I have a 1989 2.4 200 HP power head that I am looking to get rid of. I had one cylinder that the retainer for the ring let loose in and damaged the piston. All the rest were good. This power head does not include any electronics but does include the carbs. The serial number on the block is 0c108100. The block is located in Rosoce, IL. If you have any questions feel free to call me at 815-985-5911.
