I have a 1988 DT9.9. I just got it. When the guy hit the start button it ran like a champ. So I bought it. Put it on the boat and went to test run it. It won't start and stay running unless I push and hold the run button. Is that thing supposed to lock in and out depending on weather you want the motor to run or not? What am I doing wrong. Got to get fishing! Please Help!
