2000 Mercury 125

[triton17]

I have a 2000 Triton TR17 with a 2000 Mercury 125, I am the original owner. The boat was used regularly up to 2004, then rarely from 2004 til 2010 with no problems. It has not been used/cranked since 2010. It was running fine the last time it was used. I would like to start using it again on a regular basis. Here is my question; Could someone please write out a list of the things you feel I need to address / check / replace? I have a list in my head but I am not an experienced outboard mechanic and I'm sure your list will make a very big difference when it comes to getting this motor ready for service again. And please give me your opinion on whether to continue using the oil injection or not at this point. thanks for your time and help.
