      For those with a good budget, there are 
    doppler ultrasound "speedometers" that have no rotating wheels beneath the 
    boat. Just a transducer like that of a depthsounder.
     But that "fountain" of water coming into your boat when you pull the impeller 
    shouldn't admit more than a couple of pints with a little practice, it really 
    should not terrify anyone. Here we try to remember to pull the impeller when 
    securing the boat, so it stays out of the water and unclogged until the next 
     All of the reasons you mention do contribue to why sailors (not merchant 
    marine, but pleasure sailors) are making so much use of the GPS. No water, no 
    wiring, no mess. Only an appetite for penlight batteries and an illusion of 
    ground speed.
     If you are really down to one last bronze spinner, you might consider taking 
    it to a foundry and getting a quote on casting a few more--while you've got 
    the chance. Many foundries will take in outside piece work that way, and the 
    price is often less than you might think.
