As has been said a carb clean and a fuel pump diaphragm kit, new plugs, fuel filter.
These things are pretty simple to service and fix and with plenty of help from youtube clips, I actually have a official merc workshop manual for my 60hp 2S so if you needed a copy of a page or two I could send you them.
You also learn plenty by doing it yourself.
just a thought.
