Good Morning everyone, was wondering if I could get some help/suggestions

I have a 2002 Yamaha 2 stroke 225 hp, OX66 Salt Water series engine. This past fall my marine mechanic helped me winterize it and prepared it for winter. I maybe going out of the country for a cpl of years thus leaving the boat covered and protected inside a barn for the next 2 years. Obviously before we placed it in storage we placed Stabil in the fuel tank and flushd the engine with marine grade anti freeze

Is there anything I need to do while I am gone or will the trick be, firing it up when I come home in 2 years?

Thanks for any and all help
