Premium high-strength stainless steel performance propeller engineered specifically for the Pro Boat Miss Illinois U-34 hydroplane.

Designed as a high-performance upgrade to the stock propeller, this 49 mm propeller is optimized for the unique running characteristics of a hydroplane — strong acceleration, clean water grip, efficient power transfer and stable high-speed performance.

Unlock the full potential of your Pro Boat Miss Illinois U-34 with the Doctor Props 49 mm Performance Propeller.

The blade geometry is designed to convert motor power into thrust as efficiently as possible while maintaining strong and consistent water grip during acceleration.

For a hydroplane, efficient propeller loading is especially important. The optimized geometry helps the U-34 launch cleanly, accelerate strongly and quickly recover speed after turns.

The 49 mm diameter provides a balanced combination of acceleration, top-end performance and efficient power transfer while helping the motor and ESC operate smoothly.

At higher speeds, consistent thrust helps the hydroplane remain stable and predictable as the hull runs on its contact surfaces. This provides improved throttle response and greater confidence during high-speed operation.

The propeller is manufactured from high-strength stainless steel using one of the world's most advanced technologies for producing metal components — industrial metal 3D printing.

Every Doctor Props propeller is individually hand-finished, professionally sharpened and dynamically balanced before shipping.

The result is exceptional manufacturing accuracy, minimal vibration, smooth drivetrain operation and a significantly longer service life compared with standard aluminum propellers.

Every Doctor Props propeller is proudly designed, manufactured and individually finished to deliver maximum performance for serious RC hydroplane enthusiasts.
