Types of Trolling Motor Propellers
There isn’t a wide selection available, but knowing the type of propeller you’ll be using can save you time while you’re out fishing. Take into consideration where you’ll be fishing most and if purchasing multiple propellers is a good idea.
General use props are likely what came stock on your trolling motor. There isn’t anything fancy about them, but they will get the job done. Almost all propellers are made of a material like aluminum, stainless steel, or bronze with a special coating.
Weedless or Weed-Cutting
These propellers are specifically for areas that have heavy underwater vegetation. The blade is designed to either cut through the seaweed and underwater growth, or avoid tangles.
Speed and Efficiency
Some propellers are designed specifically for speed and efficiency, rather than chopping through weeds. These propellers are especially useful for traveling longer distances since they require less energy from your boat’s battery to operate. Some propellers are even optimized specifically for shallower waters.
Compatibility is the #1 feature you will want to check. The table below shows which propellers can fit which models.
The size of the blade matters in regards to weight and drag. A larger blade will typically create more drag in the water due to increased surface area. However the design of the blade plays a bigger role.
Shape and Blade Count
The shape and blade count are arguably the most important features in propeller design. 3 blades, rather than 2, offer increased output in the water, although add to the weight of the design.
One is not necessarily better than the other and with the price so low, it’s worth trying out 2 or 3 different models to determine what you like best.
How to Replace a Propeller
Replacing a trolling motor propeller is usually quick and easy. For many aftermarket options, there’s only a nut and washer that has to be removed. This makes it easy to replace a prop away from shore if your current one becomes damaged.
With how inexpensive an extra propeller is, it never hurts to have a backup on hand in case you run into issues. Take into consideration where you’ll be fishing and don’t forget to fully charge the battery a day or two before departure.
