another theory question???????????

[Sked]

I thought I might raise another hopefully interesting question to see what kind of thoughts there are on this. I'm staying out of this one and letting you guy's have all the fun. Enjoy. Here you go.
Does a propeller work as a screw or as a pump?

Ok, I'll bite, it's a screw because to be a pump it would have to have a containment housing to move the water through. It's also a screw when you hit something because it screws up everything under your boat and then screws up your bank account fixing all the crap plus, if it was a pump it would suck and we all know prop boats don't suck!

Great topic and an excellent answer Rex, the basis is all pumps unless they are the diaphragm type have an impeller and all propellers propel by screwing their way through air or water.

It works as a screw, and pulls. There is no push, that's where the slip comes in, as in ventilation. It only pulls.

It's a trick question!!!!
It all depends on if you own a Jones, or If you own a Biesemeyer
