With modern technology being what it is, it is relatively easy for "Joe Motorboater" to achieve horsepower levels unheard of in the seventies.  My question is "how come nobody builds a pump larger in capacity, volume, diameter, whatever ya wanna call it?    If you are running better than say 600 hp  I would think you could move enough water to warrant a larger pump.  Am I wrong?   Surely someone else has thought of this . . .

GC, here is some "food for thought", my friend Tim in Oregon thought the same thing you did, he is the one that built the T58 turbine powered jet boat, that boat has been tested and tested but if you notice still uses a "12" series pump, now that boat makes 1500+/- HP, it ran up and back a 38 mile whitewater river at a sustained average speed of over 120MPH, what that tells me is the "12 series" pumps have a lot left on the shelf...

I'm not sure bigger would necessarily be any better, I could be off by quite a bit, but then again I am of the mindset that lighter is better, so maybe if the boat is heavier you would be right on que...

I guess this is one of those "wide open debates". I do know that if there was a redesigned pump, I'm not so sure I would ever be able to afford one, its kind of like the VCR when they were first introduced, they were like $600, now you can get one for about $30. 

Cool thread though....

  They are being made. I’m not sure for the industry that we are using them for (Joe boater). I have seen transport fairies in Europe driven by two very large Jet drives. The military is also using a jet for their amphibious personnel vehicles. These are VERY large HP applications though.

in this "sleepy" market not much demand , Things like this are relegated to small entreprenuers and "Joe six pack"  working on his/her own .

Yeah if we want new kindza pumps we have to figure out how to either
1) start a war where they got lot's of rivers 
2) get some jet pumps on the NASCAR circuit
3) solve the oil crisis with a jet pump

Some of you fokkers can gay up just about any thread huh? And Omar is no where around, now that's hard to believe.
