Standing-by...

Ok Tom, attached another headache, dealing with the pump technology. After some digging in old sediments I found a test report on a pump with performance close to the preliminary optimum I calculated before.

Next I will deal with the inlets, beeing the root of ethernal misunderstandings among boaters (and, in fact among some waterjet manufacturers as well!!!!).

baeckmo,

Thanks for your recent efforts.

It appears the inefficiency of a jet drive may not be outweighed by the advantages (i.e. directable thrust, concealed moving parts, and other unknown potential positive benefits).

Also, the time delay and lack of dialogue aren't helping me to make an informed decision about attempting a jet drive in my unique application.

So, I am abandoning the idea.

-Tom
