A 75 hp Mercury outboard, serial number OB9655687, I can not find on the serial number chart. One thing I see, is a seven digit serial number, with a OB prefix. The seven digit serial numbers, ( prior to 1985 ), had no prefix. Serial numbers with the prefix, ( OA,OB,OC, ect. ), have six digit serial numbers. Could there be an error in the serial number posted?
There is a serial no 5965263 for a 1982 Mercury 9.8 There is a serial no 5965263 for a 1982 Mercury 9.8
