Thank you you any insight you can give. My new to me 1999 Chaparral 200LE has no pitot tube mount point screw holes anywhere on the hull or transum. And there is no pitot tube mounted that I can locate. There are no patched holes that might have been a mount point. I have not had the boat in the water. I have followed the speedometer's hollow tube to the rear of the boat in a bundle containing wires, cables, etc. to where the bundle goes down behind the motor & out of my sight. I do not see anything on the transum or I/O that seems to be a water pick up or pitot tube. Previous boat owner not available for me to ask questions. Is this boat's speed measured without a pitot tube? If it requires one, where would it have been mounted originally? There is a black plastic oval inserted into the bottom rear of the hull that i suspect is the inoperable depth finders pick up. Could that hull insert be part of the water pressure pickup for the speedometer? All guidance is appreciated.
