Hi I purchased a 1 cylinder outboard from the junkyard today for $20. I was reluctant because the stickers are all barely visible but you can see it says MONO on it and even sort of read the operations instructions. It had really good compression so I said why not?! So I took it home, checked the gear lube, put fresh gas in it and it started right up! I revved it a little and it was quite responsive so overall I think I did pretty good. What I’d like to know is if anyone can give me any information about this motor and how to find serial number info or whatever you can. I know it’s a mono made by Tecumseh and is an early 60. That’s all I got. Thanks in advance!
