No problem with the gun.
You will need a sport fishing license. I think you can get one for a week or for just few days. I don't know in Mazatlan but in some places getting a licence could be a litlle hard, but Mazatlan has a lot of sport fishing boats so it shouldn't be a problem.
For spearfishing the rule is no pneumatics, freediving only, the fishbag limit is 5 fish/day/person.
I wish you nice dives down there
