So I am totally new to working on boat motors. I have a 1962 9.5 hp johnson outboard that I got last year. What do I need to do to get it ready for this spring? The only thing I really know is changing the oil. Is there only a lower oil unit? And what kind of oil should I put in there? I was an idiot at the end of last year and didn't do anything for storing it over the winter. I did store it in my basement, so it was sitting in 65 to 70 degrees all winter. Thanks for any help!
