Even in neutral the 2000 Mercuriser outboard with 400 hrs accelerates to full throttle within 20 seconds or so of starting. Otherwise, she starts and runs perfectly. Any ideas?
I would start by checking the throttle assembly when this happens and see if the throttles are actually opening ( IE, the throttle cable somehow being pulled and opening up the carb throttle plates. )
UPDATE - I got to the bottom of the problem. I small piece of wire had broken loose and was jammed into the carburetor causing the acceleration. Thanks for the help. Much appreciated. Sam
