How to Match a Boat Propeller to an Engine
Choosing a new boat propeller can be confusing at times because there are so many different types. Not all of these are suitable for every boat so how can you make sure that you're choosing the right propeller?
Look in Your Handbook
Certain propellers are only suitable for very specific boats, which is why you should look in your boat's handbook to find out which propellers are suitable. If you need to replace your propeller, search on the Internet to try and find out which propellers will work properly with your boat.
Matching the Propeller to Your Engine
To match the propeller to your engine you will need to consider the pitch and the diameter of the shaft. If you choose the wrong propeller, it can cause the engine to vibrate, which could in turn cause parts to loosen.
It's important to choose the optimal propeller which will work the best in the situations you are using it in. If you are intending to use it in fresh water only, an aluminum propeller will be suitable. If, however, you want to use the boat in salt water, too, a stainless steel propeller is essential.
