How to Choose the Right Boat Propellers for Your Next Fishing Trip

Like many other forms of outdoor recreation, boating exploded during the COVID-19 pandemic. And like other sports, successful fishing requires the right equipment.

Boat fishing requires agility and responsive maneuvering. The right propeller can help you get the best performance out of your boat and could make all the difference on your fishing expedition. But with so many boat propellers on the market, it can be difficult to know where to start.

Fortunately, there are only a few main categories to consider when selecting the right prop for your boat motor. Boat props come in all shapes, sizes, and compositions. There are many different features to consider, but the categories below are the main ones to focus on.


Boat propeller materials vary widely based on manufacturer and purpose. These include nickel and bronze, but aluminum and stainless steel are the most common.

Aluminum props are more budget-friendly and are available in almost any size and design. Stainless steel will afford superior performance and durability.

Both are resistant to corrosion, although stainless steel is less likely the chip or break with wear. Also, you can repair stainless steel boat propellers, while you will most likely need to replace damaged aluminum ones.


Boat propeller sizes also vary. In general, the larger the propeller the more water it will push. This does not only impact top speed but also acceleration. It is also important to note that having too small or too large a propeller will strain your engine.


Boat propeller pitch is the amount the prop will move forward in one full rotation. The greater the pitch, the more power it transfers.

Besides size, pitch is the most important consideration when selecting a propeller. A good rule-of-thumb is that increasing pitch by about two inches will result in a 300 to 400 RPM reduction.

Blade Number

You might assume that, like the overall size, the more blades on a prop, the more water it will push. That is accurate, but it does not necessarily translate to better speed. In general, three-blade propellers offer optimal top-end speed.

Four- and five-blade propellers have their advantages though, namely transmitting more power in take-off. If your boat is having trouble planing, a prop with more blades will help. Otherwise, as long as you select the right size and pitch, three-blade propellers will be sufficient for pushing most boats.


Many propellers incorporate a curved tip or “cup” at the edge of the blades. This allows for better acceleration, rake, and higher top-end speed.

Cupping is especially effective in boats with propeller shafts that can be trimmed to bring them near the surface of the water. It will not supplement matching the right prop size and pitch, but it can offer an added boost to your boat.
