it a light tap to loosen it.
   
5. Pull the propeller off: Once the mounting bolts are loosened and the propeller is no longer stuck, you should be able to gently pull the propeller off of the drive shaft. If the propeller is still stuck, you may need to use a propeller puller to gently pry it off.
   
6. Remove the mounting bolts: Once the propeller is off, you can remove the mounting bolts completely. Store them in a safe place, as you will need them to reinstall the new propeller later.
   
7. Clean the propeller: Before you put the old propeller away, take a moment to clean it. Use a soft cloth and a mild detergent to wipe away any dirt or debris that may have accumulated on the propeller. This will help to prevent corrosion and ensure that the propeller is in good condition for future use or disposal.
   
8. Install the new propeller: Once the old propeller has been removed, you can begin the process of installing the new propeller. Carefully lift the new propeller onto the drive shaft and line it up with the mounting bolts. Then, using the appropriate wrenches or sockets, tighten the mounting bolts to secure the propeller in place.
   
9. Test the propeller: Before using the boat again, it is important to test the new propeller to ensure that it is functioning properly. Slowly rev the engine and watch the propeller to ensure that it is turning smoothly and without any noticeable vibrations. If everything appears to be functioning properly, you can resume using the boat as normal.
