In my e-outboard tests I couldn't measure the speed of the boat. I
bought a pitot tube, but the speedometer I found for it goes from
0-60 MPH and the first marking is at 10 MPH. The next one is at 15.
(From 40 to 60 each MPH is widely spaced - exactly the opposite of
what's needed.)
Blowing into the pitot tube, it takes all the pressure I can make to
move the needle just a little.
There must be some more sensitive transducer that can be used with a
pitot tube? Or is there some other way to measure speed that doesn't
cost a lot?
Cheers,
Craig
