I am trying to repair my motor and need the year or model number in order to get parts. ID plate is missing. It is a 20HP Merc. Engine cover is black, with 2 chrome bands around the engine cover and inbetween the bands it says Mercury painted in white and above Mercury it has 3 lines that go from chrome to blue and then curve down and become like a flag and end in red. At the rear of the engine cover it has MERC200. It has square exhaust ports, remote port is on the tiller side of the motor, the engine mount part number is 1427-5612. Inside lower unit part number is 1627 with 6006 under it. On top of the waterpump part# 46-77125. Again all I need is either the model number or year of the motor, both would be great.
