Yup...that's the reason that I ultimately disconnected the aftermarket units that I had. The pressure inside the tube is fine as long as the hose is sound, but if there's a leak from old or rotted hose then the air is replaced with water in the hose and it can get real bad real quickly on your electronics. Stick with a GPS or a transducer with a paddlewheel for speed indications.

If God didn't have a purpose for us we wouldn't be here, so
Live simply, Love generously, Care deeply, Speak kindly.
(Leave the rest to God) 
Silence, in the face of evil, is itself evil. Not to speak is to speak, not to act is to act. God will not hold us guiltless.
