We could use your year and serial number. The first thing I did was get a compression test and then decided mine was worth investing in. (modestly at first). Then the fuel system and then electrical. Lower unit just finished. Takes some time, but if you are patient, things will come together. The folks on here will be helpful. They were to me.
