As long as it's TWC (two cycle, water cooled) it should be fine. I use TWC III synthetic.

TC-W3 synthetic oil is good in most 2 cycle water cooled outboard engines, regardless of their age.

The full synthetic may be considered an overkill in motors that mix 50:1 (or premix 50:1) but it will not hurt anything. Well, maybe the wallet..................
