Re: Newer OMC V-6

The number you gave on the core plug is a replacement power head assy number. If you look on the port side of the swivel bracket up top just to the left of the steering arm you should find a sticker. The model number should be like E or J150/200TLES the horsepower will depend on what size engine it is. There will probably be another letter at the end, but that is a production code number. ES is for 90. The word Introduces is used as code word for years. I is 1 thru S as 0. The numbers just keep repeating.
The engine you describe was a model built for Tracker Marine. Same engine only decal changes.
