It is an earlier K & B 7.5 outboard. I have 2 of them. My first one is very early, no serial numbers. The 2nd is S/N A0020624. A later model. Between the 2, the head different, along with the front plate. Your engine is in between the 2 that I have. They both run great and I have spares left over from when I was racing. It loves high Nitro fuel. I used 60% and they are still running strong after 25 years. The key to keeping these engines running strong is to keep them clean and lubed. I never waited to get home to disassemble after a race. I did it after I completed my heats. Sometimes the races were in salt water.
Your engine is in bad shape externally, but can be cleaned up, although all the bearings will probably need replacing. Need anymore info just ask.
