Propeller Selection Guide

If your boat's load varies seasonally or with different activities (like hunting), consider having two propellers: one optimized for light loads and another for heavier loads. This approach ensures optimal performance throughout the year.

Refer to our selection chart (below), which outlines the critical factors we consider when designing propellers:

• RPM: We recommend operating motors between 4000 and 4300 RPM for best performance. Some high-performance engines may peak between 4200 and 4500 RPM, but higher RPMs can accelerate engine wear significantly.
• Gear Selection: Certain brands, like Mud Buddy, offer customizable gear options. This flexibility is beneficial for adapting to horsepower changes due to modifications or varying loads.
• Altitude: Engines used above 4000 feet experience reduced horsepower (approximately 1.5% per 1000 feet elevation). Adjusting to a smaller pitch propeller can compensate for this loss. Mud Buddy engines, for example, often come with adjustable gearing to optimize performance at higher elevations.
• Number of Blades: Choose between three-blade and two-blade propellers based on your operating conditions. Three-blade props generally offer smoother performance in open water but may not perform as well in mud or shallow waters. Two-blade props, with their larger blade surface area, excel in mud and shallow, hard-bottom environments.

If you're satisfied with your current engine and boat performance, simply replace your propeller as needed. If you're looking to optimize RPM, adjust for seasonal loads, or improve overall performance, explore our wide range of propeller options.

After selecting a propeller, test it in open water. If your RPM falls outside the 4000-4300 range, consider opting for a propeller with a smaller pitch to fine-tune performance.
