My 125 mercury outboard will not want to come out of gear and stays idled up high sometimes. Once it was stuck at wot and once I could move the throttle handle down almost into nuetral. Both times I shut off the key switch and then was able to get it in nuetral. However upon restarting the motor it was idled up pretty high. I shut it off and tried moving the throttle around but it wouldn't go into reverse. After moving the throttle back and forth and wiggling cables ect.., I was somehow able to get it idled down again. I cannot figure out what causes this though. The last time it happened I got it home and disconnected the throttle and shift cables and was able to shift the motor in gear by hand and the throttle cables move freely while disconnected. I would like to fix this myself, but I'm not sure where to start or what could be wrong. I would appreciate any and all suggestions on where to start.
