How Do I Know If My Boat Propeller Needs to Be Replaced?

There is a lot of equipment and maintenance you’ll need to do on your yacht or powerboat over time, but one thing a lot of people seem to forget is their boat propeller. The propeller is one of the single most important things you will need to keep an eye on to ensure that you can make it back from your boat trip.

Today, we will be sharing 6 common signs that your boat propeller may be on the verge of dying so that you know when your boat propeller needs to be replaced.

6 Signs You Need a New Boat Propeller

These are just a few of the more common signs you should always be on the lookout for:

1. It Has Too Much Pitch

When you are doing your research on what size propeller to choose, you’ll see that there are always two numbers on each one. For instance, the first number will always mean its diameter, while the second number will always refer to its pitch.

When boating, the pitch will refer to the distance your propeller will move throughout the water in one complete revolution. For example, let’s say your propeller has an 18-inch pitch. What this means is that your propeller should rotate once every 18 inches.

Why does this all matter? Well, when your boat has too much pitch, it starts to get difficult for the boat to accelerate, which will leave your boat overly sluggish.

2. Not Enough Pitch

This will tie in with the first reason that your boat propeller is ready to be replaced. If you do not have enough pitch, it could mean that you will need a new one as well. If you leave your boat propeller without enough pitch, you will end up causing more damage, which in return will cost you more money than a new propellor.

Please note: Sometimes, when your propeller is not getting enough pitch, it doesn’t mean you will need to replace it. There are times that a simple adjustment will do the trick.

3. Decreased Fuel Efficiency

One of the more blatant signs that your boat propeller will need to get replaced very soon is that you will be spending much more money on petrol.

A lot of people do not know that your gas usage is tied in with your boat propeller. It is very similar to how you will spend more money on fuel if you have inadequate tires on your car.

If you notice that you are filling up your tank more often, you may want to get that propeller change.

4. Incorrect Diameter

When you get a propeller, you want to make sure that you are selecting the correct diameter size. If you get one that is not the right size, you will find out that it will not fit your boat correctly.

You must always check the diameter size before you purchase the propeller. You will need to understand the diameter and pitch sizes when it comes to your boat.

5. Damaged in the Water

You love to hit the water. You spend your days on the water, but what you may not always think about during your fun time is that your propeller has the chance to come in contact with things lurking in the water such as, sandbars, rocks, and other debris.

Of course, this doesn’t mean you will permanently damage your propeller, but you should always check your propeller before and after you are done with your boating trips. This will allow you to see if your propeller is dinged, chipped, or bent in any way and can let you get a new one before your next boating day.

6. If Your Propeller Is Made of Aluminum

Suppose you are not an avid boater, then this really will not be of value to you. However, if you’re in your boat every weekend, you know getting an aluminum propeller is not a good choice. You will want to get a stainless steel propeller because stainless steel propellers are much more durable and can take a bit of a beating, as well as avoid corrosion, unlike aluminum propellers.
