I have been airboating since the 1970’s and have run Sensenich propellers on strictly nothing but aircraft motors, from 4-cylinder to 7-cylinder radial engines. Then I changed to Water Walker and have run Water Walker until now.
I got the 4-blade Excalibur from you a few weeks ago, and this prop is it! Bad Ass! Low-end push is excellent, and it has the pep. Everything you need, low, medium, high. Pushing a 15 ft River Master, 520 Continental fuel injected aircraft motor, average RPM with this prop is in the 2,800 RPM range. Plenty of power. Overall nothing to compares to the Excalibur, I highly recommend it.
Engine: 520 Continental
Propeller: Excalibur 72″ 4-blade
