What Do I Need to Install a New Prop on my Inboard Boat

When upgrading to a new prop or replacing an existing damaged prop, one of the common questions that is asked is "what do I need to install my new prop?". The answer to that questions really has two parts.

Part 1: Removing Your Existing Prop

The first step in the process, if you have not already done so, is to remove the prop that is currently on your boat. To do that, you will need a specialty tool called a prop puller that removes the propeller from the tapered shaft it sits on. Think of this tool as the jack you use to change a spare tire on your car; without it, you won't get very far if you have a flat tire.

There are two versions of prop pullers available, the harmonic puller, and the c-clamp puller.

Additionally, you will also want either a standard adjustable wrench, or our composite propeller nut wrench.

Part 2: Installing the New Prop

Once you have your current prop off, installing the new prop is very straight forward, and only requires the wrench used above to securely tighten the nut that retains the prop on the shaft. We suggest replacing the inboard propeller hardware kit that retains the prop every three times a prop is removed, since it's cheap insurance against losing a prop in the water (it happens all the time).

We also offer replacement cotter pins, and many other inboard boat propeller accessories.

Conclusion

With the right tools, installing a new prop on your inboard boat is a simple and straightforward project for any DIYer.
