Just says... Yamalube® 4M FC-W®

Doesn't give a weight because I would think different parts of the country would need different weight oil.

The 4M FC-W just means 4 stroke fresh water cooled. Your owners manual will specify which weight to use depending on operating conditions. 10w30 is just fine for year round conditions.
