Bob, As you may remember..I bought a 25 horse Mercury in mid-may.. The last three times we went out I have experienced the throttle sticking when I tried to gear down to neutral. Twice I had to push the button at the end of the tiller handle to kill the motor and then the handle would turn easily into neutral. It has a long rod from the handle that I thought might be sticking so I used a good silicone greese. It seemed to be okay but stuck twice the last time we went out. It doesn't do every time? The last time it did it on me I reved the motor up and when I turned the handle down it went down without me shutting off the motor. I know the motor is under warrantee but I didn't want to have to take it down there, drop it off, then drive my truck back later to pick it up.. Other than that the motor it great..love the fact that it is a 4 stroke. Have any ideas???
