Hi there, having trouble one day in after purchase of our Honda 225 on a 2004 Dorado Scout. We’ve had it serviced and the computer Found an overheat error code. We have since done a salt flush as well as replaced the thermostats. Took it for a ride and within 10 minutes the beeping started again. The beeping is long and the motor goes into idle but then restarts right away. We are not sure if we should move into replacing the oxygen sensor or if there’s something else that somebody on this board knows specifically related to this engine and with these symptoms. Please advise! This is not good for our marriage!
