Re: Test Tank Gearcase Loading?

[David Stanton]

In a test tank, the propeller easily cavitates because water can’t fill in in front of the prop as fast as the prop pushes it back, taking load off the prop, and thus sending RPMs up high. There are dummy load props for use in test tanks that handle the water a bit different to maintain a load on the motor.
Some newer test tanks have baffles that get rid of cavitation like the ones in this link:
