Re: speedo sensor for 115 yamaha

If it's on the motor, it's on the leading edge of the gearcase a few inches up from the nose, a tiny hole. Or you might have a plastic thingy hanging down off the transom called a Pitot. Pickups frequently clog with debris that has to be cleaned out. Removing the hose from the gauge and blowing backwards with compressed air usually clears them out. Sometimes you have to poke at the hole with a paperclip. In a worst case, a tiny drillbit may be needed to dig it out. Also check for kinks or pinches in the hose. It's about the size of large aquarium air hose and probably black.
