Removing the Old Prop

Before you can replace a boat prop, you need to remove the previous one. In order to accomplish this task, you must use one of the tools in your toolbox to remove the large nut and cotter pin that is contained at the very end of your prop shaft.

Removing the Washer

The next step in the boat prop replacement process involves taking out the washer. The washer will not require any tools to remove. You should be able to take it out by using your hands. You can even get your kids to help you, and make it a family project. At this stage of the procedure, it is time to place the new boat propeller that you have purchased on the lower unit. Once it is situated in the correct position, make sure this new piece of equipment is lined up accordingly. The spine on the prop should be aligned with the spines that are contained on the prop shaft. If it slides directly on without any effort, you have placed it on in the correct manner.

Final Step

The final step in the process is simply a matter of replacing the items that you have removed. The washer must be returned to its previous position, and adjusted so that it is not too loose. This will ensure that your new propeller will not fall out of position. Also, replace the nut; make sure that it is not overly tightened. Nuts that are too tight can destroy your boating props. The last thing you want to remember to do is replace your cotter pin. Your lovely boat is now back in business for the entire world to view. Since you now know how to replace a boat prop on your own, you can charge your boating friends a small fee to do replace their boat props, or even do it for free just because they are your friends. As you can see, if you can use your hands, follow a few simple directions, and set aside some time to do the actual work, it is not a hard process to do it yourself.
