I know this is off-topic for the GMC list, but there is such a
cross-section of skills and experience here I thought I would just throw it
out.
I have learned that a $4000 boat motor came off of a bass boat near the
place where my wife and I go fishing. Some sort of Japanese
four-cycle outboard thing. It was not running when it fell off the boat and
is fuel injected. So there are a number of things that will not be wrong
with it due simply to sinking
The water is very murky visibility is only 6 inches or so, so a camera like
the ones used in icefishing won't do any good. The water is just too murky.
You would have to be literally on top of the motor before you could see it
with the camera.
The sportfishermen quality side scan sonars have been tried but the
relatively small motor cannot be distinguished from the bottom.
The motor is in only about 13 feet of water however there is a strong
current and there is quite possibly submerged trees or other underwater
hazards, not to mention alligators and the water is cold. Nobody is going
diving for this thing. If it can't be brought up via a hook or claw or
something, it's staying down there.
I don't think I have the electronics skills to build a towfish magnetometer
or metal detector. Also, I've been told that I cannot simply extend the
cable on my little coinmaster metal detector so that I could stick the
sensor below the surface while I stay on top with the rest of the metal
detector. It has something to do with the length of the cable and the way
the metal detector works.
I am open to suggestions, advice, or even interesting stories about crazy
things that y'all did in your younger days in similar situations. At least
it might be interesting. :-)
