The port engine starter stays running on the first start of the day. Turning the batteries off, and then on fixes the problem. Never happens again until another first start on another day. Have replaced the ign. key sw., the relay between the key sw. and starter solenoid, and had the starter rebuilt with a new solenoid fitted. Boat is a 1987 Searay 340 Express. Could there be some electrical logic somewhere that keeps the port engine starter engaged only on the first start of the day?
