Hi All...


I have a '76 Century, Raven 180, and when I put it in the water for
the first time this year, the speedometer failed to move. It usually
starts to wiggle at about 10-15 knots. Sunday it didn't move at 25
knots per the GPS. I checked to see that the speed probe was down,
and it was. Yesterday, with the boat up on the trailer, I squirted
some air into the speed probe, but still didn't see any needle
movement.


Is it just a tube that carries pressure to the speedometer? And is
there a way to test the speedometer out of the water? Can a bug climb
up the hose a little way and plug it???


Any ideas will be most appreciated.

Rich.....
