Yeaterday I bought a 1966 Gulf Stream 17ft. with a Mercuiser 1 Stern Drive Unit serial # 2028545 ..Mercuiser Marine Engine serial # 2045309 Model # 120. The price was right. Every thing for $300.00. The boat has not been used for 8 years. It has been covered up and except for some TLC it checked out pretty good. Did find some soft wood top top of Transom. Didn't notice any soft wood on floor, but it is coverred with carpet. I will check this out later. Also the boat has a removal hard top. The owner didn't have any Manual on the boat. There is a operation and Maintenance Manual for the engine. Does anyone have any information where I can get parts for the engine and drive unit? Thanks
