Mystic stock motor on 6s or maybe just 5s?

[704Authentic]

New Mystic Owner. Really, really like this boat. But, you know what happens, got the Bug and gotta see it go quicker. Can you put the stock (listed as: A3630-1800kv) motor on 6s or maybe just 5s. What happens? Will it live? All information is appreciated.

Thanks,

5s will be more realistic on 1800kv 6s would work for a few minutes if you wanna go with 6s get a lower kv motor
