3-Blade vs. 4-Blade Boat Props: Which One’s Right for You?

When it comes to getting the most out of your boat, few upgrades, aside from the raw horsepower figures, make as big a difference as the propeller. Whether you’re chasing top-end speed, pulling skiers, or chasing performance in the woods, the number of blades on your prop can change how your boat feels and performs on the water.

Here’s a simple breakdown to help you choose between a 3-blade and a 4-blade prop.

Acceleration & Hole Shot
If you want to get on plane fast, the 4-blade is your friend. The extra blade provides more bite in the water, giving you quicker acceleration and stronger low-end thrust — perfect for heavier boats, towing, or wake sports.

A 3-blade prop, on the other hand, is a little slower off the line but makes up for it at higher speeds.

Top-End Speed
For pure speed, 3-blade props take the win. With fewer blades cutting through the water, they create less drag and can squeeze out a few extra miles per hour on the top end. This lack of drags is a double edged sword, as it can reduce the ability to bite during low speed cuts.

A 4-blade prop trades a bit of that top speed (usually 1–3 mph depending on the setup) for better overall handling and acceleration.

Handling & Control
If you often run in choppy water, carry heavy loads, or want smoother cruising at lower speeds, the 4-blade prop offers better grip and stability. It holds plane more easily and reduces cavitation — that annoying prop slip that robs you of thrust. This increased handling could play a huge difference in performance when trying to move around giant cypress and oak trees in the woods.

3-blades are slightly more efficient at wide-open throttle but can lose traction in tight turns or rough water.
