How Propellers Work

If I try to explain a propeller in the simplest way, I would compare it to a fan. The blades of a fan cut into the air, pushing it out the other side of the fan. A boat motor propeller works in the same way as a fan in theory.

The physics of water is a bit different than air, but simple mechanics are the same. Boat propellers have some unique design features that make them perform well in water converting the revolutions of the motor shart into thrust to move your boat.

We will talk more about propellers in general, such as a medium to a large outboard motor. Most of the medium size class of boat motors have three identical blades. Blades are measured in a few ways starting with pitch.

Blade pitch is the angle of the blade, and the number implies the non-slip distance a blade will travel in the water for one complete revolution. An example of this is a 17 pitch blade that will travel 17 inches forward for one complete revolution. Mercury 90 hp motors use 17’s as standard equipment.

Blade diameter is another key property of a propeller. The larger your blade diameter, the more water you will move, or aka disturb. However, if your blade is to larger, your motor will not reach full RPMs, so getting a perfect balance is important.

For more about Prop size, there is an excellent article on the Marine Parts Express website.

There are some other properties like the propeller cup or cupping. The cup is a curve from the middle to the trailing edge of your propeller. This cup feature gives the prop a better punch or hole shot, by reducing slippage and ventilation during acceleration.

Finally, Rake is the degree a blade slants in relation to the hub, theoretically in relation to the prop shaft. The best way I can explain the benefit of rake is holding on to the water so you can trim your boat up or down for a smoother or faster ride.

Propellers can be made out of many materials. Most gas motor propellers are made from aluminum because of cost and versatility. Most electric trolling motor propellers are made of plastics or composite materials.

The basics physics for a trolling motor propeller are the same as a more substantial motor however, top speed and plaining your boat are not considerations.  It is still nice to have a prop that will provide quick response and energy efficiency (of fuel efficiency for gas motors).

The most significant difference for trolling motor propellers is the diameter related to the horsepower by percentage. Trolling motor propellers are larger by percentage than a higher horsepower main motor.

How to Choose a Minn Kota Trolling Motor Propeller

When choosing a Minn Kota trolling motor propeller, it can help first to determine your primary fishing type. I like to break it down into two fishing types trolling and holding. Not that there are no other methods to utilize your trolling motor while fishing, but these are the two main categories.

When you are using your motor to troll, it is very straightforward. You set your motor to a preferred speed, deploy your gear, and make small adjustments as you go. Your main concern will be consistent speed and efficient power consumption.

Bass fishermen almost always fish in a holding pattern. Put your boat in a spot, then cast in a pattern, move and repeat. For fishing a pattern, a quick and accurate response is essential. Narrowing down what you need out of your motor can help you choose the best propeller.

How to Install a Propeller

Before you start this project, be prepared with a towel to clean any obstructions from the housing that may have entered through use. This is essential to ensure a well-functioning propeller. Disconnect the electric trolling motor from all battery terminals. The tools you need to install a Minn Kota trolling motor propeller are vice grips or nose pliers.

Start by cleaning the propeller and its surrounding area. This will also help loosen the bolts, so taking it apart would become easier.

Turn the locking nut counterclockwise to remove it. Once that is unscrewed, remove the lock washer. It is located directly under the locking nut.

If you have purchased a new Minn Kota trolling motor propeller kit, replace the lock washer with the new one that came with the kit.

Push the drive pin on either side to make it slide out. When installing the new propeller, make sure the drive pin properly aligns with its base.

Once the drive pin is correctly lined up with the propeller’s base, repeat the previous steps in reverse order. Make use of all the new parts like the lock washer and drive pin if you have purchased a Minn Kota trolling motor propeller replacement kit to change the old hardware.

How do you tell what thrust my Minn Kota is? 

A quick and easy way to tell what thrust your Minn Kota is is to consult your user manual. The manual that came with your trolling motor will have the thrust listed and provide you with the answer that you need. The thrust might also be listed on your Minn Kota motor. The voltage is usually listed and, in some cases, the thrust too! 

If you don’t have the user manual or the thrust is not printed on the trolling motor, try searching for it online. If you know the make and model of the motor, search for it followed by thrust, and the answer will come up! You might even be able to download a user manual, too, that you can keep. 

If you don’t know the make and model of your Minn Kota, type the serial number in, as this can help you find out the thrust. The serial number will either be in the user manual or printed on the motor, which you can search for online.
