Guys, I have a stupid question but curosity has gotten the best of me. Have a 1992 150 Intruder with the speedo pick up tube on the leading edge of the motor just above the nose cone. It stays full of wood, etc all the time and I take a small drill bit and drill it out. My question is this: What if I were to take a drill bit and place in drill motor to do this and went too far and drill thru the tube. Would that hurt anything other than the speedometer would probably quit working? I have a gps and only use the boat speedometer as a conversation piece anyway.
