I recently purchased a boat with a yamaha 60hp 4 stroke, the fuel gauge worked for the first couple of trips but now constantly shows the digital fuel gauge as being full, regardless of the amount of fuel i have. i ran the tank empty the other day and it still reads full. 

i pulled the sensor out of the tank and everything seems to be moving fine, e.g the sensor arm. i have no idea whats going on. please help :confused
