Sonic Speed Transducer (Knot Meter)

Hello Everybody,

I am wondering if anyone could provide me with information regarding
the system that measurers the SM 2000's speed through the water. The
boat was recently out of the water for the regular maintenance and I
am now getting erratic readings on the knotmeter. Some times it seems
to be working just fine and then all of a sudden it will jump to an
unrealisticly high indication. Would you have any wisdom to share with
me on this system/problem? I would be most grateful,

Jim
